1, muscle pain intensifies. Generally speaking, one or several days after fitness training, our muscles will feel more or less pain. If we don't do necessary muscle stretching after fitness training, our muscles will not be able to return to normal from the congestion state during training, thus aggravating our muscle pain.

2. The chance of self-injury will increase. After we finish muscle strengthening training, our muscles are likely to be in a certain degree of tension. If you don't stretch at this time, then this tight state will continue.

Continuous muscle tension is not a good thing for us. If at this time, we suddenly let the muscles exert their strength, then the muscles are likely to cramp and even cause muscle damage.

4. Muscles will become harder and harder, and their flexibility will become worse and worse. What we need to know is that stretching plays a very important role in making our muscles more malleable, that is, making their muscles more elastic. If you don't stretch your muscles after fitness training, they are likely to become harder and harder, and their ductility and flexibility will become worse and worse.
