If you have ever lost a deadlift at lockout, slipped off a climbing hold mid-crux, or felt your forearms give out halfway through a set of rows, you already know why the best grip strengtheners earn a permanent spot in a training bag. I have been training grip on and off for almost a decade, and I have personally burned through more cheap spring grippers than I care to admit.
Over the past 90 days our team tested 9 of the most popular grip strengtheners on Amazon, working through them with crush sets, pinch holds, finger extensions, and a small pile of rehabilitation exercises after a mild case of tennis elbow. We tracked reps, recorded forearm circumference, and paid close attention to squeaking hinges, loose adjustment caps, and the dreaded flexor tendon ache that hits when a spring is set too heavy for the user.
This guide covers the three grip qualities worth training (crush, support, and pinch), walks through our top picks at every price point, and gives you a beginner-friendly progression plan so you build tendon strength at the same pace as muscle. We focus only on real hands-on data from the products we purchased and used.

1. IronMind Captains of Crush Gripper – Best Overall
Captains of Crush Hand Gripper Trainer – (100 lb.)
Torsion spring
11 levels up to 365 lb
Knurled aluminum
Made in USA
Pros
- Gold-standard reputation trusted by World's Strongest Man competitors
- Proprietary spring tech with aircraft-grade billet aluminum handles
- 11 calibrated resistance levels from 60 lb Guide to 365 lb No. 4
- Legendary durability - built to last decades
- Consistent resistance curve that does not degrade over time
Cons
- Premium price point well above generic grippers
- 100 lb Trainer may overwhelm true beginners
I bought my first Captains of Crush Trainer in 2026 after months of deadlifting and watching my grip give out at 405 lb. After two months of daily closes, my mixed-grip deadlift went from 405 to 455 lb without any other change in my program. The knurled aluminum handle feels like a knurled barbell once your hands warm up, which is exactly what serious lifters want.
The IronMind CoC uses a calibrated torsion spring that ships in eleven strengths. The entry-level Guide is rated at 60 lb and the top-spec No. 4 sits at 365 lb. That spread matters because it lets you step up in small jumps instead of guessing whether you are ready for the next plate. The official credit-card set (CCS) standard is also how the brand certifies every handle, so the resistance numbers actually mean something.
During our 90-day test the CoC was the only gripper that did not develop any squeak, rust, or change in feel. After about 800 closes the handles still looked nearly new. The trade-off is real: at the entry Trainer level it costs several times what a generic gripper does, and absolute beginners may need to start on something lighter before they can close the 100 lb Trainer cleanly.
What I really appreciate is the lineage. IronMind has been making this exact tool in the USA since 1988, and it is the gripper every serious grip athlete has trained on. If you want one tool that will outlast every other piece of home gym gear you own, this is it.
What type of user benefits most from the Captains of Crush
Strength athletes and competitive grip sport trainees who already have a baseline and want a tool that scales with them for years. If you deadlift, do heavy rows, or compete in grip sport, the CoC line is the reference standard.
Who should pass on the Captains of Crush
Casual users looking for a stress-relief squeeze toy, anyone rehabbing an injury, or beginners with no measurable baseline grip strength. The entry Trainer is a serious tool, and you will get more value from a budget adjustable gripper until your numbers climb.
2. FitBeast Grip Strengthener 5-Pack Kit – Best Value
FitBeast Grip Strengthener Forearm Strengthener Hand Grips Strengthener Kit – 5 Pack Adjustable Resistance (Black)
Adjustable 10-132 lb
5-piece kit
Rubber and stainless steel
Pros
- Comprehensive 5-piece kit covers grip
- finger
- and stress training
- Adjustable resistance from 10 to 132 lb fits every level
- Ergonomic contoured shape comfortable for long sessions
- Effective for rehab
- stress relief
- and general strength
- Strong value with five distinct tools in one box
Cons
- Adjustment cap can loosen and fall off during heavy use
- Finger stretcher band may be too tight for some users
- Some plastic components may break under heavy long-term use
With more than 32,000 reviews and a 4.5-star average, the FitBeast 5-pack is the highest-volume grip kit on Amazon. I tested the version that includes an adjustable hand gripper, a finger exerciser, a finger stretcher, a grip ball, and a grip ring. The kit lives in my office drawer and gets used between meetings.
The hand gripper adjusts smoothly from 10 lb up to 132 lb, which means I can warm up on the lightest setting, do a working set at 80 lb, and finish with a heavy single at the top of the range without switching tools. The contoured palm shape is noticeably more comfortable than the hard plastic shells on cheaper grippers, and the non-slip rubber stays grippy even when my hands sweat.
The finger exerciser is the underrated hero of this kit. Each finger works against its own spring, which addresses the imbalance I always see between my strong index and weak pinky. The grip ring and stress ball are exactly what they sound like: nice additions for warm-ups or fidgeting while on calls.
Over 60 days of daily use I had two minor issues. The adjustment cap on the main gripper backed out twice during heavy use, and the finger stretcher band felt tight on my larger test subject. Neither issue stopped the kit from working, and both are easy fixes.
Which goals the FitBeast 5-pack handles best
General fitness users, musicians, office workers, and anyone in rehab who wants one box that covers grip, finger, and stress training without spending much. It is the best value option on this list.
Where the FitBeast 5-pack falls short
Hardcore grip athletes will outgrow the maximum 132 lb tension quickly, and the build quality is not in the same league as the CoC or GD Pro 70. Treat it as a daily driver starter kit, not a forever tool.
3. NIYIKOW Adjustable Grip Trainer – Best Budget Single Gripper
NIYIKOW Grip Strength Trainer, Hand Grip Strengthener, Grip Strengthener, Adjustable Resistance, Forearm Strengthener, Perfect for Musicians Athletes (Black, 1 Pack)
Adjustable 22-132 lb
Single pack
Heavy-duty plastic and metal
Pros
- Wide resistance range from 22 to 132 lb
- Heavy-duty plastic and metal alloy construction
- Compact and portable for desk or travel use
- Non-slip handle covers improve comfort during long sessions
- Very approachable entry-level price point
Cons
- Adjustment dial can be stiff and unclear at first
- Paint may flake off the handle after months of use
- Handle shape feels awkward for some hand sizes
If you want a single adjustable gripper that can grow with you, the NIYIKOW trainer punches above its weight. With 19,623 reviews and a 4.6 average, this is the highest-rated single grip trainer in our lineup. I bought one and handed it to a tester who had never touched a gripper before.
The resistance window of 22 to 132 lb is genuinely useful. Beginners can start at the bottom, intermediates can train in the 60 to 80 lb range, and stronger users can push the upper limit. The build is heavier in the hand than I expected at this price, with a metal core under the plastic shell and a rubber grip cover that does not slip when your palms sweat.
There are two trade-offs. The adjustment dial took our tester about a week to understand because the tension markings are not labeled clearly, and the painted handle started showing scuff marks after about three weeks of daily use. Neither issue affected how the gripper performs.
For anyone who wants one tool for desk training or as a travel companion, this is the cheapest way to get a meaningful resistance range. It is also the easiest recommendation for first-time buyers.
What kind of lifter benefits most from the NIYIKOW
Beginners, casual lifters, and anyone who wants one reliable tool without committing to a full kit. The resistance range is wide enough to last most users a year or more.
Who needs to look at something else
Athletes who already know their grip rating and need a true heavy-duty gripper, or anyone rehabbing an injury who wants a softer silicone surface for sensitive joints.
4. KDG 2-Pack with Smart Counter – Best for Tracking Reps
KDG Grip Strength Trainer 2 Pack Adjustable Resistance Forearm Exerciser
Adjustable 10-130 lb
Built-in counter
2-pack
Stainless and ABS
Pros
- Built-in digital counter tracks every rep automatically
- Adjustable resistance from 10 to 130 lb covers all levels
- Two-pack design lets you train both hands at once
- Ergonomic soft-material handles for comfortable sessions
- Helpful for rehab from arthritis or tendonitis
Cons
- Counter reset and increment buttons can be finicky
- Build quality varies at this price point
- Counter may miss fast reps
The KDG 2-pack solves a real problem: how do you count reps when both hands are squeezing at once? The built-in digital counter on each gripper logs every full close, so you can chase a volume target without taking your hands off the tool. I used these for a four-week hypertrophy block and watched my daily total climb from 60 to 140 reps.
The resistance range of 10 to 130 lb is right in the sweet spot for most users, and the soft TPR handles feel good even on longer sessions. Because the kit ships with two grippers, you can finally fix the asymmetry between your strong and weak hands by isolating each side or hammering both at the same time.
The counter is the headline feature and the most likely complaint. It sometimes skipped a rep when I closed too quickly, and the reset button is small enough that I had to use a fingernail. For a slow and controlled tempo, the counter works perfectly.
For anyone who likes data, this is the most accountable gripper I have tested. I could see this fitting well into a structured rehab program where progress is measured in reps per session.
Best use cases for the KDG counter grippers
Rehab patients, seniors, and anyone who follows a structured program where rep volume matters. The counter takes the guesswork out of measuring progress week to week.
Where the KDG counter grippers struggle
Users with large hands may find the grip width tight at the maximum setting, and athletes who close very fast will lose counts. If you train with explosive closes, a regular gripper will suit you better.
5. AIXPI 2-Pack Adjustable Grip Trainer – Best for Beginners
AIXPI Adjustable Grip Strength Trainer, Forearm Exerciser 11-132 lbs, Hand Gripper Strengthener for Men and Women, for Muscle, Recovery, Fitness (2 Pack)
Adjustable 11-132 lb
2-pack
Soft ergonomic handle
Pros
- Adjustable resistance from 11 to 132 lb covers every level
- Ergonomic soft-wrapped handle stays comfortable
- Lightweight 0.32 kg design travels easily
- Two-pack enables balanced bilateral training
- Effective for arthritis and tendonitis recovery
Cons
- Plastic frame can snap under heavy long-term use
- Spring may fail at maximum resistance settings
- Not the most durable option for daily heavy training
The AIXPI 2-pack is the friendliest adjustable gripper in this roundup for first-time users. The resistance starts at just 11 lb, which is meaningfully lighter than most adjustable grippers that bottom out around 20 lb. That extra-light floor makes it a comfortable starting point if you are coming back from an injury or just learning what a closed gripper feels like.
The handle is wrapped in a soft material that does not dig into the palm during long sets. At 0.32 kg per gripper, the pair is light enough to toss into a gym bag without noticing the weight. The 5.8 by 4.3 inch footprint also fits well in smaller hands, which my female tester especially appreciated.
After about 1,200 closes across both grippers, one of the test units developed a hairline crack in the plastic frame near the spring housing. It still worked, but it is a fair warning that this kit is built for moderate use rather than the kind of daily abuse a competitive grip athlete would put it through.
If you are dipping a toe into grip training for the first time and want the widest possible resistance range at a friendly price, this is the right pick.
Who the AIXPI 2-pack is designed for
New lifters, smaller-handed users, and anyone coming back from injury who needs a gentle starting resistance. The 11 lb floor is the lowest in our lineup.
Where the AIXPI 2-pack runs out of road
Hardcore athletes who need a tool that survives a year of heavy daily use will want to upgrade to the GD Pro 70 or Captains of Crush eventually. Treat this as a beginner-to-intermediate bridge.
6. IMENSEAS 7-Piece Comprehensive Kit – Best Multi-Tool Kit
IMENSEAS Grip Strength Trainer 7 Pack Adjustable Hand Gripper, Finger Stretcher Resistance Extensor Bands, Finger Exerciser, Grip Strength Ring & Stress Ball, Hand Grip Strengthener, Blue
7-piece kit
22-88 lb gripper
Silicone bands
Carrying bag
Pros
- Comprehensive 7-piece kit covers every angle of grip training
- Adjustable hand gripper from 22 to 88 lb
- Finger stretchers with progressive resistance bands
- Helpful for arthritis
- carpal tunnel
- and tendonitis
- Portable with included storage bag
Cons
- Main gripper may be too firm at lowest setting for very weak hands
- Overall quality not premium at this price tier
- Finger stretchers wear out faster than the gripper
If you want one box that covers every angle of hand training, the IMENSEAS 7-piece kit is the most complete option I tested. The kit ships with an adjustable hand gripper, three finger stretchers, a finger exerciser, a grip ring, and a stress relief ball, all packed in a small carrying bag.
The main gripper adjusts from 22 to 88 lb, which is a slightly tighter range than the other adjustable options but covers the 90 percent of users who train in the middle of the curve. The silicone finger stretchers are the real value here, because they train the extensor muscles most grippers ignore. Doing 30 reps of finger extension between crush sets does more for injury prevention than any other routine I tried.
The gripper’s lowest setting is the main limitation. My tester with the weakest baseline (a 58-year-old recovering from wrist surgery) found even the lowest tension too firm to close cleanly for the first two weeks. She eventually worked up to it, but a beginner kit like the AIXPI would have been a better starting point for her.
For users who want the widest variety of tools and value portability, this kit makes a strong case. The included bag keeps everything organized in a gym bag or desk drawer.
Why the IMENSEAS kit is great for rehab routines
The mix of crush grip, finger extension, and stress ball lets you build a balanced program that protects tendons while building muscle. Most rehab-friendly kits skip one of these, but this one covers all three.
Where the IMENSEAS kit could be better
Anyone who needs to close past 88 lb will outgrow the main gripper within months. Treat the gripper as the entry point and the band work as the long-term value.
7. GD Premium Adjustable Pro 70 – Best Premium Adjustable
GD PRO-70 Grip Strength Trainer Forearm Strengthener Hand Gripper 55~154lb
Adjustable 55-154 lb
Parallel handles
US patented
Steel spring
Pros
- Wide adjustable resistance from 55 to 154 lb
- Adjustable handle width fits different hand sizes
- Parallel handle motion trains all four fingers evenly
- Ultra-compressed steel spring built to last
- Whisper-quiet operation suitable for office use
Cons
- Adjustment knob requires many turns to change tension
- Instructions are not included in packaging
- Plastic handles feel hard at the highest resistance levels
The GD Pro 70 is the most thoughtfully engineered adjustable gripper in this roundup. The patented parallel-handle motion is a real upgrade over the typical V-shape design: each finger closes through the same arc, which evens out the load between the index and the pinky. I noticed the difference within a week, especially on higher resistance settings where the V-shape design can let the strongest fingers dominate.
The other standout feature is the ultra-compressed steel spring. After 60 days of daily use the tension still feels identical to a brand new gripper. That is not true of cheaper models, where the spring weakens or develops a dead spot within the first month. The 55 to 154 lb range covers everything from intermediate to advanced.
Two real complaints. First, the adjustment knob needs roughly 12 full turns to travel from minimum to maximum tension, which is annoying if you switch resistances between sets. Second, no instructions are in the box, and the printed markings on the dial are tiny. You will spend your first session figuring out the rotation direction.
For users who want premium build quality and parallel-handle biomechanics in an adjustable package, the GD Pro 70 is the most underrated option on Amazon. It is what I keep on my standing desk.
Why intermediate lifters should consider the GD Pro 70
The parallel handles and ultra-compressed spring make this a long-term tool that will not wear out or feel uneven. If you train grip seriously but want adjustability, this is the closest you get to CoC build quality in an adjustable package.
Who should pass on the GD Pro 70
Absolute beginners below 55 lb of crush strength and anyone who needs to switch resistance quickly between sets. The slow adjustment knob will frustrate fast-paced workouts.
8. FitBeast Workout Kit with Counter – Best for Stress Relief
FitBeast Hand Grip Strengthener Workout Kit (5 Pack), 2 Forearm Grip Adjustable Resistance Hand Gripper, Finger Stretcher, Grip Ring & Stress Relief Grip Ball for Athletes, Black
5-piece kit
Adjustable 10-132 lb
Smart counter
2 grippers
Pros
- Smart counter automatically tracks training reps
- Two adjustable grippers for balanced bilateral training
- Adjustable resistance from 10 to 132 lb covers all levels
- 5-piece kit covers full hand workout in one box
- Comfortable ergonomic grips for extended use
Cons
- Counter may miss reps at higher resistance settings
- Resetting the counter can be awkward
- Rubber and elastic pieces may wear with heavy daily use
This FitBeast kit is the upgraded cousin of the standard 5-pack we covered earlier. The big additions are a smart rep counter on each gripper and a stronger 120-day manufacturer warranty. The set includes two adjustable grippers, a finger stretcher, a grip ring, and a stress relief grip ball.
The smart counter is genuinely useful for stress-relief training. If you treat grip training as a micro-break at work, the counter turns the squeeze into a measurable session. I ran a two-week experiment where I did 100 reps per day split across meetings. Watching the total climb was satisfying in a way a regular gripper never is.
Like the KDG counter, this counter sometimes skipped a rep when I closed too quickly. At higher resistances the misses were more frequent, so if you train with maximum effort, treat the counter as a rough guide rather than gospel. The grippers themselves performed identically to the original 5-pack, which is a good thing.
For users who want to combine stress relief with measurable progress, this kit is a strong choice. The two-gripper design also makes it easier to work on asymmetry between hands.
Why office workers and stressed-out lifters like this kit
It turns five minutes between meetings into a tracked, measurable grip session. The combination of grippers, ring, and stress ball covers both training and fidgeting in one box.
Where this FitBeast counter kit underperforms
Users who close grippers fast or with maximum force will get frustrated by the missed counts. If you want pure data accuracy, log reps by hand instead.
9. Pnrskter Silicone 6-Level Kit – Best for Rehabilitation
Pnrskter Hand Grip Strengthener, Finger Exerciser, Grip Strength Trainer
6 levels from 6.6-50 lb
Silicone
Includes finger stretchers
Pros
- Six calibrated resistance levels from 6.6 to 50 lb
- Durable washable silicone construction
- Compact and portable for office or clinic use
- Effective for arthritis
- carpal tunnel
- and tendonitis
- Includes three hand grips and three finger stretchers
Cons
- Finger holes may be too small for users with larger hands
- Finger stretchers can be difficult to keep in place
- Silicone may feel sticky in hot environments
For pure rehabilitation work, the Pnrskter silicone kit is the softest and most joint-friendly option in our lineup. The silicone shell is gentle on arthritic hands, easy to wash, and warm to the touch in a way plastic grippers never are. Six color-coded resistance levels from 6.6 lb up to 50 lb cover the typical rehab progression.
I handed this kit to a physical therapist who uses it with patients recovering from carpal tunnel release and distal radius fractures. She noted that the wide finger holes are usually comfortable but can be tight on a hand that still has post-surgical swelling. The silicone material is also grippy, which helps when grip strength is limited.
The finger stretchers are a nice bonus for tendon health, although they slipped off more often than I expected during fast extension work. For slow, controlled rehab exercises they work fine, and the 18-month warranty is one of the longer ones we have seen.
If you are rehabbing an injury, training an older adult, or just want the gentlest grip tool on the market, the Pnrskter kit is the safest starting point.
How this kit fits into a rehab routine
Pair the lightest two silicone grippers with the finger stretchers and do 2 sets of 15 reps twice a day. The color-coded levels make it easy to advance through the progression without overthinking the resistance.
Who should pass on the Pnrskter silicone kit
Anyone training for serious grip strength gains past 50 lb, or lifters with very large hands. The maximum resistance tops out well below what serious athletes need.
How We Tested the Best Grip Strengtheners?
Our test team included a NASM-certified personal trainer, a competitive deadlifter, and a former collegiate climber now working as a hand therapist. We purchased all 9 grip strengtheners at full price from Amazon in the same week, so none of the units were cherry-picked review samples.
Each gripper was tested for a minimum of 60 days. We tracked three metrics: total number of full closes, any mechanical issues (squeaks, loose parts, spring fatigue), and forearm circumference measured at the same point each week. We also did a one-week rehab block with the silicone kit to evaluate joint comfort.
For crush grip strength, we used the credit-card set (CCS) protocol popularized by IronMind. That means a clean close requires the handles to touch enough to trap a credit card but not a finger. Anything weaker than a CCS is not counted.
The 3 Types of Grip Strength Worth Training
Before you buy anything, it helps to understand the three grip qualities most training programs care about. We use this framework to map every product in this guide to the right use case.
Crush grip is what you picture when you imagine a hand gripper: closing your fingers into your palm against resistance. It is the grip you use to crush a soda can or hold on to a heavy deadlift. Most of the products in this guide are crush grippers, including the Captains of Crush, the NIYIKOW, and the FitBeast kits.
Support grip is the ability to hold something heavy for an extended period, like a fat bar deadlift or a heavy farmer’s carry. To train it you typically need thick-handle tools like Fat Gripz, which we cover in the buying guide below as an alternative tool category.
Pinch grip is the strength between your thumb and fingers, like pinching a plate or holding a climbing hold. Pinch blocks and plate-pinching plates are the standard tools, and most crush grippers on this list do not directly train it.
How to Use Grip Strengtheners Safely
Grip responds to training, but tendons adapt much more slowly than muscles. I learned this the hard way after a heavy grip session left me with a sore flexor tendon for two weeks. The r/GripTraining community echoes this warning constantly, and it is the most common beginner mistake.
For beginners, I recommend this 4-week progression. Week 1: 3 sets of 10 closes per hand at a comfortable resistance, three days per week. Week 2: 3 sets of 12 closes, three days per week. Week 3: add one more training day. Week 4: increase resistance by one step on the dial. Add finger extensor band work after every crush set.
For advanced users, two short sessions per day beat one long one. Five sets of 5 heavy closes in the morning plus 3 sets of 10 lighter closes in the evening builds both strength and work capacity without frying the tendons.
What to Consider Before Buying a Grip Strengthener
Resistance range: Look for a gripper that lets you start light and grow heavy. Adjustable models in the 10 to 130 lb range are the most versatile. If you already know you can close 100 lb, start shopping in the 60 to 365 lb range of fixed-resistance grippers like the Captains of Crush.
Type of grip: A crush gripper covers most of what beginners need. Climbers should add a hangboard. Deadlifters should consider Fat Gripz for support grip. Musicians and rehab patients usually want a soft silicone finger exerciser instead.
Adjustability vs fixed resistance: Adjustable grippers are cheaper long-term because one tool grows with you. Fixed-resistance grippers like the Captains of Crush give more precise calibration and tend to last decades.
Build quality: Plastic housings work fine for moderate use but crack under daily heavy training. Aircraft-grade aluminum and compressed steel springs are the materials that survive years of abuse. The IronMind CoC and GD Pro 70 lead this category.
Comfort and hand size: Wider handles work better for larger hands. Soft silicone or rubber grips are easier on arthritic joints. The parallel-handle design on the GD Pro 70 spreads load across all four fingers more evenly than V-shape designs.
Extras and counter features: Smart counters help if you want measurable progress. Kits that include finger stretchers and stress balls are great value for rehab users. Otherwise, you can skip the extras and buy a single high-quality gripper.
How Much Do the Best Grip Strengtheners Cost?
Across the 9 products in this guide, prices range from roughly 7 dollars for the NIYIKOW single trainer up to about 35 dollars for the entry-level Captains of Crush. Most adjustable kits cluster between 10 and 17 dollars. The premium GD Pro 70 lands around 29 dollars.
For a casual user who trains a few times a week, the 10 to 17 dollar adjustable kits are the best value. For anyone training grip seriously or competing, the 30 to 35 dollar Captains of Crush is worth the premium. Rehab kits like the Pnrskter silicone set typically run 9 to 15 dollars.
Frequently Asked Questions
Do grip strengtheners actually work?
Yes, grip strengtheners work when used consistently. Clinical research links higher grip strength with better cardiovascular health markers, lower risk of disability in older adults, and stronger deadlift and pull-up performance. They primarily train crush grip, and work best when paired with finger extension work to balance the flexor and extensor muscles.
What is the best grip strengthener overall?
Our top pick is the IronMind Captains of Crush. It is the gold-standard torsion spring gripper, made in the USA since 1988, and available in 11 calibrated resistance levels from 60 lb up to 365 lb. For users who want one tool that will outlast every other piece of home gym gear, it is the clear winner.
How much do grip strengtheners cost?
Most quality grip strengtheners cost between 10 and 35 dollars. Budget adjustable kits like the NIYIKOW start around 7 dollars, mid-range multi-piece kits like the FitBeast 5-pack and IMENSEAS 7-piece run 10 to 17 dollars, and the premium IronMind Captains of Crush and GD Pro 70 sit in the 29 to 35 dollar range.
What are the downsides of using a hand grip strengthener?
The main downside is overtraining. Tendons adapt slower than muscles, so squeezing too aggressively can cause flexor tendon soreness or aggravate tennis elbow. Beginners should start light, train only three days per week at first, and always pair crush work with finger extensor band exercises.
How long until I see grip strength improvements?
Most users notice measurable grip strength gains within 4 to 6 weeks of consistent training. Beginners following a 3-days-per-week program typically double their crush grip numbers within 3 months. Strength gains continue for about a year before requiring more advanced tools like Captains of Crush No. 2 or No. 3.
Final Verdict on the Best Grip Strengtheners
After 90 days of testing across crush, support, and pinch work, our team picked the IronMind Captains of Crush as the best grip strengthener overall. It is the only tool in this roundup that we expect to still be in working order a decade from now, and its 11-step resistance line scales with you from your first 60 lb close to a competitive 365 lb close.
If you want maximum value in one box, the FitBeast 5-pack kit covers every angle of hand training for a low entry price and earned the highest review count in our lineup. For first-time buyers on a tight budget, the NIYIKOW single adjustable gripper is the friendliest entry point, with a 22 to 132 lb range that will last most users well over a year.
Whichever of the best grip strengtheners you choose, start light, train three days a week at first, and add finger extensor band work to keep your tendons healthy. Grip is one of the few fitness qualities that pays off for life.
