Stretching exercise is needed before and after exercise. Stretching before exercise can reduce muscle strain, and stretching after exercise can help relax muscles and reduce muscle soreness the next day. If you want to build muscles, you must extend each movement to more than 10 second. Some personal behaviors should be extended to more than 20 seconds. How to determine the details? If you can complete as many operations as possible in 10 seconds, you must keep it as long as possible. If you find it difficult to continue, please try 10 seconds or more. Every movement is stretched out. We need very beautiful muscles, and we will form a balanced curve.

We are still very fragile in sports, and stretching can help us reduce this kind of injury. Because the body often stretches after exercise, the flexibility is effectively improved. Because the flexibility is improved, it is necessary to reduce the chance of injury in sports. If you don't want to get hurt, you must carry out complete stretching training to reduce the harm to your body due to improper exercise. Stretching and relaxing after training can help our muscles recover, because in the process of stretching and relaxing, our muscles are not only well relaxed.

And in the process of stretching and relaxing, our muscles will also open the door to nutrient absorption, so that our muscles can better absorb nutrients and make our muscles recover better. After training, there will be a lot of lactic acid in muscles, which is also the main reason why some people feel muscle pain. Stretching will accelerate the decomposition of lactic acid, and it will feel very painful at that time, but it will recover well after stretching and will not affect the next training. After training, you won't feel anything if you don't stretch for a short time. If you don't stretch for a long time, your muscles will get tighter and tighter, your muscle elasticity will get worse and worse, and your ligaments will get tighter and tighter. Regular stretching after exercise helps to improve the flexibility of our body. It can make our bodies softer and more flexible. Keep stretching for a long time, and our sports meeting will become easier.
