The Complete System

Four Steps.
One Unbreakable Grip.

Most brands sell a product. We built a system around grip health — from baseline assessment to progressive training to measurable gains.

01
Step 01
Assess

Measure your baseline with our free grip strength calculator. See where you rank vs athletes your age — by sport.

  • Free grip strength calculator
  • Age & sport normative data
  • Understand your health risk level
Test Your Grip

The Science

Grip Strength Is
A Longevity Metric

The research is unambiguous. Grip strength predicts cardiovascular health, injury risk, surgical recovery, and all-cause mortality better than most lab tests. And almost no one tracks it.

Grip strength decline per decade after age 30 if untrained
#1
Predictor of surgical recovery outcomes — stronger grip, faster healing
6wk
Average time to measurable strength gains with consistent training
01
The Heart Connection
Studies directly link low grip strength to higher rates of hypertension, stroke, and cardiovascular events. Your hands telegraph your heart health.
02
Performance Cap
In every sport, your grip is the connection point between you and the equipment. A weak grip caps your ceiling — in golf, lifting, tennis, climbing, everything.
03
Trainable at Any Age
Unlike most biomarkers, grip strength responds rapidly to training. 5 minutes of focused work per day produces measurable results within weeks — at any age.

"Went from 88 lbs to 119 lbs in 6 weeks. I'm 54 years old and thought grip strength was just for powerlifters. The dynamometer showed me exactly where I was — and where I got to. This thing works."

"I'm a golf instructor and I recommend this to all my students now. The grip tester alone changed how I coach — students can finally see the number. Grip + the hand tape combo is unreal."
Jason T.
✓ Verified Buyer · Golf
"The hand tape is the only tape that actually stays on through a full lifting session. I've tried everything. The grip-lock is real — doesn't roll, doesn't peel. Ordered 4 packs."
Sara K.
✓ Verified Buyer · Olympic Lifting
"I bought this after my doctor mentioned grip strength at my annual physical. Tested at 71 lbs at 47. Eight weeks later I'm at 103. My wife started using the program too. Best health purchase I've made in years."
David L.
✓ Verified Buyer · Age 47
"As a rock climber I've tried every glove and tape out there. Nothing compares. These stay on when you're sweating, don't bunch up on the crimp, and my hands actually recovered faster between sessions."
