In recent years，plank exercise(平板支撑)has become more and more popular. Doing plank exercise often may bring you lots of advantages. It's easy to find a proper place to do plank exercise. You can even do it with a chair! But you should use a stable(稳固的)chair to make sure that you stay safe. It is dangerous if the chair moves during exercise.
Doing plank exercise as a daily home exercise before or after school will not only speed up your metabolism(新陈代谢)，but also keep your metabolic rate(速率)high all day long. Doing it often will make you burn lots of calories(卡路里). This is especially useful if you have to sit in the classroom for hours every day. A high metabolic rate will help you lose weight and keep in good shape.
Have you ever tried standing on one leg? You couldn't stand straight for more than a minute，right? It's because your muscles(肌肉)aren't strong enough to give you the balance you need. Doing plank exercise often will improve your balance. Stronger muscles will also help you stand straighter for longer.
▲ Just think about it: You are sitting all day long. Your muscles get tired，and your legs get heavy. Plank exercise will relax the muscle groups that may cause stress in the body.
As a result，it can make you feel better and happier.
Considering all the advantages of plank exercise，will you make it part of your everyday life?
