After every exercise, everyone will feel very tired, just want to lie down and rest, and don't want to move. However, although I am very tired, I still need to do some necessary stretching exercises.

But many people often don't pay enough attention to stretching exercise, and think stretching exercise is a waste of time.

Many people who exercise to lose weight will encounter such troubles: the amount of exercise every day is not small, but the effect of losing weight and shaping is not obvious. The legs didn't get longer and the waist didn't get thinner. Even they found their limbs getting stronger and stronger, and their bodies began to grow horizontally.

This is because there is no stretching exercise after exercise. If you don't stretch after exercise, your muscles won't relax, and the effect of reducing fat will get worse. Your muscles will become stiff and tight, your calves will become thicker and thicker, and your body will be miserable!

Active stretching is a link to be carried out after exercise, which refers to stretching muscles along the direction of muscle fibers by using their own strength or weight. When the muscle is stretched to a certain tension, hold 10- 15 seconds, relax, and then repeat 2-3 times. Stretch slowly, don't let the muscles feel pain, cooperate with breathing, and further stretch the muscles when exhaling.

Before stretching, let's learn how muscles contract and move.

The smallest unit of muscle is myofilament, and muscle movement means that myofilament slides on thick muscle fibers.

When relaxing, the middle interval becomes longer and the muscles become softer and smaller; When contracting, the middle distance becomes shorter, indicating that the muscles are hard, tight and thick.

Therefore, in order to slim down, you must do stretching exercises.

Don't underestimate stretching, body shaping is mainly achieved by stretching muscles.

Some people complain that their muscles are not beautiful and their bodies are beautiful? Work hard? Not flexible enough, that is, they lack effective stretching. Stretching exercise after training can play a role in shaping, relieving muscle soreness and relaxing bones and muscles.

There are many stretching exercises. However, in stretching practice, it should be noted that it is difficult to maintain the active stretching posture of 15 seconds under normal circumstances, so it is enough to maintain the general stretching action of 10 seconds, and it does not take too long.
