1, push-up exercise requirements: keep your hands close to your abdomen, keep your body on a plane, support fast and slow, and don't collapse, each group 10-20 times.

2. Push-up exercise requirements: When doing push-ups, don't touch the ground, stand in the abdomen and hold up at the same time. Other requirements are the same as push-ups, each group 10-20 times.

3. Every time you practice, let the muscles fully stretch and lengthen first, and then contract, with a large range of movements. Because muscle fibers can increase the contraction force after being stretched, and at the same time, they can maintain good elasticity and contraction speed of muscles. After strength exercises, muscles are often congested and swollen badly.

4. At this time, you should do some stretching exercises contrary to strength exercises, or do some massage and shaking to fully relax your muscles. This can not only accelerate the elimination of fatigue and promote recovery, but also prevent the joint flexibility from decreasing due to strength training, and also help to maintain good elasticity and contraction speed of muscles.
