What should I do if I pull my back hard? Why is it sour to pull the lower back hard?

5 why is it sour to pull the waist hard? The main reasons are lactic acid accumulation+muscle fiber injury and inflammation.

1. The lower back is one of the most important parts of the hard map. Anaerobic exercise during hard stretching will make lactic acid accumulate in erector spinae of lower back, thus stimulating nerve endings and causing muscle soreness.

2. Hard pulling exercises the muscles of the lower back, leading to slight tearing and injury of the muscle fibers of the lower back, congestion and inflammation, leading to soreness.

It is normal to stretch the back pain of the lower back, because lactic acid is the inevitable product of anaerobic metabolism. Muscle enhancement requires muscle fiber damage, and then it can be increased and enhanced through recovery.
