I use a slam ball but a soccer ball or volleyball that is adequately inflated would probably work too. If you are tough and flexible you can use a softball or something much firmer but it will hurt a lot more if you are not ready for it.
I regularly roll out my ass and upper back with a lacrosse ball or softball, but haven't tried it on my psoas yet.
What a coincidence. I was searching YouTube for exercise for back pain. I actually have pain in my left side of body. Some pain is in back and some in leg.
And this dude's (jujitsu master) exercise was the only thing to help with my pain
Here is a video using a much smaller ball: https://www.youtube.com/watch?v=OQuQ_aKlDjI
Here is another one: https://www.youtube.com/watch?v=_F-0rtFbOgI @ 1:15 is about the position that I use. Lying down, one leg out to the side and one leg straight back.
