Ruby S. ★★★★★

The reinforced steel spring hasn’t budged a millimeter after months of daily squeezing, and my forearms finally look like I actually lift. It’s the first trainer that’s made me feel the burn in my fingers, not just my palm.

William W. ★★★★★

I’ve been using this for a few weeks now and the steel spring really does provide consistent resistance through the full range of motion. My forearms feel noticeably stronger after just a few sessions.

Madison X. ★★★★★

The reinforced steel spring gives a satisfyingly solid resistance that I can really feel working my forearms after just a few sets. It's tough enough to challenge me without feeling like it's going to snap, which is exactly what I needed for my training routine.
