Many people believe that when specific muscles are exercised, the fatty tissues (組織) in the immediate area are burned up. The truth is that exercise burns fat from all over the body and not from one specific area. Of course, if you reduce the fat throughout your body, you will certainly see results around your waist too.Some people believe that you need to exercise twice a week in order to keep a sufficient level of physical fitness. However, studies directed by American scientists show that unexercised muscles lose their strength very quickly. Within 48 to 72 hours, you must use the muscles again to reestablish (重建) the good physical effects. And what does that mean to you? American scientists concluded that while daily exercise is most helpful, exercising every other day or three days a week will keep a sufficient level of physical fitness.Is it true that you burn more calories running one mile than walking the same distance?

Of course, if you run rather than walk for 30 minutes, you will cover more distance, and therefore burn more calories.If your breathing doesn’t return to normal within 5 minutes after you finish exercising, you have exercised too much. Five minutes or so after exercising, your breathing should be normal, your heart shouldn’t be beating loudly, and you shouldn’t be tired. 53.
