Our Story

Built in a Garage. Proven by Physics.

Two lifters. 20+ years of training. One realization that changed everything.

Something Didn’t Add Up

We weren’t looking for a new exercise. We were trying to get more out of the ones we already knew worked.

So we started experimenting—adjusting angles, using ropes, changing how the weight felt.

Small changes completely changed muscle activation.

It Wasn’t the Weight. It Was the Distance.

The distance between your hand and the cable connection—the moment arm—was driving everything.

More distance meant more torque. More torque meant more tension.

Same movement. Completely different stimulus.

The First Prototype

One day a cable handle frayed. Instead of replacing it, we went to a hardware store and built something ourselves—using plumbing parts and the grip from the broken handle.

It wasn’t pretty. But it worked.

We Felt It Immediately

Better targeting. Stronger contractions. More control through every rep.

Movements we’d done for years suddenly felt completely different.

Then We Tested It

We didn’t want to rely on feel alone. So we used EMG testing to measure muscle activation.

Up to 30% Greater Muscle Activation

Compared to a traditional handle.

Built for Real Training

  • Cast stainless steel construction
  • Textured rubberized grip
  • Dual rotation system

Why SupiGrip

The design allows you to naturally supinate your grip—changing angles, increasing torque, and targeting muscles more effectively.

The name just stuck.

Who It’s For

  • Lifters who want better muscle activation
  • Those focused on proper mechanics
  • Anyone chasing hypertrophy with smarter resistance
  • Lifters who want to reduce joint stress
  • Those looking to protect their joints from overloading

A Better Way to Train

This didn’t start as a business. It started as two guys in a garage trying to train better.

SupiGrip is the result.

Better mechanics. Better activation. Smarter training.
