Best thing ever!
I sit in a office all day & workout 3 days a week so my back & neck get stiff a lot . Lay flat on your back or lean against a wall & roll the ball around it will get rid of those hard to reach spots it feels amazing . They are a bit rough but that’s how lacross balls are I would highly recommend one to someone who struggles with a stiff back you can Google youtube videos on how to use one
