Every set begins and ends in the J-cup. Nike Strength Pro J-Cups are rated to 1,100 lb per pair with the rack, so athletes rack and unrack at the top of their range without thinking about it. The frame steps up to 8mm steel from the 6mm on the core cup, and the cup itself moves from nylon to UHMW for better wear resistance under repeated loading. The cup shape carries over unchanged — sized to make racking and un-racking as smooth as possible, with room to find the hooks again on a heavy bench or squat. A nylon pad on the rack-facing side protects the upright’s powder coat as the cups are moved between heights.
JUST DO IT.
