Your lungs are fine. Your back is fine. Your hands are the problem.
Chest-to-bar is where grip gear gets exposed fast. One slipping hand and your timing breaks, your kip shortens, and the rest of the set falls apart rep by rep. It is not dramatic — it is just physics. Bad contact with the bar costs you reps whether you notice it or not.
The fix is simpler than most people make it. Get grips built for gymnastics volume, not general training. At RBST Gear Co., that means two options — and picking the right one takes about 30 seconds.
The Iron X
For athletes who compete
Made from natural rubber and Kevlar — yes, the bulletproof vest material — the Iron X is built for athletes who cycle chest-to-bar in rounds of 15, show up to competitions, and need a grip that does not quit when the workout gets ugly.
The carbon fiber texture surface locks you in without being slow on transitions. The Wrist-Flex Strap stays put when your heart rate hits 180. The Precision Cut fit means no bunching, no folding, no mid-kip surprises.
One of our athletes had his grips rip in a finals event. We replaced them at our booth on the spot, then shipped him Iron X grips the next day. That is the standard we hold ourselves to.
Rated 4.9 stars. 74 reviews. No slip, no rips, no excuses.
THE IRON CLAW
for athletes who train hard every day
The Iron Claw is premium silicone — comfortable, grippy, and forgiving enough for athletes still building their gymnastics skills. Same Wrist-Flex Strap system. Same protection. A softer feel that works across different bars and environments without drama.
277 five-star reviews. Athletes say the same thing over and over: no slipping, no tearing, holds up through everything.
If you are not competing yet but you are showing up consistently and want hands that survive the week, this is your grip.
