They do the “trick”...
I’ve been using tennis balls to loosen up my back and my glutes in the morning before I arrive. I am recovering from several injuries. However, I think that these are much better for that purpose, as they’re soft enough, however much harder overall. My only wish, which is a bizarre thing, but I wish everything didn’t come in bright colors. Many of us like more muted tones or natural tones. Just a suggestion…
