If you haven’t used one before, foam rollers hurt, but in a good muscle-tightness-releasing way, like a good massage. You can use it to warm up your muscle before a workout, or stretch post-workout to reduce soreness. This foam roller is just $20 today and has a near-perfect 4.9 out of 5 star rating after 156 reviews.
