First of all, every girl must have such doubts when she is exercising. "Why does running grow calf muscles? How to exercise so as not to grow muscles? " One problem that most girls ignore is stretching after fitness.
In fact, stretching exercise after fitness (running) is very necessary, which can relax leg muscles, and will not lead to lateral growth of leg muscles, but will lengthen longitudinally, and may even grow taller.
Not only the leg stretching after fitness, but also the samples before fitness. Everyone who goes swimming should know that every swimming coach will let everyone do physical expansion before going into the water. In fact, doing that is doing stretching exercise; Everyone has basically received nine-year compulsory education. There is a class called physical education class. The PE teacher will let us do aerobics after the bell rings and before the formal class. In fact, the role of this aerobics is the same as stretching.
Whether it is the outward bound training before swimming or the aerobics before physical education class, the purpose is to protect our joints and muscles from injury. If we don't stretch before doing exercise, we are likely to have symptoms such as muscle strain and cramp. If the treatment is not timely, it will affect a lifetime.
When our muscles are strained or cramped, let's stop all existing exercises at once. When there is a fitness instructor nearby, you should ask for help in time. After that, we'd better go to the hospital or clinic to get some ointment.
Therefore, in front of any exercise, stretching should be carried out, not only to keep our muscles elastic during fitness.
So stretching is really important, don't forget.
