@sundance6 What you experienced is cupping which is a way to stretch the fascia and it is like grabbing your skin and pulling. That doesn't stretch the fascia in a way to activate the fascial net in the entire body. A person who is trained in the John Barnes methods (the guy who invented this) will have certifications like "expert level" and you can look up a lot of practitioners on his website that lists their credentials. myofascialrelease.com The provider search is here. https://myofascialrelease.com/find-a-therapist/ People might be using the terminology, but not really doing the proper procedure.

The right way to do it is the therapist sinks in with their hands and pushes your skin different direction to feel where the resistance is. Often they first push and hold it the direction with easier movement to get things moving, and then shift and change direction. It is like kneading bread dough in extreme slow motion where you push against the barrier to create a shearing motion. You just hold that and wait and adjust as you go and the fascia starts to slide and release. A good PT can feel the restrictions with their hands and understand where that connects in your body. If they can't do that, they are guessing. MFR done correctly gives great results. It has helped me a lot, and my PT is expert level John Barnes trained.
