Foam rolling or Self-Myofascial Release is a flexibility technique that focuses on neural and fascial systems in the body. It concentrates on alleviating myofascial trigger points and areas of hyper-irritability located within a band of muscle. This form of stretching incorporates the concept of autogenic inhibition to improve self tissue extensibility. -NASM CES definition
I use foam rolling and other forms of SMR with most my clients. There are contraindictions and a precise method, so make sure you fully understand the concept before “rolling” anyone. I often see foam rolling overused and in ways that could cause serious damage, espcially on the back areas.
