Grip Strength
154 lbs

Your grip gives out before your back does. Fix that.

Deadlifts, pull-ups, combat sports — grip is the first thing to fail. Dial the resistance from 44 to 154 lbs, count every rep on the built-in digital counter, and progress it like any other lift.

Spring Reinforced high-tension steel, built for years of daily work
Handle Ergonomic anti-slip grip — secure under max effort

The Founder

Meet Gary Steele.

Former professional wrestler. Former NWA World Heavyweight Champion. Qualified personal trainer with 35 years under the iron. Gary has trained — and been trained — at the highest level, and N.T.R.L. is everything he wishes he'd had in his locker room.

He watched the fitness industry drift — cheap springs, flimsy plastic, gimmicks built for the algorithm. So every N.T.R.L. tool is built the way he trains: honest, durable, and engineered for people who actually show up.
