The first, and easiest, change to make in your quest to fitness is to add “lifestyle physical activity” to your day. This means being more physically active as you carry out your usual daily activities. You can:
1) Park in a far-away spot and briskly walk to your destination
2) Take the stairs instead of an elevator
3) Play real games with the kids instead of computer games
4) Go golfing, bowling or dancing for fun instead of a movie
5) Take a walk during a morning or afternoon break.
Making these changes is an easy way to improve heart and respiratory fitness, mood, and muscular fitness and reduce body fat. However, for women who need to make more dramatic gains in fitness or would like to lose weight, a more formal exercise program, in addition to lifestyle physical activity with proper professional guidance is necessary.
A good program should address the five components of fitness by including:
1) Aerobic activities, which involve using the large muscles of your body in a rhythmical, continuous activity, improve cardiovascular conditioning and help reduce body fat. Aerobic exercises include walking, jogging, bicycling, swimming and aerobics or exercise classes or videos.
2) Strength training, such as weight lifting, improves muscular strength and endurance, helps maintain bone density, and raises metabolism, causing you to burn more calories.
3) Stretching exercises, which include slow, gentle movements that elongate your muscles, improve flexibility.
How Much Is Enough?
One of the most common questions is, “How much do I need to exercise?” I recommend that healthy women do some sort of aerobic exercise on most or all days of the week for 20 to 30 minutes. These minutes can be accumulated-10min of an aerobics video in the morning and 10 min of brisk walking in the evening, for example. Intermittent exercise (intermittently increasing the heart rate) can be part of a good weight-loss strategy because your metabolism is elevated following each bout of exercise.
If you have been inactive, you need to work up slowly to this amount. Start with five or 10 minutes-or whatever you’re comfortable with-every other day, and add one minute every other session. If you do too much too soon, you can become injured, fatigued and discouraged. At the top end, I would recommend experienced, recreational exercisers to do no more than 200 minutes per week of aerobic exercise with no more than 60 minutes per session to avoid overstressing the body.
Similarly, don’t overdo strength training. Start slowly, with lighter weights, and work up to heavier weights and more repetitions or sets of repetitions. You don’t need to strength train more than three days per week; and always wait at least 48 hours before exercising the same muscle group to give those muscles adequate time to recover between sessions.
Stretching and flexibility exercises should be done for 10 to 12 minutes three times a week. They can follow an exercise session. Some lighter stretches can even be done at your desk or while you watch TV. Examples of stretching exercises include shoulder or arm circles. There are also a number of stretches specifically targeted to arm, back, chest, thigh and calf muscles.
How Hard Should You Work?
“How hard do I need to exercise?” As you work on increasing the length of your exercise sessions, you also need to work on increasing their intensity. Low-intensity aerobic exercise, like housework, gardening and walking the dog, provides a great deal of general health benefits, but to truly enhance fitness, especially if weight loss is one of your goals, you need to up the ante and exercise at a moderate or higher intensity with vigorous activities like brisk walking or jogging, singles tennis, aerobics classes or cycling.
The intensity of your strength training exercise will increase over time as well. Don’t strain to do more, but slowly work your way up to heavier weights or more repetitions. The last two reps should be difficult to achieve, because the idea is for the muscle to be challenged; if the last two are no longer difficult, it’s time to move to heavier weights. You will be amazed at how much more you can do after even a few weeks. Generally, select a weight that you can lift only 10-15 times and perform two sets of each exercise. Gradually progress to a weight that you can only lift six to 10 times and perform two to three sets.
What kind of exercise?
“What should I do?” The key to sticking with an exercise program is choosing activities you enjoy, and there are many to choose from. The best way to start is to engage a personal trainer to develop a plan for you and show you correct and safe ways to use the equipments such as weight machines, free weights or resistance equipment like specially made rubber bands or a weighted vest, and you can train at a health club or at home. In any case, if you don’t use the proper form, you can injure yourself, so you need to learn how to use the equipment from a personal trainer.
Strength training is important to women of all ages. In young women, it can set the stage for a lifetime of stronger bones. Research shows that women start to lose muscle strength as early as age 25. For these women, strength training can help slow or reverse the natural process of muscle degeneration. And studies have shown that older women who strength train not only maintain bone density but have a much lower risk of hip fractures, due in part to the improvement in dynamic balance that often accompanies stronger muscles.
Functional or core strength training - This type of training helps strengthen the muscles of the back, trunk, abdomen, and pelvis. The idea is to strengthen these muscles first in the “movement chain” to prevent injury and to provide a solid, stable base, so that the muscles further down the chain-the legs and arms-have a stable base supporting them and will also be strengthened safely and more efficiently. So, for instance, rather than strengthening your legs with hamstring curls and leg extensions-which don’t have much application in real life-you do squats, step-ups or walking lunges that challenge your entire body and improve dynamic balance while strengthening your legs and thigh muscles.
Aerobic exercise - The options are many and varied. Some of the more popular choices include the following:
1) Brisk walking is the most popular aerobic exercise among women and is appropriate for women of all ages. Walking at a swift pace burns almost as many calories as running or jogging for the same distance, and poses less risk for injury. If you are a beginning walker, choose a level surface. Gradually increase your pace until you can do one 1.5km in about 15 minutes. To intensify the exercise, add hills and varied terrain to your course. You can also use hand weights of one to three pounds, but avoid ankle weights as they can cause injury.
2) Jogging burns more calories in less time and is as simple and convenient as walking, but it is too strenuous for some and may cause joint injuries. If you are a beginner, alternate walking and jogging for the first three or four weeks. Then gradually increase the jogging portion until you can comfortably run for the entire workout. Remember not to exceed your target heart rate.
3) Group fitness classes offer variety, music and choreography, and some women prefer the extra motivation an instructor provides. Start with beginner classes, and watch the instructor carefully for proper foot placement and body alignment to avoid injury, especially to your knees.
Don’t forget to take particular care of your feet proper shoes are crucial to successful, injury-free physical activities. Shoes should provide sufficient cushioning and shock absorption to compensate for pressure on the foot many times greater than found in walking. They must also have good medial-lateral stability. Impact forces from physical activities can reach up to six times your own body weight, which is transmitted to each of the 26 bones in the foot. Because of the many side-to-side motions, shoes need an arch design that will compensate for these forces, and sufficiently thick upper leather or strap support to provide forefoot stability and prevent slippage of the foot and lateral shoe “breakup.” Make sure shoes have a toe box that is high enough to prevent irritation of toes and nails. Major shoe companies today have designed special shoes for physical activities, which provide the necessary arch and side support; they also have soles that allow for the twisting and turning of any exercise regimen.
Swimming is an ideal exercise for pregnant women and those with physical limitations such as musculoskeletal problems and asthma. However, swimming does not raise the heart rate quite as much as other aerobic exercises because humans are equipped with a reflex that causes the heart to slow down when immersed in water. For swimming, use a heart rate target of 75 percent of your maximum minus 12 beats per minute. For those whose only option is swimming, however, it is certainly better than remaining inactive. If you have arthritis, try to find a facility with a warm water pool.
Flexibility training - don’t skip these exercises, because they are beneficial in helping prevent cramps, stiffness and injuries. They also ensure a wide range of motion, particularly important as women age. Two flexibility/stretching regimes are popular enough now that you should be able to find a class for either that fits your needs and schedule.
Pilates- This 70-year-old, low-impact exercise technique was first developed by German immigrant Joseph Pilates. It has recently experienced an upsurge in popularity, in part because of the greater popularity of yoga, but also because numerous celebrities have begun using it for toning and stretching. Some Pilates programs uses machines with pulleys, springs and ropes which gently stretch all parts of your body with mild resistance; others use a series of floor exercises. It is also called “The Movement,” and much of its focus is on strengthening back and abdominal muscles, increasing flexibility and building core strength.
Exercising when pregnant
Exercising when you’re pregnant can help you achieve better posture, less back pain, less stress, better digestion, more energy, an easier delivery, and less “postpartum belly.” It can also prevent or control gestational diabetes and reduce the chance of complications during delivery. If you’ve exercised throughout your pregnancy, you will be rewarded with increased strength, flexibility, and stamina during labor and delivery, as well as a faster recovery.
Be sure to consult with your OB/GYN about your exercise routine. If you were already active before becoming pregnant, you should be able to continue, within reason. If you are new to exercise, be sure to start slowly and do not overdo. Low-intensity or low-impact cardiovascular exercise like walking, swimming, low-impact aerobics classes, or special exercise classes for pregnant women are best. You can engage in these activities three to four times per week for about 30 minutes per session. Ask your OB/GYN about a target heart rate; keeping it below 140 beats per minute is recommended. It’s critical that you keep your body cool and well-hydrated (drink lots of water) during exercise. Don’t forget to warm up and cool down.
Strength training during pregnancy can also be beneficial in building stamina and strengthening muscles and bones. Use lighter weights or resistance because heavier weights increase your chances of injury. Remember to breathe normally. Keep these pointers in mind:
1) Don’t do exercises performed while lying on your back after 20 weeks
2) Avoid deep knee bends, abdominal exercises while lying down, double leg raises and straight-leg toe touches (your ligaments are more prone to injury during pregnancy)
3) Because overheating can be dangerous to your baby, don’t exercise in hot, humid weather or wear excessive clothing
4) Always drink plenty of liquids and stop and consult your health care professional if any unusual symptoms appear, including pain, bleeding, dizziness, shortness of breath, irregular heartbeat or difficulty walking
Exercising with chronic conditions
Today, exercise is often recommended as a management strategy for many chronic medical conditions. Of course, a thorough discussion of exercise with your healthcare professional is imperative prior to beginning any kind of program.
For example, for someone who suffer from osteoporosis, a bone disease that causes bones to thin and weaken, exercise is highly recommended. A carefully designed exercise program can help protect your bones and retard development of the disease. Weight training, in particular, helps counter the effects of osteoporosis by stimulating bone formation. Begin with a weight that you can lift 10-15 times, and perform one to three sets. Progress to two to three sets of a weight that can be lifted only six to 10 times (up to 80 percent of your maximum). Walking, jogging and aerobics classes also help build bones. Bicycling and swimming, however, don’t stimulate bone formation in the hips because you do not bear your full body weight on your feet. Flexibility exercises enhance your posture and increase your balance, making you less susceptible to dangerous falls.
Exercise also is extremely helpful if you have diabetes. Diabetics who are physically active have fewer diabetic complications. Exercise can lower your blood sugar level, helping reduce or eliminate the need for insulin. I would recommend a combination of aerobic activity, strength training and stretching exercising three to five times per week for 20 to 40 minutes each time. Always check your blood sugar level prior to exercise; if it’s lower than 70 mg/dl or you are exercising more than one hour after a meal, you may need to decrease your insulin or have a light snack beforehand to avoid having your blood glucose level drop too low. Always have a fast-acting sugar source with you in case you do have a reaction, and wear a medical alert identification bracelet or necklace. There are several other precautions you need to be aware of, so be sure to consult your health care professional first.
For those at risk of developing heart disease-if you have a family history of heart disease, are overweight, smoke or have high cholesterol, diabetes or high blood pressure, for example-exercise is crucial. A lack of physical activity itself is now clearly the risk factor for cardiovascular disease. Studies have shown that people who are physically inactive are from 1.5 to 2.4 times more likely to develop heart disease-a risk as great as high cholesterol, high blood pressure and cigarette smoking.
Even low-to-moderate intensity activities such as pleasure walking, climbing stairs, gardening, yard work, moderate-to-heavy housework or dancing can bring benefits when done for as little as 30 minutes a day. More vigorous aerobic activities such as brisk walking, running, group fitness classes, swimming, bicycling, roller-skating and jumping rope-done three or four times a week for 30 to 60 minutes-are best for improving the fitness of the heart and lungs. If you already have heart disease, you can exercise safely as long as you work out under medical supervision and carefully monitor warning symptoms. Strenuous physical exertion is never recommended for people who suffer from congestive heart failure, unstable angina, chest pain, significant aortic valve disease or aortic aneurysm.
Some of these conditions, however, such as congestive heart failure, might benefit from mild or moderate exercise under controlled situations. Exercise also is beneficial for and can help control obesity, high cholesterol, high blood pressure, back pain and may improve the symptoms of some neurological and emotional disorders. It also has been shown to help prevent certain types of cancer.
