I had a chronically tight calf muscle on one leg and while visiting a running store for some gels, tried a theragun on the calf. I walked out of there after using it and thought wow this feels pretty great.
Couldn’t justify the price of the actual theragun on a whim so I bought this:

Few minutes here and there with it has really made quite a difference. And it feels good on quads and glutes too.
