|Exercise makes you slim
Exercise does not make you slim. It can assist in losing weight by increasing calorie needs, but it cannot cause you to lose weight on its own except in extreme situations. Combined with a low-calorie diet, exercise can help you get fit.
A little exercise is better than nothing
Although something is better than nothing, it isn't better by much. Sporadic exercise doesn't accomplish much in the way of muscle development or increase your metabolism. It is better to work out 15 minutes every day than run for an hour and a half on Saturday.
Exercise burns fat
This couldn't be farther from the truth. Exercise builds muscle. It doesn't burn fat. In fact, a build-up of muscle in certain areas can actually make you look heavier (e.g. the thighs). Moderate exercise combined with a good diet will build a lean, healthy body.
If a little is good, a lot must be great
Wrong again. Many women hit their workouts with gusto hoping to fight fat thighs. Most of the time, this results in an increase in thigh size. The key is to exercise your entire body, maintain a steady schedule, and develop healthy eating habits.
Exercise makes you tired
Exercise actually energizes you. Moderate, regular exercise gets muscles in shape and releases good chemicals in the body and brain. A regular routine of exercise will actually give you more energy to deal with kids, housework, your job, and your love life.
Exercise takes too much time
A well-developed exercise routine requires only 15-20 minutes each day to develop a healthier heart, improve muscle tone, and get all-over body conditioning benefits. If you add a short walk (instead of parking close to the store), take the stairs (instead of an elevator), and incorporate some bending and stretching into your housework, you can easily add another 5 or 10 minutes of exercise to your day without any impact on your hectic schedule.
