The Aperto GripForm™ Trainer is your all-in-one solution for building powerful, mat-ready grip strength — no matter where you train. Designed using authentic 450gsm pearl weave gi material and a thick, reinforced lapel edge, this tool brings the feel of jiu-jitsu grips into any strength and conditioning workout.
Whether you're training for gi or no-gi jiu-jitsu, rock climbing, or simply want to level up your grip endurance, the GripForm™ Trainer integrates seamlessly into your routine. Attach it to cable machines, kettlebells, resistance bands, or pull-up bars to simulate real fight scenarios and develop the forearm, finger, and tendon strength needed to dominate the mats.
Lightweight, compact, and built to last, it's perfect for athletes who want jiu-jitsu-specific grip training without being limited to the gym.
Train smarter. Grip stronger. Turn every workout into a grip fight.
