FST – Fascial Stretch Therapy What is Fascial Stretch Therapy? Fascial Stretch Therapy is a stretch technique specifically used to release the knots and trigger points that build up in the fascial nets. In this depiction, the left side is what would be best for you, but most of the time, our muscles are similar to the right image, full of knots and scar tissue build up.Fascia is the glue-like material in our bodies that holds all of our cells and muscles together. Sometimes, there is an abundance of fascia, which develops into trigger points, knots, scar tissue. This causes us to experience pain, discomfort, and could even start to restrict movement. This tends to frequently occur in the fascia of muscles and joint capsules. This is one of many ways to stretch the lateral hamstring, the glutes, and the iliotibial band.By cradling both legs and supporting the sacrum, this will stretch the low back.
