The Best Grip Strengtheners

Disclosure:Grip & Gait earns a commission when you buy through links on this page, at no extra cost to you. It never changes what we recommend or the order we rank things in — here is exactly how we’re funded.

The short version

If you want one thing, buy the Hiyoga adjustable gripper. It loads the crush grip, the resistance moves as you get stronger, and the rep counter is the difference between a habit and a drawer ornament. If your hands hurt rather than feel weak, buy the CanDo Theraputty instead — it is the budget pick here, it costs less than a coffee, and graded putty is the medium the best-evidenced hand exercise program in the literature was built around. If you are doing this because of something you read about grip strength and longevity, add the Handeful grip tester, because a number you can retest in eight weeks is the only way to tell training from enthusiasm. And whatever you buy, the FitBeast extension set is the one most people are missing: every other item on this page trains the hand closing.

A hand does three jobs, and a gripper trains one

This is the whole reason a grip-strengthener page needs to exist rather than a single product link. “Grip” is not one movement. It is at least four, they fail independently, and the thing almost everyone buys trains exactly one of them.

Only two of those five rows describe a product you squeeze. That mismatch is why a cheap gripper disappoints so many people: they bought a crush-grip tool for a support-grip or extension problem, and then concluded grip training does not work.

What the grip-strength research actually says

Grip strength is genuinely one of the better-known markers in epidemiology, and the honest version of the finding is narrower than the headlines. The PURE study in The Lancet measured grip strength across a very large international cohort and found it predicted mortality and cardiovascular outcomes. What the authors did not show — and said so — is that improving your grip changes those outcomes. Measurement is the validated part. Squeezing a spring is a plausible inference stacked on top of it.

Where there is dose-response evidence, it is about resistance training rather than hand gadgets. The Bayesian network meta-analysis of resistance-training dose in older adults with sarcopenia looked at what actually moves handgrip strength, and what it studied was programmed resistance exercise, not grippers. So if the goal is the health marker, a gripper is a supplement to lifting and carrying things, not a substitute for it. If the goal is a hand that can hold a bar, a gripper is on the nose.

For sore hands the evidence is better and it points somewhere specific. The SARAH randomized controlled trial in The Lancet tested a tailored, progressive hand exercise program for rheumatoid hands against usual care and found improved hand function that persisted at twelve months. The program is the intervention. Putty is the cheapest way to own the medium it runs on, which is exactly why a tub of putty ranks above a more expensive device on this page for that reader.

How we ranked these

1. Which of the grip jobs it trains — and whether the listing is honest about that. A gripper that implies it trains “grip” wholesale loses points.
2. Somewhere to progress to. A single fixed resistance is either impossible today or useless in six weeks. Adjustable resistance or graded sets, every time.
3. Whether a painful hand can start. The lowest grade matters more than the highest. An X-soft putty or the lightest band is the entry point; a maximal spring is not.
4. Whether it survives contact with real life. Desk-sized, no charging, no app. The failure mode in this category is not breakage, it is being put in a drawer.
5. We rank down advertised resistance numbers. Consumer grippers print ranges with no documented test method anywhere on the listing. We quote no resistance spec for any item here, because none of these makers publishes one we could check. Treat the settings as relative to each other and nothing else.

Which one for which person, in one line each

• You lift, and your grip gives out before the muscle does: the Hiyoga adjustable gripper, plus heavy carries. The gripper trains the squeeze; the carries train the part a gripper cannot reach.
• You climb, or you type all day and your fingers will not straighten: the FitBeast extension set. This is an extensor and pinch problem, and no amount of squeezing fixes a hand that is already too good at closing.
• Your hands are stiff and sore in the morning: the CanDo Theraputty at X-soft, warmth first, and a program rather than a product. Start below what feels challenging.
• You read about grip strength and health and want to act on it: the Handeful grip tester first, so you have a baseline, then resistance training. Retest the same hand, same posture, same time of day, in eight weeks.
• Skip the compression gloves as a strengthener. They are not one. Some people like them for overnight comfort, which is a legitimate reason to own something — but the A-GLOVES randomized trial found no clinically important difference against placebo gloves, and more adverse events in the arthritis-glove arm.

A starting program that is not made up

We are not going to invent a protocol. What we can do is state the shape the evidence supports and keep the dosage conservative. For a healthy hand: three sessions a week, two to three sets of eight to twelve closes at a resistance you can finish with control, plus one heavy carry for distance on a training day, plus one set of extension work for every two sets of closing. Progress the resistance only when the last rep of the last set is still clean.

For a painful or arthritic hand, the program is the prescription and it should come from a hand therapist — SARAH worked because it was tailored and progressed by a clinician, not because putty is magic. Start at the easiest grade, stop short of pain rather than working into it, and expect weeks rather than days. Heat before the session helps enough that the Cochrane review of thermotherapy for rheumatoid arthritis treats it as a reasonable adjunct, while being clear it does not change the disease.

Where a grip strengthener is the wrong purchase

If the problem is pain rather than weakness, the page you want is hand and grip strength, which routes by symptom instead of by product. Wrist pain on the thumb side or with gripping is wrist and forearm. Pain at the outside of the elbow when you grip is tennis elbow, and it is treated at the forearm, not the hand. Arthritic hands in general are covered on arthritis. And if your fingers are the limiting factor on a wall rather than at a desk, recovery tools for climbers has the climbing-specific version of this argument.
