Muscle ache is caused by insufficient blood oxygen supply during exercise, which produces a large amount of lactic acid and deposits in some muscles. Here are some ways to relieve muscle soreness:

1. Active recovery method: simple low-intensity aerobic exercise after training can increase blood flow and relieve muscle pain. After intensive training and competition, this method can effectively calm you down.

2. Rest recovery method: stop exercising, let lactic acid be consumed naturally, and restore the physical quality on weekdays. The time is about five days.

3. Stretch recovery method: Choose aerobic exercise or stretching instead of previous exercise after muscle aches. During exercise, the body will accelerate the decomposition of lactic acid and generate energy.
