Exercising is one of the most important thing we can do for our bodies.
Eating good food and drinking many water are not enough to make us stronger and healthyer. A person should exercise at least three times a week for an hour or more. This is especially important if a person is too heavily.
If they want to lose weigh, they may have to exercise five to six times a week. Running and walking are good with your heart. You will feel really relaxing after you finish the exercise. When you run, you have to use your legs and arms. This make your legs stronger. If you never exercise in before, it is best to start slowly.
It is also a good idea chat with your doctor before you start exercising.
