Lucy R. ★★★★★

The reinforced steel spring gives a satisfyingly solid resistance that I can really feel working my forearms. It's tough enough to challenge me but hasn't lost any tension after a month of daily use.

Emma ★★★★★

I've been using this for a few weeks now, and the steel spring really holds up during heavy reps. My forearm endurance has noticeably improved since I started.

Aurora ★★★★★

The reinforced steel spring gives just the right amount of resistance without feeling flimsy, and it’s already helping my deadlift warm-ups feel more solid. Sturdier than the cheap plastic trainers I’ve burned through before, this one should actually last.
