Foam rollers are inexpensive, easy to use and take up little space, so it’s no wonder they’re now popular in health clubs, physical therapists’ offices, and home gyms. What’s more, they’re incredibly effective for working out "knots" or trigger points in your muscles.
Foam rollers are often used by therapists and athletes to mimic myofascial release treatments, which are typically used to help reduce muscle immobility and pain.
Its benefits are often compared to getting a massage, because as you roll on it, fibrous tissue is broken down and circulation is boosted, helping to relieve tension and pain.
Form and technique matter when using a foam roller, just as they do with other exercise techniques. Many people wait to use a foam roller until they feel a tight spot in a muscle, then simply "roll" it out. This might provide you with some relief, but it likely won’t give you the full benefits that foam rolling has to offer.
