Not stretching after fitness is like not doing homework or reviewing after class. You may forget what you learned today the next day. Stretching is as important as warming up before fitness and can't be ignored. Many people think that they will be tired after doing exercise, so they seldom stretch again. It is better to go back to wash and rest early, there is no need to feel too time-consuming. First of all, this mentality is wrong. So what will happen if you don't stretch after fitness?

1. will cause muscle necrosis and lose elasticity.

Many people say that muscles should be hard, but they are not. Muscle is actually a very elastic substance. Of course, it will harden after hard work. The dead muscle we are talking about is the kind of muscle that can't be pinched. If you don't stretch and relax your muscles after fitness training, you will lose elasticity, become stiff, reduce the flexibility of your body, and become stiff and mechanized, which is not good news for a sports enthusiast.

It is also very important that stretching can make our muscles slim, which is also a way to prevent muscle accumulation. Many girls say that the hind legs will thicken after exercise, because you usually don't pay attention to stretching and relaxing, and your muscles pile up together, which naturally doesn't look good.

2. Not stretching will affect our recovery.

After fitness, our muscles will have a lot of lactic acid accumulation and feel very sore. Of course, weakness is also a sign of fatigue. Stretching and relaxing will let lactic acid out, which will further relieve our body's fatigue and is also a way to make our muscles recover excessively. Muscle recovery speed is accelerated, and the next day it won't be so painful! It doesn't mean that the more sour the muscles are the better the next day. There is no such thing. The more sore you are, the more you are not good enough. You didn't stretch, you didn't repair your muscles well! Not stretching directly affects the fitness plan and life of the next day!

3. Muscles are inelastic and easily injured.

My muscles are prone to strain when they lack elasticity. This is my personal experience. I don't like stretching and relaxing after exercise. When I am too tired, I always want to go back and have a good rest. The muscles were stiff, and the weight was not very heavy when squatting, which directly strained the groin. There are still some problems. If I don't warm up, I will feel something lying in a squat, which is very uncomfortable. This is the result of not stretching for a long time. Ordinary strain is nothing. If the weight is heavy, it will be a great harm, and we will regret it all our lives. Therefore, full stretching after fitness is also a kind of maintenance for yourself. Cars have to be maintained, not to mention ourselves.

Fitness is more than just going up and pressing the iron twice. Warm-up, training, stretching and relaxation are all systematic and indispensable. Don't ignore every link!
