Melissa Hatton, NASM Elite Trainer, Administration, answeredYou can use the foam roller for self-myofascial release everyday. This is a great way to release tension in tight muscles. On days when you do workout, it is best to perform SMR (foam rolling) both before your workout, as part of your warm up, and after your workout, as part of your cool down/stretching.

Ideally, use the foam roller for self-massage at least two times (in warm-up and cool down) everyday you workout. Any additional foam rolling beyond workout days is encouraged!
