Many people like to sweat when they exercise. It seems that only when they are sweating can they feel full of exercise, but in fact it won't have any effect, it will only make you exercise too much and lose a lot of water, leading to sports injuries such as cramps and lack of water. Therefore, once you sweat during exercise, you should replenish water in time and adjust the intensity appropriately, rest for a few minutes and drink two mouthfuls of water.

2. Select only one sport:

Many people like to do only one exercise, such as running or riding an exercise bike, thinking that as long as they persist for a long time, the effect will be obvious. In fact, comprehensive exercise needs several kinds of exercises. "Walking 1 mile (about 1.6 km) can burn 100 calories; But in the same 20 minutes, if you do weight-bearing exercise on the equipment, you can burn 300 to 400 calories. " Emilhoff said. Strength training can help you keep muscle shape and delay muscle relaxation brought by age, so it is best to combine aerobic exercise with weight training. "Try running, playing ball, sit-ups and lifting weights."

3. Exercise while flipping through magazines:

Some people often read magazines while pedaling bicycles, thinking that they can completely relax. You know, you can't do two things at once. Reading magazines means that you can't pay attention to the exercise you are doing at the same time. If you have to do something else to make exercise less boring, you can listen to music because it doesn't require concentration like reading.

4. Exercise on an empty stomach:

Many people who get up in the morning or get off work will exercise on an empty stomach. "Doing exercise on an empty stomach is like driving a tank without oil. Your body needs energy to keep running. " Some healthy snacks, such as oatmeal or bananas, can be easily digested and provide extra energy for your next exercise. Especially when you exercise in the morning, you can't eat on an empty stomach, because at night, your stomach is empty and your calories have been consumed. You need to add some fuel to your body.
