Physical Fitness

Physical fitness is today’s hot topic. And wherever you turn, you hear something new. But is it all true?

The more you sweat, the more fat you burn. This myth has encouraged people to work out in extreme heat or wear layers of clothes or rubber or plastic weight-loss suits in the hope of sweating fat off. Unfortunately, it’s water they’re losing, not fat. When you first begin to exercise, you burn carbohydrates or sugars. To burn the fat, plan on working out at least 40 minutes.

No pains, no gains. Many people tend to overdo (過度)their exercise programs looking for quick results. Doing so, however, may result in your injury or sore (疼痛的)muscles. Your best bet is to start any exercise program slowly and gradually increase the workout. This gives people a good beginning without the pain or injury.

Exercise increases appetite. This is true for hard or intense (劇烈的) exercise that lasts for 60 minutes or longer. Gentle exercise that is less than 60 minutes, however, will probably reduce your appetite for one to two hours. Exercise always lowers blood sugar.

You can get fit in 10 minutes a week. This and similar claims are common, but untrue. There are no shortcuts to getting fit. Becoming fit takes work and the general rule is 20 minutes of aerobic activity(有氧運動) three times a week. Consistency is the key. If you stop working out, your muscles will turn to fat. If you decrease your activity and continue to eat the same or more, you may gain back the fat that you worked so hard to lose. It’s not, however, because your muscles turned to fat. Muscles may atrophy (萎縮), but they won’t turn to fat. Muscle is muscle and fat is fat.
