On a roller, at a stiff or sore spot, contract the muscle, breathe, then slowly relax, and repeat two or three times to desensitize it and improve range of motion.

if I find something that's uncomfortable or stiff or doesn't feel like my other side I'm going to stop found a place to work I'm going to build take a big inhale so I take a 4 second inhale I want to teach myself that I need to be able to breathe in this position my one of my you know friends Greg Cook is like if you can't breathe in position you don't own a position you know that sounds very iang guard too but what we're going to do is we're going to say it's okay to breathe here and I'm going to contract here and then I'm going to slowly relax and soften that's Tempo that's moving slowly and I can handle higher loads and what'll end up happening is if I repeat that cycle two or three times guess what my brain desensitizes that changes range of motion
