1 The warm-up before exercise was not done well, which led to the limbs passively accepting strenuous exercise.
2 excessive and unscientific exercise, including unscientific sequence and measurement, leads to local position overload practice. (For example, if you want to practice upper limb strength, you have been practicing upper limbs, ignoring the practice of lower limbs, resulting in a cold and a hot body. )
3 accumulation of fatigue. Because of the heavy exercise, I didn't do enough relaxation exercise.
Suggestion:
Make a scientific and comprehensive fitness plan and practice according to the plan. Correctly understand your body's acceptance ability, don't overload exercise, and control the measurement and intensity of exercise through the data of morning pulse and instantaneous pulse during exercise, so as not to cause fatigue accumulation as much as possible. Pay attention to a small amount of hydration during exercise, properly supplement nutrition after exercise, and eat as much fruit as possible to help take away the residual lactic acid in the body. . .
