How long should I foam roll my back each day?
Most physical therapists recommend one to two minutes per muscle group, spending about 5 to 10 minutes total per session. Roll slowly over each area and pause on tender spots for 20 to 30 seconds to allow the fascia to release. Overdoing it, especially with a firm roller, can increase inflammation and soreness rather than reduce it.
