I’ve accumulate so much of this kind of stuff over the years. I really do use them but some for sure more than others. The lacrosse ball is a game changer for real though. ~ A lacrosse ball is an effective, inexpensive tool for self-myofascial release (SMR) and trigger point therapy, using body weight and gravity to apply deep pressure to tight muscles, knots, and connective tissues. By rolling or holding the ball on tender areas (such as glutes, back, or feet) for 30–60 seconds, you can break up adhesion, increase blood flow, and relieve pain. ~ Gooooogle hypermobile hsd calisthenics recovery physicaltherapy
