After strenuous exercise, especially after strenuous exercise without warm-up, a large amount of lactic acid will gather in the limbs. Because the normal pH of the body is balanced, when a large amount of acidic lactic acid is produced, it will cause muscle aches, no exertion and other feelings, which will be automatically eliminated within a few days after massage.

Don't exercise excessively at the beginning, but step by step. Because I haven't received such intensive training before, I must gradually increase the amount of exercise from a small age to adapt my body. And after each exercise, do appropriate relaxation exercises to relax the tense muscles.

In addition, if you are in this situation now, take a rest 1 or 2 days to get rid of your muscles' soreness before training. You can properly spray some Yunnan Baiyao spray, or apply some iron wine such as winding oil, or relax tight muscles with some massagers, take a hot bath, and relax your muscles with your fists, which can shorten the recovery time.

I hope I can help you.
