I didn't know just how many knots and adhesions I had in my calves and IT band until I gave them a once-over with my TheraGun. Use it after every hard exercise session, and I love it.
This massage tool gets the job done! The accompanying app is also a great feature. I use the tool daily for upper back/neck tension release. I haven't tried it before/after a workout just yet, but I'm not concerned about it performing well.
