Mild exercise, of types appropriate to the various stages, will help keep the circulatory system healthy, increase pelvic muscle tone and strength, and help to smooth out mood swings. Done right, you can lessen the severity of backaches, keep joints flexible and firm, and improve sleep.

Mild exercise helps release endorphins, which can help elevate mood. Proper strengthening and toning of the back, buttocks, and thighs helps improve posture and relieve backaches. Daily stretching keeps joints well-lubricated with synovial fluid. Moderate working out burns up some of that anxious energy, leading to more restful sleep.

Three exercises in particular are appropriate for most soon-to-be mothers: swimming, spinning and pelvic strengtheners.

Swimming is a great cardiovascular exercise and has the added benefit of easing the back and leg burden during later stages. Most women enjoy the (all too temporary) relief during those final months. Keeping the cardiovascular system active helps regulate the endocrine system and keeps muscle tissues full and joints flexible.

Swimming has the added benefit of working nearly all the muscles and joints in a low-impact way. Knees get a break from the higher stress of carrying additional weight and breathing exercises can be done while wading, in between laps.

Spinning, provided it isn’t done too strenuously, can be a terrific exercise up until the last two months or so. The cardiovascular benefits are similar to swimming and the legs as well as stomach and pelvic muscles can get a really good workout. That benefits fitness overall, while helping to keep legs in shape to prevent falls. It also helps two particular muscle groups that will be needed during delivery.

A 10-minute routine on a stationary bike is plenty, keeping in mind that you should stop at the first sign of bleeding, fluid loss, dizziness or intense pain.

‘Kegels’ are a commonly recommended exercise – and for good reason. They help develop those very specific muscles that aid in giving birth.

To find the right muscles to focus on, pretend you’re trying to halt urination in the middle of elimination. Squeeze those specific muscles for a few seconds, then relax. During the exercise, avoid tightening the legs or stomach. That will help isolate the right muscles you need to zero in on. Remember to continue to breathe normally, in and out slowly and regularly.

Before beginning or continuing any exercise routine once you know you are pregnant, be sure to have a long talk with your physician. Many of them are rushed, but be firm and get the answers you need in order to stay fit in a safe way.

Stop immediately any activity that produces heart palpitations, back pain or light-headedness. Don’t concern yourself with weight loss during pregnancy, just keep fit in order to maximize your overall health and mental well-being.

Diabetes comes in two types, Type I and Type II. In either case, the body has difficulty regulating the level of blood glucose. Glucose is the primary source of energy for the body’s activities.

One basic reason is the inability to produce the proper amount of insulin, a hormone that helps transport glucose to the cells. In Type I diabetes the body can’t produce adequate insulin, so the loss has to be made up from the outside, usually via injection. This is the more serious type and control of the condition requires obtaining medical advice.

In Type II diabetes, individuals produce insulin, but it’s less effective in performing its role as a transport aid. This is the type that is more likely to occur as we age. The kidneys become less efficient and we tend to adopt a more sedentary lifestyle. We sometimes worsen our odds by being more indulgent about food. The long term effects add up.

Type II can be controlled with diet and exercise and with careful self-monitoring under the care of a physician, the effects can be minimal.

Exercise helps increase insulin sensitivity. It also reduces body fat, which helps regulate the amount of glucose needed and used. Weight training helps by increasing the metabolic rate, reducing body fat. At the same time, it increases the use of glucose used by muscles and improves the ability of muscle tissue to store it. All those help achieve the preferred glucose level.

Get professional advice and start any new program slowly, particularly if you have not been active habitually. Pain from doing too much too soon is one of the leading factors that discourages people from continuing a program. Also, the body needs time to adjust to changes in hormone level, metabolic level and thus glucose and insulin levels.

Be sure to warm up for five to ten minutes at minimum. Easy stretches and low-impact, low heart rate exercise help get the muscles infused with blood and joints limber. Take care not to exercise when it is too hot. Heat stroke (from too high an internal temperature and lack of fluid) is a risk, and more so for those who are older.

Humidity levels are a factor to consider, as well. The body’s ability to regulate internal temperature is made less efficient when the moisture content of the air is high. The heat doesn’t travel out of the sweat and off the skin so readily. On hot and/or humid days, wear loose fitting clothing and reduce the time and vigor of your routine.

Walking is a great way to get started. Try to walk on grass rather than concrete or asphalt, but with good shoes you do either. An hour per day every day is best, but even 20 minutes three or four days per week will help.

Persistence is key. Reducing the odds of getting diabetes, or controlling it once you have it, require permanent lifestyle changes. But the benefits are not only the absence of a debilitating disease, but a healthy body and improved mood.

Particularly today, when there are so many electronic alternatives, young people may exercise less than they should. It’s during the formative years that individuals lay the groundwork for what later become healthy or poor habits.

Kids will usually become quickly bored with routines designed for adults. But the activity doesn’t have to involve organized group sports, either. A gentle jog with an adult, a tennis game, swimming, golf, martial arts, bicycling, dancing, gymnastics and many other sports are enjoyable for the younger crowd.

Kids are usually sensitive to anything that appears inconsistent or hypocritical from adults. Be prepared to follow your own advice and exercise with them. That also helps parents share quality time with their kids outside the house and during activities that benefit both. Parents get the added benefit of monitoring to ensure that the kids are exercising in a safe and proper way.

Like any routine, if it produces pain – even the day after – the individual is less likely to continue. Keep it simple and build up the difficulty and length gradually. Kids are more flexible, but they too need to warm-up and gently stretch before engaging in vigorous exercise. A few minutes of static and dynamic stretching will help avoid injury.

Exercise routines should take into account the age group of the individual child.

Children from about 4-7 should focus primarily on developing basic physical skills, such as coordination and balance. These are the years when motor skills, eye-hand coordination and other things adults take for granted are still fluid. Children take to these activities naturally, as well. Jumping rope, hopscotch and other simple activities help guide the development of these skills.

From the age of 8 or so, exercises can become more vigorous in order to keep that active metabolism from turning food into fat. Here again, though, adults need to guide kids in order to build good habits and avoid injury. Weight machines are almost always a bad idea for pre-teens, for example. They’re risky and unnecessary.

Gymnastics, by contrast, helps build on those basic motor skills learned earlier while developing strength, balance and keeping the endocrine system active and healthy.

For teens, the field is wide open. They have the basic bone and muscle structure that gives them the potential for high performance activity in a wide variety of activities. But here, too, the possibility of injury remains for those who don’t get the proper guidance.

Teens are inclined to roughhousing and rebelliousness. Give them an outlet that directs all that energy and independence to the achievement of positive goals – fitness, endurance, high scores.

No reputable researcher will claim that exercise will repair a weakened or diseased immune system. Nonetheless, a broad spectrum of studies confirm that moderate exercise can help sustain and strengthen it, even when the effects are indirect.

The role of exercise in helping to lower stress – and the subsequent beneficial effects on health – has been widely studied. Here the studies are less clear, contradicting one another in some details. But overall the conclusion is the same: moderate, regular exercise helps the immune system by moderating the effects of stress.

Most studies carried out over the last 30 years agree: a continual high level of stress has a number harmful effects on overall health. People who experience high stress get more colds, suffer more digestive tract problems and have more frequent bouts of fatigue. Part of the latter is indirect, since it tends to lead to lowered amounts of restful sleep.

Regular exercise helps relieve stress. It does so directly, by providing an outlet for, and consuming much of, the nervous energy produced by stress. It also helps indirectly by shifting one’s focus away from the external factors producing the stress.

Exercise can help the cardiovascular system, which in turn improves blood flow, carries away toxins from muscles and organs, and helps keep the kidneys and endocrine system working well. It helps remove germs and circulate antibodies.

All those promote a healthy immune system by lessening the body’s susceptibility to disease, while increasing the robustness of the immune system itself.

Exercising increases the body temperature slightly. This, as anyone who has suffered from a cold knows, is the body’s natural response to colds, flu and other diseases. The increased temperature helps kill the infecting organisms.

A study at the University of Colorado, Boulder suggests that moderate exercise helps prevent colds as well. It showed that individuals are less likely to get sick after stressful situations when they had engaged in a regular program of moderate exercise. Those that began exercise only on the same day as the stressor didn’t enjoy those benefits.

The study was carried out on rats, but one of the reasons those mammals are used is the similarity in some systems, and their responses, to humans.

Exercise programs, undertaken consistently and correctly, help improve body image – that’s one of most individuals primary goals in making the effort, after all. That improved body image often leads to higher levels of confidence and relaxation in social situations. That in turn helps reduce stress and enhance the immune system.

Whether the effects are direct or indirect, exercising can help you support and enhance your immune system. That leads directly to better overall health.

When and how you can begin exercise routines after major surgery will vary with the type of treatment you had. Most physicians will recommend at least a week, sometimes 6-12 weeks, of recuperation before even attempting regular routines. Consult your physician.

Most people will want to perform some kind of toning exercises and probably induce some weight loss. Most surgery reduces the metabolic and activity level – leading to weight gain and flabbiness.

Be sure to keep well hydrated, no matter what form of exercise you perform. This is helpful in order to keep the endocrine system functioning properly and aids the process that keeps joints lubricated.

Take it slow and return to your pre-operative level gradually. Here are some specific exercises for two different types of surgery. Again, consult your physician first.

Breast Surgery

About a week after surgery, you’ll still be experiencing discomfort. But recovery will be aided by some simple arm exercises. Perform steady breathing during the following:

Lift the arm on the operative side and simulate hair brushing and eating. Do a few reps at most the first few times. Raise that same arm above the heart for an hour, two to three times per day in order to reduce swelling. With the arm raised, gradually open and close the hand, building up to clenching a tennis ball as the discomfort decreases. Alternately bend and straighten the elbow.

After a couple of weeks you may feel fit enough to perform the following exercise.

Hold a broom handle (with the broom cut off), in both hands with your palms up, arms outstretched. Lift above the head and hold for a few seconds, then lower the broom handle to the pelvis. Repeat several times.

Hysterectomy

In these exercises, you’ll work the abs, pelvic, and back muscles. As with any routine, be sure to get the advice of your doctor before beginning.

Lie on the floor, knees bent, hands behind your head. Press the small of the back gently into the floor, then more firmly. Don’t try to work ‘through the pain’.

Raise your head and shoulders slightly off the floor, paying attention to the contraction of the abs. Take care not to move the chin toward the chest. Then slowly lower the head and shoulders back to the floor. Repeat several times.

Lift the hips, hold for a few seconds, then lower them. Do 10 reps. Then, alternate with the abdominal exercises. Roll over onto the knees, making sure you have some knee pads or carpeting to soften the point of contact.

Slowly raise one arm and the alternate leg. Alternate. Right arm out, left leg out, then, left arm out, right leg out. Hold each for a second or two, switch and repeat 10 times.

Again, don’t try to exercise if you feel intense pain as distinguished from mild discomfort. Take it slow, building up strength over time.

The lats are the large ’side’ muscles that make a man triangle-shaped. To demonstrate how they are used during squeezing a tennis ball, try it! You’ll quickly feel a tensing of the muscles on the side of the arm you use. It’s especially noticeable if you have back pain.

Any sport will require strong back muscles, for speed and coordination, for balance and movement and for providing a strong ‘pillar’ for all the limbs to move off of.

Here are some simple exercises to help stretch and strengthen those all-important back muscles. Most of them are better performed on a firm, but not hard surface. While you work the muscles, you don’t want to cause undue, painful pressure on bony parts of the body.

Knee to Chest

Lie on your back and clasp your hands behind one thigh. Pull slowly toward the chest, keeping the other leg flat on the ground. Vary the action by flexing the ankle – first pointing the toe, then pulling it back toward the knee – at the same time as you stretch the leg.

Hold each position for 5 seconds, then switch legs and repeat. Do 10 reps.

Rotations

Lie back, knees raised and together, feet flat on the floor. With your arms extended and near the body, and your palms flat on the floor, lift the feet off the ground slightly and rotate your trunk by moving the knee. Move the knees slightly left, then right.

Over time, as you become more flexible and build strength, you can increase the range of motion. Ultimately, you should be able to touch your knee to the floor.

Alternate the action by crossing your arms over your chest, then repeat.

Pelvic Press

Lie down on your back, knees raised and feet flat on the floor. Push the small of the back into the floor, feel the tension in the lower abdominals. Vary the action by moving your feet together and performing the exercise, then slightly apart and repeat.

As you press into the ground, hold for 5 seconds, but continue to breath slowly and normally.

Pelvic Lift

Lie on your back, knees raised and feet flat on the ground, arms crossed over your chest. Keeping the legs and knees together, raise the buttocks up slightly and hold for 5 seconds. Lower slowly, count to two, then repeat.

Remember to breathe normally through the exercise, in and out slowly.

Dog Stretches

On all fours, raise your head, eyes forward. Lower your arms and arch your back, hold 2 seconds, then resume the starting position. Slowly extend one leg, as near parallel to the floor as you can. Hold 3 seconds, then put the leg back into starting position.  (If this produces back, hip, or leg pain stop immediately.)

Switch legs and repeat. Vary the exercise by extending the leg with toe pointed, then flex the ankle perpendicular to the leg. Hold for 2 seconds and repeat. Do 10 reps for each leg.

Never perform these exercises if they produce back pain. Mild discomfort from inactivity is natural. Pain is a signal that something is wrong. Consult your physician.

A good workout routine will test you, but shouldn’t damage you. As muscles get used, especially somewhat beyond their usual range, lactic acid, micro-tears and other physiological changes occur that result in muscles being built up stronger than before.

But if you are experiencing back pain, neck aches, knee joint soreness and other symptoms, you should consult with an expert. Your technique may be wrong, you may be trying to do too much, too soon, or you may have a medical problem that should be addressed.

Work up to any vigorous routine slowly. How slowly will vary from person to person, depending on age, experience, prior exercise routines and overall fitness. Get muscles warm and limber before cranking it up. Most strains and rips result from being too cold and not stretching, or extending more than you’re ready for.

Warm-ups should take at least 15 minutes and include very gentle jogging in place or jumping jacks to get the cardio and lung systems working well. They should include some slow, gradual stretching to get joints lubricated and muscles relaxed and gently lengthened. Warm-ups that are too short can easily lead to stretched or torn cartilage that takes a long time to heal.

Don’t let inexperienced trainers, or so-called ‘friends’ embarrass you into believing you have to get out and run five miles two weeks after an injury, surgery or other debilitating condition. Physical therapy and exercise sometimes requires that you work against discomfort, but you don’t leap over tall buildings the first day out.

Every person committed to fitness will want to push him or herself to achieve excellence. But an attitude that leads to overdoing it is counter-productive to your goal. You’re working to improve or maximize health and overall body tone and strength – not proving you are ‘mentally tough’.

Before you begin a new routine that involves activities that are unfamiliar, get guidance from an expert. Next to bad warm-ups or overdoing it, incorrect technique is the leading cause of injury. If you don’t know how to use a station at the weight machine correctly, don’t be embarrassed to ask. No one is born with this knowledge. Anyone who mocks you for ignorance, isn’t someone whose opinions you have reason to heed.

Be aware of your environment while you go through your routine. It’s easy to get into a rhythm, get concentrated on your workout and end up crashing into a wall or a nearby person. Jogging especially requires that you pay attention to the surface you run on and the people and cars around you. No shoe in existence will keep you from slipping on a muddy patch. Only awareness and good reflexes can help.

Stay within your comfort zone as you gradually expand it. One of the foremost reasons people give up on workouts is injuries produced by working beyond their capacity. That makes working out no longer fun. Building up, while you build out, to increase your ability to do more, faster will keep you going for years to come.

Your health will thank you for exercising common sense, while you exercise your body.

Exercise for the over-50 crowd is decidedly healthy. As people age, several changes occur that exercise can help slow or reverse. Metabolism slows, leading to increased fat accumulation. Artery passageways often narrow, leading to higher blood pressure and lowered flow. Bones become thinner and more porous, a condition known as osteoporosis. Muscles and skin lose tone.

Those effects can be retarded or even turned back to a degree with regular, age-appropriate exercise. The American College of Sports Medicine suggests 15-60 minutes of aerobic (oxygen-enhancing) exercise a few days per week.

One goal among others is to raise the heart rate to 60-90% of the safe maximum (220 beats per minute, minus your present age). A good cardiovascular workout – a 30-minute brisk walk or three 10-minute walks per day, mild jumping jacks, gentle jogging in place, swimming, a dance routine or any other method – helps keep the heart and blood vessels healthy.

Strength-building exercises help keep the muscles toned and keep weight and blood sugar levels at appropriate levels. Balance exercises can help build good leg muscles, leading to better support for joints and less likelihood of a fall. (The National Institutes of Health report 300,000 hospital admissions per year for broken hips, many of them from seniors falling.)

Gentle static and dynamic stretching exercises help keep muscles flexible and joints lubricated. That helps out with balance, but it also maximizes range of movement. That means better coordination and less pain during both exercise and everyday activities.

Endurance exercises help keep the heart and lungs healthy as well as keeping muscles toned, joints moving freely and other body systems functioning well. A slightly higher metabolic rate stimulates a variety of organs to produce needed biochemicals. The human body functions better, longer when it is subject to mild activity than when sedentary for long periods.

All these activities help raise the onset age of osteoporosis and to minimize its effects after it begins. Non-insulin dependent diabetes mellitus is less likely for the physically active. Certain forms of heart disease are less likely for those who exercise moderately later in life.

There is ample evidence that moderate, regular exercise helps the psychology as well. It can decrease the severity of depression and heighten mood. The social aspects can help with the isolation that older people sometimes feel, especially as friends and loved ones are no longer part of their lives.

Older people should consult a physician or trainer (preferably both) before starting any new exercise program. Begin slowly, especially if exercise has not been part of your lifestyle. Build up flexibility, strength and endurance gradually.

If you have a medical condition, be sure to discuss your plans with a physician and sports expert to develop an exercise routine appropriate to you.

As you exercise, you consume energy measured in calories. When you consume enough to deplete the available energy, and enough to reduce the sugars that convert easily, the body goes after stored energy. That stored energy is largely in the form of fat deposits in adipose tissue.

But that process takes place non-selectively. You don’t get to choose which fat deposits the body converts. That means, you can’t ’spot reduce’ by working on your abs. The effect is still achievable, but doing abdominal exercises alone doesn’t target that fat.

When you focus on the abs, you will build strength in that area, by increasing the muscle mass in those muscles. That’s helpful for a number of reasons. It keeps a firm, strong layer of muscle which helps keep the stomach and other internal organs well inside the plane defined by your hips. You get a nice trim, flat look.

Abdominal exercises help in another way, too. Since the abdominals are large muscles, they consume a proportionately larger percentage of energy than, say, your jaw muscles. That means that as you work them, they have to be supplied with more energy to move through the range of the exercise. That burns many calories, resulting in weight loss and fat reduction.

There is no gadget, supplement or drug currently on the market that will do that safely and effectively as a substitute. It can only be done through proper diet and regular, moderate to heavy exercise. There’s no shortcut to a trim waist, at least not yet.

The effect is also limited by genetics and age. Some people store more fat around the middle more readily than others. Gender, obviously, makes a difference as well.

Many women in their 40s will naturally develop a pouch in the lower abdomen as their hormones change. Many men will naturally develop ‘love handles’ at the side, since they store fat in adipose tissue there more readily in their 40s than they did in their 20s.

In order to achieve the desired effect you have to approach muscle fatigue. There’s no need to perform a hundred crunches to accomplish that. Done correctly, 20 reps is enough. You don’t even have to go to the gym. You can do pelvic tilts while sitting in a chair in the office.

But for best effect, warm up and try the following:

Lie on your back, with your knees raised and cross your arms across your chest. Then lift your shoulders off the floor and hold for 30 seconds. You can feel the effect on your abs already. To make the exercise more difficult, put your hands at the side of your head. Don’t use your hands to lift your head, just keep them still. For maximum effort, put your hands above your head, then perform the same shoulder lift and hold, focusing on the abs.

Feel the burn. Repeat daily for 10 minutes or twenty reps. In a few weeks, you’ll see definite results.

There are three basic types of stretching exercises that help accomplish these goals: static, dynamic and Isometric/PNF.

Static stretches are the most traditional type, encompassing the more or less standard ‘pull to maximum end point, hold for five or ten seconds, then release’ group of exercises.

Static stretches should form part of every 10 minute warm-up routine. Every major muscle group should be given a gentle pull, hold and relax. This helps improve the circulation and readies the muscles for more vigorous activity, while decreasing the risk of tears or tendon stretching.

Dynamic or ballistic stretches are more controversial, since they involve stretch with added momentum or even using weights. They are potentially harmful and that risk-factor is one of the major elements behind the controversy. At minimum, you should seek out a knowledgeable trainer before engaging in this form of flexibility training.

As one example, rest one knee on a ball and slowly rotate the ball away from the body, giving a very moderate bounce at the maximum point. Lunges, performed by moving one foot ahead, kneeling slightly with the back straight and bouncing gently, would be another.

PNF (Proprioceptive Neuromuscular Facilitation) involves a combination of passive and isometric exercise. Apart from having a fancy technical name and associated acronym, PNF actually has several useful features that should motivate individuals to investigate its value.

Performed properly, under the guidance of an experienced fitness professional or devoted amateur, PNF can maximize range of movement and best prepare the body for more strenuous exercise.

Several exercises involve using a partner. The muscle group you want to work is stretched under tension, then contracted for several seconds, and your partner applies resistance to inhibit movement.

For example, stretch your arms out and slowly move them behind you, then contract the biceps, triceps and shoulders. Have the partner gently pull your hands together a little past the 180 degree mark as you attempt to pull your arms back to 180 degrees.

As another example, lie on your back on a comfortable surface. Raise one leg vertically and have your partner grab your foot. Your partner then presses the foot gently backward until you feel tension on the hamstring (the muscle on the rear of your thigh). You then contract the muscles as you attempt to move your leg back down, with your partner resisting the movement.

These examples are to serve only to give a general idea of the exercises. PNF exercises should only be attempted after you have received proper, hands-on training. Done incorrectly they can lead to muscle sprain or joint damage.

Whatever your workout routine, be sure to precede it by good flexibility exercises. That will maximize your performance during the more strenuous part of the total workout.

Why?

Humans take in and use water for a number of important physiological functions. It provides a medium for cells and tissues. It makes possible the transport throughout the body of important elements or compounds like sodium and sugar not to mention forming part of the blood that moves them. It provides structural cohesion and lubrication between all parts. But there’s one more highly important function it helps perform: temperature control.

Homeostasis is the body’s ability to keep certain processes and factors in equilibrium, this is not too far from a central point. Body temperature is one key item among those. When body temperature gets too high, we experience fever and ultimately heat stroke. If it’s too low, we get chills. Both are signs that the body is in a less than ideal state.

One major reason is that all chemical reactions within the body have to take place within a very narrow range in terms of rate. Compounds have to be used and produced at just the right quantities within a certain time in order to proceed properly, or at all. Temperature, for very basic physical chemistry reasons, is a key factor in controlling that rate.

So how does sweat play a role in that?

Perspiring does not occur primarily in order to keep the amount of fluid in homeostasis – urination does that, along with breathing (though sweating plays a small part). But it has a huge effect on body temperature. As we exercise, chemical reactions speed up and mechanical motion is taking place. Both those produce more heat energy, which raises the internal temperature.

But the body is constantly seeking homeostasis – an equilibrium within a narrow range around a central point. For humans, that’s 98.6F/37C on average – a small deviation is within normal range. As we sweat, the excess heat energy is moved from inside the body to the outside, along the surface of the skin, carried along with the perspiration.

Outside the body a physical principle is at work – Newton’s Law of Cooling. Inside too, but never mind for now. Ignoring advanced mathematics, it says essentially that warmer bodies lose heat to cooler ones. We get cooler, the air gets a little warmer. Air molecules collide with the sweat molecules and pick up some of the heat energy they contain. That lowers the temperature of the sweat, lowering our temperature in the process (on the outside).

The net effect is to take excess heat on the inside and move it to the outside, somewhat like a home air conditioner or a car radiator. That helps keep the internal temperature at a constant 98.6F/37C.

That process takes place with breathing and just simple exposure. But sweating makes the process much more efficient, since water can carry a lot more heat than air does alone.

So, though it may have its unpleasant aspects, be thankful you perspire. After all, if you lacked sweat glands like your dog does, you’d look very silly panting. 

Exercising aids fitness in numerous ways, each involving one or more of those systems.

Increased physical activity causes the heart to work harder than at rest. That increases blood flow, floods tissues with fresh oxygen and removes cellular waste products.

Exercise causes the lungs to draw in extra oxygen to bathe the tissues and help power the heart. Exhalation removes carbon dioxide, a waste product of certain biochemical reactions.

Regular, moderate exercise helps raise HDL (High-Density Lipoprotein) cholesterol (the ‘good’ type). It helps regulate blood sugar levels and converts stored fat into sugars that are used to provide energy. That process also prevents obesity.

The other benefits of a regular fitness program are more obvious and usually among the more direct goals of most people who make the effort: increased muscle mass, toned legs, buttocks, arms, stomach and healthier looking skin. Along the way, the individual receives the added value of greater strength, improved balance, higher endurance and (often) a better frame of mind.

Different types of routines will emphasize one area more than another. Aerobic routines help the cardiovascular and pulmonary systems, weight lifting focuses on building muscle tone and mass, yoga and pilates helps balance, flexibility and muscular control. But each of these, and several more, help more than just the intended focus group. The body is an integrated system and improving one area almost always has beneficial consequences for others.

All those benefits, at least to a moderate degree, can be had for minimal daily effort. Moderate intensity activity for 30 minutes per day, at least five days per week, will go a long way toward optimizing fitness.

A brisk walk, taking the stairs up one or two flights, a short daily jog, jumping rope and many other simple activities can be carried out with no special equipment or training.

More intense activity, done properly, can raise that level even further. A vigorous tennis game, a few laps in the swimming pool, an hour on the treadmill or exercise bike, or any of a dozen others, can raise your fitness to a peak with only a moderate investment of time and money.

For the truly committed there are, of course, a thousand and one classes at the gym, and every conceivable kind of home fitness equipment to fit a variety of budgets. A daily routine using free weights, followed by a good jog around the park will keep all systems functioning well.

And, as Aristotle taught all those centuries ago, to function well is to live well.
