Honestly. The combo of this and nerve flossing got me back to training after fracturing three vertebrae. It helps the QL muscles get strong in all the ranges they need to move in, pulls blood into the area as it helps a muscle relax. The more blood into the muscle the less tight it has to be. And it’s a cheeky nerve flossing aswell. Our QL muscles should be huge. Think another ass on top of your actual ass 😂 and you can build up to heavy-ish weight pretty quick. Ideally you’ll build up to half your bodyweight on each side. Try it and let me know what you think!
