Gummimassageball

The firmness is just right for digging into tight glutes, and the size lets me target my lower back against a wall without it slipping. I've used it every evening this week and the release in my hips is noticeably quicker than with a foam roller.

I keep this medium-firm ball by my desk and roll my feet on it after long days standing up. The size is just right for getting into my arches without slipping around, and the pressure feels deep without being brutal.

Rolled this under my shoulder blade after a long week of desk work and the medium-firm density really digs in without feeling brutal. Took a day or two to figure out the right amount of body weight to lean in, but once I did my knots actually let go.
