A girlfriend around me tried to lose weight by running, but finally found that her calf was not thinner but thicker, and she felt stiff to the touch and gained weight. This is actually because the calf muscles increase and appear thick. Because in the process of exercise, we constantly put pressure on the body tissue, causing muscle fibers to tear, and then repair and recombine to thicken. Moreover, after training, the glycogen stored in our body muscles increases, which also increases the water in muscle reserves, thus increasing muscles.

The principle of muscle is used to advance and retreat.

We must first understand the principle of muscle growth. Muscle does not grow because of exercise, but destroys your muscle cells through a lot of high-intensity training, and then recovers excessively by supplementing protein. Make muscle fibers bigger and thicker. To put it simply, you don't have long muscles during training, and you can increase your muscles by supplementing protein during rest. When exercising, you must pay attention to planning and give your muscles enough rest time, otherwise you will be easily injured.

The benefits of regular exercise

I have a friend with a serious hunchback. Later, after fitness, I realized that it was because there were too few back muscles. Later, my friend exercised his back muscles, and now he seldom hunches. Moreover, people who see him now feel different from the past. They are full of energy, with higher and wider shoulders, which is completely different from the decadent appearance before. Therefore, fitness can not only change people's mental outlook, but also make people happy and increase their self-confidence. Moreover, it is easy to develop good eating habits and quit many bad snacks after fitness.

Exercise sharpens people's will.

The benefits of exercise can not only change the body shape and appearance, but also hone people's will. Improve self-tolerance and self-confidence, and make yourself more and more optimistic and open-minded. There is only one life, and a healthy body is what we pursue all our lives. Therefore, the greatest effect of exercise on people is to get healthy.
