★★★★★4.7• 2,106 reviews
Grip is the strength you use all day. This is how you build it.
- Adjustable coil-spring resistance — one trainer from warm-up to max squeeze
- Digital counter on the handle tracks reps; tap to reset between sets
- Ergonomic rubberized handle that doesn’t dig in at high resistance
- Pocket-sized — desk, car, couch, gym bag. Train while you’d otherwise scroll
“My grip was the first thing to give out on every deadlift and every climb. Three sets a day at my desk, cranking the knob up every couple of weeks — two months later my hands aren’t the weak link anymore.”

Build a grip that doesn’t quit.
Dial-in resistance, a digital rep counter and a handle built for max squeezes — train your hands like you train everything else.
Set the load. Count the reps.
DialLoad™ adjustable resistance
A knurled knob at the end of the spring sets the squeeze. Turn it up as you get stronger — one trainer, every level.
RepCount™ digital counter
An LCD on the handle logs every full squeeze and resets with a tap, so a set is a number, not a guess.
ErgoCore™ handle
A ribbed, rubberized grip shaped to the palm. No hot spots, no slipping, even at the top of the dial.
PowerCoil™ spring
A heavy coil spring in a reinforced housing — smooth, even resistance through the whole squeeze, rep after rep.
Pocket-sized
Desk drawer, glovebox, gym bag, couch. Three sets fit anywhere you’d otherwise be scrolling.
Three sets. Anywhere.
On a call, in traffic, between episodes. Squeeze to the top, hold, release — the counter keeps score, the knob keeps it hard.
Why grip is the weak link
Your hands give out before the rest of you does.
Deadlifts you drop before your back is tired. Pull-ups that end when your fingers open, not when your lats do. A climb that ends at the pump. Grip is the strength you use in every lift, every hang and every jar lid — and it’s the one almost nobody trains on purpose.
- Forearms and hands lag behind everything else you train
- Dollar-store grippers are one fixed resistance — too easy in a week
DialLoad™ adjustable resistance
Turn the knob. Keep progressing.
Fixed grippers stop working the week you outgrow them. The knob at the end of the spring housing dials the resistance up or down, so you warm up light, work heavy, and add load every couple of weeks — the same progressive overload you’d use on any lift.
- Light for warm-ups and high-rep endurance sets
- Crank it up for low-rep max-strength squeezes
RepCount™ digital counter
Every rep, counted. Every set, a number.
The LCD on the handle ticks up with each full squeeze and resets with one tap. Set a target, hit it, log it — you stop losing count mid-set and start tracking real progress week over week.
- Counts complete squeezes, so half-reps don’t pad the number
- One-tap reset between sets
ErgoCore™ handle
Comfortable at the top of the dial.
Cheap grippers bite into your palm the moment the resistance gets serious. This handle is ribbed, rubberized and shaped to the hand, so the force goes into your fingers and forearm — not into a pressure point.
- No slipping when your hands sweat
- Fits a wide range of hand sizes
Train anywhere
The workout that fits inside dead time.
Hands and forearms recover fast, so they can take work every day. Three sets at your desk, a set at every red light, a few squeezes during the game — it adds up to real forearm strength without ever adding a gym session.
- Desk, car, couch, carry-on
- Minutes a day, every day
Built to be squeezed
Thousands of reps. Same resistance.
The coil spring sits in a reinforced housing, the pivot is solid, and the handle is rubber over a rigid core — nothing that flexes, creaks or loosens. Max squeezes every day for months, and the top of the dial still fights back exactly like it did on day one.
- Heavy coil spring, not a thin wire
- Rigid frame — no wobble at full load
Every part earns its place.
Coil spring
Heavy-gauge coil in a reinforced window. Smooth, even resistance through the whole squeeze.
Digital counter
Reads at a glance mid-set. Tap to reset, start the next one.
Ribbed rubber grip
Textured rubber over a rigid core. Stays put when your hands sweat, never digs in.
Bag-sized
Fits the side pocket of a gym bag or the glovebox. Grip work travels with you.
One hand. Every setting.
Adjustable on the fly
Light, medium, heavy — one knob, one trainer

My hands aren’t the weak link anymore
Grip was the first thing to give out on every deadlift and every climb. Three sets a day at my desk, cranking the knob up every couple of weeks — two months later my hands aren’t what fails first.

The counter actually counts
Assumed the digital counter was a gimmick. It only ticks on a full squeeze, so you can’t cheat it with half reps, and the reset is one tap. I do 3 x 25 now instead of “a bunch.”

Six months of max squeezes, still fights back
I’ve snapped two cheap wire grippers. This one has a real coil spring in a solid frame — no creak, no wobble, and the heavy setting is still heavy after six months of daily sets.

Fits my hand — start on the light end
Most grippers are sized for huge hands; this one I can actually close. Even the lightest setting was a real workout for me the first week, so don’t crank it on day one. Four stars because I’d love a wrist strap.

Barre chords stopped hurting
I practice two hours a night and my fretting hand used to cramp halfway through. A few weeks of sets on this and I get through the whole session. Keep it next to the amp.

Pulled without straps for the first time
Double-overhand, no straps, a weight I used to need straps for. That’s the whole review. Sets on this every night while I watch TV did that.

Good trainer, know it’s not tiny
Forearm strength is noticeably better on the back nine. It’s a bit chunkier than the wire grippers because of the counter and the spring housing — fits a bag, not a jeans pocket. Worth it for the adjustability.

Bought one, ended up with two
Got it for my husband, kept stealing it during calls, bought my own. Mine lives in the desk drawer on a lighter setting, his is cranked up in the gym bag. Same trainer, two very different workouts.

A day, anywhere, is all it takes to make grip stop being the weak link.
Worried it’ll be too easy — or too hard?
It’s adjustable. Try it for 30 days; if it doesn’t fit your hands or your strength, send it back.

Straight answers
Will the spring snap or wear out?
It’s a heavy coil spring in a reinforced housing, not the thin wire you find on bargain grippers. Coils like this are built for thousands of compressions. Keep it dry and it will keep fighting back.
Is the top setting actually hard?
Yes. The light end is a warm-up; the heavy end is a low-rep max-strength squeeze that most people can’t close cleanly on day one. The point of the dial is that you grow into it over months.
Does the counter really count?
It ticks once per full squeeze — a half rep doesn’t register — and resets with a tap. It’s there so a set is a number you can beat next week, not a guess.
Will it hurt my palm at high resistance?
The handle is ribbed rubber over a rigid core and shaped to the hand, so the force goes into your fingers and forearm instead of a pressure point. If it bites, you’re holding it too far forward — seat it in your palm.
Why not a $5 wire gripper?
A wire gripper is one fixed resistance: too hard the first week, too easy by the fourth, and no way to track reps. This one adjusts as you progress and counts every rep, which is the difference between squeezing something and training.
Training with it
How do I start?
Set the knob to the light end, squeeze until the handle closes, hold a second, release slowly. Three sets of 10–15 per hand. When 15 feels easy, turn the knob up.
How often can I train grip?
Hands and forearms recover quickly, so most people train daily or near-daily. If your forearms are sore, take a day — soreness is the signal, not the schedule.
Will it help my deadlift / pull-ups / climbing?
Grip and forearm strength are the limiting factor in all three for a lot of people. Train it directly and it stops being the first thing to fail. It won’t replace the lift itself — it removes the bottleneck.
Does it work for both hands?
Yes — the handle is symmetrical, so swap hands and train both evenly. Do the same sets left and right.
Fit & safety
Will it fit small or large hands?
The handle is sized for a wide range of hands. Smaller hands should start on the light end — closing the handle fully is the goal before adding resistance.
Can I use it after an injury or surgery?
This is a fitness tool, not a medical device. If you’re recovering from a hand, wrist or elbow injury, ask your doctor or physio first and follow their program, not ours.
Is it safe around kids?
Keep it away from small children. The spring and pivot can pinch fingers, and it’s not a toy.

What’s the return policy?
