ADJUSTABLE GRIP TRAINING · REP COUNTER
Every rep
counted.
Most grippers leave you guessing. Turn the dial to set your resistance, seat your fingers in the contoured handles, and the mechanical counter clicks up with every full squeeze — so you know exactly where the set ended and where the next one starts.

What It Does
What It Does
The CoreForm Grip Trainer is an adjustable hand gripper with a built-in mechanical rep counter.
- Trains crush grip — the strength that keeps a barbell, a pull-up bar or a climbing hold in your hand.
- Adjustable resistance — a threaded dial on the spring lets you start light and tighten as you get stronger, so one tool covers your first week and your fiftieth.
- Counts every rep — the counter at the base clicks up with each full squeeze, so you always know whether a set was 20 reps or 50. No batteries, no app.
- Resets in a turn — twist the knob at the bottom to zero the counter between sets or hands.
- Built to be squeezed thousands of times — steel coil spring, black frame, contoured TPR handles with finger grooves that stay put when your hands are sweaty.
Who it's for: lifters who lose the bar before they lose the lift, climbers, grapplers, racket-sport players, and desk workers or musicians who want hands that don't fatigue.
General fitness equipment, not a medical device. The counter counts repetitions; it does not measure force.
How To Use
How To Use
- Set the dial. Turn it to a resistance you can squeeze fully for 10–15 reps with clean form. Start lighter than you think.
- Seat your fingers in the grooves and close the handles until they touch. Each full close counts one rep on the counter.
- Do 2–4 sets per hand, 2–4 times a week, with a rest day between harder sessions.
- Progress. When 15 clean reps feel easy, tighten the dial a quarter turn.
- Reset. Twist the reset knob to zero the counter before your next set.
A full 4-week plan, four core sets and sport-specific add-ons are in The Grip Count Method e-book, free with every order.
Stop if you feel sharp pain in the fingers, wrist or forearm. Consult a physician before beginning any exercise program.

MOST PEOPLE NEVER TRAIN IT DIRECTLY
Give your grip its own workout.
Your grip only gets trained as a side effect of everything else — and it fails first. Give it ten minutes of its own: between sets, at your desk, on the couch. Set the dial, squeeze until the handles touch, read the count. Stronger hands show up in every lift, every carry, every handshake.
Rest 90 seconds? That’s a set for your hands.
No rack, no setup. It lives in a drawer.
Tighten the dial when 15 clean reps feel easy.
COMPARE THE DIFFERENCE

Adjust your resistance. Count your reps. Keep every set on track.

MATERIALS & DESIGN
Built around your grip.
Every part is there for a reason: handles shaped for fingers, a spring that takes thousands of closes, a frame that keeps everything in line.
Contoured TPR handles
Soft-touch rubber with finger grooves. Stays put when your hands are chalked or sweaty, no hot spots on long sets.
Steel coil spring
One heavy-gauge coil, threaded dial on top. Built to be squeezed thousands of times without going soft.
Two-handle frame
Pistol-grip shape with a pivot at the base. The handles travel in a straight line, so every rep feels the same.
ON THE GO · GYM · HOME

GOT QUESTIONS?
FREQUENTLY ASKED QUESTIONS.
1 Does the counter measure how hard I squeeze?
No. The counter counts repetitions — it clicks up once every time the handles close fully. It does not measure force. Resistance is set separately with the dial on the spring.
2 How do I adjust the resistance?
Turn the threaded dial on top of the spring. Clockwise compresses the spring and makes the squeeze harder; counter-clockwise makes it easier. Start where you can do 10–15 clean reps and tighten a quarter turn when 15 feels easy.
3 How do I reset the counter?
Twist the knob at the base of the handle until the window shows 00. Do it between sets, or when you switch hands.
4 Does a half squeeze count as a rep?
No. Only a full close registers, so the number you see is the number of complete reps you actually did.
5 How big is it, and does it need batteries?
About 16.5 × 13 cm (6.5 × 5.1 in) — it fits a desk drawer or the side pocket of a gym bag. The counter is mechanical: no batteries, no app, nothing to charge.
6 Who is it for?
Lifters who lose the bar before they lose the lift, climbers, grapplers, racket-sport players, and desk workers or musicians who want hands that don’t fatigue. Start light if you’re new to grip training.
