First of all, training methods should be reasonable, sleep time should be sufficient, avoid alcohol and tobacco, eat less food with high sugar content, and supplement protein more. Protein is rarely used as a functional substance. After exercise, body muscles begin to grow. This process needs a lot of high-quality protein. In addition to daily dietary supplements, you can also supplement it by eating protein powder. Protein powder can be found in physical stores such as PQfitness Online.
