A tool to focus thumb engagement and thumb pressure strength training. The rounded grip folds nicely into the nooks and crannies of the thumb web while, the fingers stay flat and lightly engaged forcing the thumb to flex inward to keep the weight up.
Bonus: The All Thumbs has a few other functions including a hyper rounder crimp edge to do some warmup lifts with as well as standard style pinch. The swiss army knife of grip tools.
