The best thing you can do is to improve blood flow to the affected muscle groups by moving your body, sauna sessions, foam rolling, percussion therapy or even electric muscle stimulation. Also, don’t forget about the importance of sleep for your recovery process. During certain stages of sleep (slow-wave and REM sleep), the body releases hormones, such as testosterone and human growth hormone, that play important factors in muscle recovery and growth.  So make sure you get a good night’s sleep before and after intense workouts or competitions.
