The muscle produces bluish purple, indicating that the muscle has congestion and poor blood circulation. Soreness means that there is a lot of lactic acid in the muscle that is not excreted. In this case, you should give your muscles a full rest and wait for your body to excrete lactic acid before exercising.

Physical exercise is not required to compete hard, but to exercise in the most scientific way. Many sports can't be exercised every day. You must give your body enough rest time. Continuous exercise every day will make your body never rest and can't recover tired muscles. The consequence is that even if you practice harder and harder, exercise will have no effect. The body doesn't lie.
