There's a moment every lifter eventually hits: the weight is there, the legs and back have it, but the hands give out first. The deadlift bar rolls out of the fingers at 90% of max. The farmer's walk drops early. The pull-ups end not because the lats are done, but because the forearms are. The grip becomes the ceiling — and everything else is limited by it.
Grip strength is the most commonly undertrained physical quality in strength sports. It's undertrained because it develops passively from regular lifting to a point — and then stops developing without targeted work. Most athletes coast through years of training with grip at 60–70% of what it could be, and never realise how much performance they're leaving on the floor.
This guide covers what grip strength actually is, why it matters, the tools that build it, and a complete integration plan for adding grip work to any training programme.
What Is Grip Strength — and Why Does It Transfer to Everything
Grip strength can be separated into three main types: crushing grip, pinching grip, and support grip.
Crushing grip is your handshake grip — the force you generate when closing the fingers against resistance. This is what a hand gripper trains. It's what you use to hold a bar during a deadlift, a handle during a farmer's walk, or an opponent during a grappling match.
Pinching grip is thumb-and-finger force — picking up a plate by the rim, crimping a climbing hold, grabbing a sandbag. It trains different muscles than crushing grip and requires specific tools to develop.
Support grip is the endurance component — how long you can maintain a hold under load. Farmer's carries, dead hangs, and barbell holds train this. It's the quality that determines whether you make it to the end of a long carry event or whether your hands give out at the 25-metre mark.
All three are trainable. All three transfer directly to barbell strength, strongman performance, climbing, grappling sports, and athletic performance broadly.
Studies have shown that grip strength is strongly correlated with cardiovascular health — in fact, a strong grip has been shown to be a better predictor of cardiovascular health than traditional measures like blood pressure and cholesterol levels. This isn't just a curiosity — it reflects the fact that grip strength is a reliable proxy for overall muscular development and systemic health.
According to a 2011 report, grip strength is a powerful predictor of overall muscle strength. For practical training purposes, this means: improve grip, and the strength it unlocks across your other lifts is real and measurable.
Who Needs Dedicated Grip Training
The short answer: anyone whose sport involves holding something.
Powerlifters — deadlift grip is the most common limiting factor outside of leg and back strength. Most lifters add 25–50 lbs to their max deadlift through dedicated grip training. That's a meaningful number.
Strongman and Strongwoman athletes — strongmen can't carry 1,050 pounds up an inclined ramp without powerful grip training, let alone pretty much every other challenge they face. The farmer's walk, axle deadlift, and loading medley are all grip-limited events at high loads.
Olympic weightlifters — the hook grip is a technique solution to a grip problem. Stronger hands mean a more secure hook grip, better barbell control in the snatch, and safer catching in the clean.
Climbers — rock climbers can't ascend a challenging route without impressive grip strength. Every hold requires a combination of crushing and pinching grip that no other sport replicates.
Grapplers (BJJ, judo, wrestling, MMA) — a strong grip allows you to execute techniques more efficiently — whether applying a rear-naked choke or an armbar, a robust grip lets you control your opponent's movements with precision.
Functional fitness athletes — any format that includes barbell cycling, gymnastics, carry events, or high-rep pulling movements is limited by grip endurance.
General strength athletes — even if none of the above apply directly, grip training prevents the common situation where accessory movements — rows, pull-ups, barbell work — end early because of forearm failure rather than target muscle failure.
The Three Types of Grip Tool and What Each Develops
Grippers — Crushing Grip
A gripper is a spring-loaded resistance tool that closes between the palm and fingers. Simple in concept, specific in effect: it trains the finger flexors, thumb flexors, and forearm muscles responsible for generating and maintaining crushing force.
Strength Shop Black Grippers — 100 to 300lbs (45–136kg)
The practical entry point. Available across a range of resistances from 100lbs (45kg) up to 300lbs (136kg), these grippers cover the spectrum from beginner to advanced crushing strength. The principle of progression with grippers is simple: when you can close a gripper for 10–15 clean reps, move to the next resistance level. What looks like a small jump in numbers on the packaging often represents a meaningful step up in difficulty — especially in the 200–300lb range.
The key technical point: a gripper rep is only a full rep when the handles make complete contact. Partial closes build partial strength. Train through the full range of motion.
Captains of Crush Hand Grippers
The benchmark. Captains of Crush grippers are the original, authentic, unmatched gold standard for building and testing grip strength — available in 11 strengths, from beginners through to athletes who can already crack coconuts with their bare hands.
The full CoC progression:
| Gripper | Resistance | Context |
|---|---|---|
| Guide | 60 lb | Beginners, rehab |
| Sport | 80 lb | Active non-grip-trained athletes |
| Trainer | 100 lb | General starting point |
| Point Five | 120 lb | Bridge to No.1 |
| No. 1 | 140 lb | Strong recreational level |
| No. 1.5 | 167.5 lb | Bridge to No.2 |
| No. 2 | 195 lb | Elite level |
| No. 2.5 | 237.5 lb | Bridge to No.3 |
| No. 3 | 280 lb | World-class |
| No. 3.5 | 322.5 lb | Bridge to No.4 |
| No. 4 | 365 lb | Held by only a handful of people on earth |
As of 2026, just over 200 athletes have been certified on the Captains of Crush No. 3, including elite competitors like Brian Shaw, Magnus Samuelsson, Jedd Johnson, and Andrew Durniat. It is the only widely recognised standard for this level of achievement in grip sport.
Closing the No. 3 under official conditions — set grip, witnessed close, handles touching — is a genuine athletic achievement that takes most dedicated grip athletes several years of structured training. Most competitive strength athletes will spend their careers in the No. 1 to No. 2 range, which already represents grip strength well above the average gym-goer.
For most powerlifters and strongman athletes, the No. 1 (140lb) to No. 2 (195lb) range is the practical training target. Achieving a clean No. 2 close means your crush grip is no longer the limiting factor in any standard barbell or carry event.
Thick Implements — Crushing and Support Grip Under Load
One of the most effective — and most overlooked — methods for developing grip strength is simply making the bar thicker. A standard barbell is 28–29mm in diameter. A human hand can wrap around that with relative ease. Increase the diameter and everything changes: the fingers can no longer fully wrap, the grip becomes a partial crimp, and the forearm musculature has to work significantly harder to maintain the same hold.
Thick grips are rubber sleeves that slide over a standard barbell, dumbbell, or cable attachment to increase the diameter. The conversion is instant — any standard barbell becomes a thick bar implement without purchasing dedicated thick bar equipment.
Exercises done with thick grips that produce immediate grip development:
- Barbell rows
- Pull-ups and chin-ups
- Dumbbell curls
- Deadlifts
- Barbell shrugs
- Cable rows
The thick grip converts every pulling movement into a grip training movement simultaneously. The target muscles still get trained; the grip gets an additional challenge on top. This is one of the most efficient grip training methods available because it adds no extra time to the session.
The axle bar — also called a thick bar — is a solid steel barbell with a 50mm diameter shaft rather than the standard 28–29mm. At 50mm, the grip challenge is substantial: no conventional hook grip is possible, and maintaining a hold on heavy deadlifts, rows, or carries requires significantly more forearm and hand strength than a standard bar.
The axle bar is a staple of strongman training — axle deadlifts and axle clean and press are standard strongman events. For athletes preparing for strongman competition, training the axle deadlift specifically (double overhand, no straps) is both a competition-specific preparation and a grip development method simultaneously.
For non-competitive athletes, the axle bar is one of the best grip development tools available — the 50mm diameter forces the hand into a grip position that standard bars never train.
Solid Steel Axle Dumbbell Handle
The axle dumbbell handle brings the thick bar concept to unilateral training. Single-arm rows, dumbbell curls, farmers walk handles, and loaded carries done with a 50mm dumbbell handle address the grip at a different angle than the barbell — and allow the weaker hand to be trained independently.
For grip imbalances — where one hand is significantly stronger than the other — the axle dumbbell handle is the most effective correction tool.
Extensor Training — The Overlooked Balance
Hand grippers and thick bars train the flexors — the muscles that close the hand. The extensors — the muscles that open the hand — are rarely trained directly. This creates an imbalance that over time contributes to finger and wrist injuries, tendonitis in the forearm, and reduced grip endurance.
Expand-Your-Hand bands provide resistance for opening the fingers and hand against load. The movement is simple: place the band around the fingers, open the hand against resistance. It's a five-minute addition to any session that directly counteracts the imbalance produced by gripper and bar work.
For athletes with high grip training volume, or for anyone who has experienced finger tendonitis or forearm tightness, extensor work is as important as the crushing and pinching work that causes the imbalance.
Chalk — Grip Support
Chalk reduces moisture on the hands, increasing friction between skin and bar. This is not grip training — it's grip support. Chalk doesn't make the hands stronger; it removes a variable (moisture) that would otherwise reduce performance below the actual strength level of the hand.
Use chalk for max deadlift sets, heavy barbell rows, and any pulling movement where sweat becomes a factor. The liquid format dries quickly, produces less dust than block chalk, and is appropriate for gym environments where loose chalk is restricted.
The Grip Training Integration Plan
For Powerlifters and Strength Athletes
Goal: Eliminate grip as the limiting factor in the deadlift and carry events. Build to a No. 2 CoC close.
Weekly structure:
Session 1 (after deadlift day):
| Exercise | Sets | Reps/Duration | Notes |
|---|---|---|---|
| Double-overhand deadlift hold | 3 | 30–45 sec max hold | Last set of deadlift session, no straps |
| Thick grip barbell row | 3 | 8–10 | Thick grips on working sets |
| CoC gripper — working resistance | 3 | 5–8 full closes | 2 levels below max |
| CoC gripper — near-max | 3 | 1–3 | At or near max closeable level |
Session 2 (separate, 2–3 days later):
| Exercise | Sets | Reps/Duration | Notes |
|---|---|---|---|
| Axle deadlift — double overhand | 4 | 3–5 | 60–70% of barbell max, no straps |
| Plate pinch carry | 3 | 20m | Two plates pinched face-to-face |
| Expand-Your-Hand bands | 3 | 20 | Open fully against resistance |
| Gripper negatives | 3 | 5 | Open with both hands, close with one |
Progression: Move to the next gripper level when 3 sets of 8 clean full closes is achievable. Add 2.5kg to axle deadlift when all reps are completed double overhand.
For Strongman Athletes
Goal: Competition-specific grip for axle deadlift, farmer's walk, loading events.
Session A — Axle Focus:

| Farmer's walk | 4 | 30m | Heavy; put bar down only if required |
| CoC No. 2 or 2.5 — max reps | 4 | Max | Test strength regularly |
Session B — Volume and Endurance:
| Exercise | Sets | Reps/Duration | Notes |
|---|---|---|---|
| Axle dumbbell single-arm row | 3 | 10/side | Grip focus |

| Axle dumbbell carry | 3 | 40m | Both hands, heavy walk |
| Expand-Your-Hand bands | 2 | 25 | Session finish |
For Beginners — Building the Foundation
If grip training is new, start here before moving to the sport-specific protocols:
| Week | Tool | Work |
|---|---|---|
| 1–2 | Black gripper (100–150lb) | 3×10 both hands, daily |
| 3–4 | Thick grips on pulling movements | Add to all rows and pull-ups |
| 5–6 | Introduce CoC Sport or Trainer | 3×5 max closes, 3×day |
| 7–8 | Add extensor work | Expand-Your-Hand bands, 3×20 |
| 9+ | Progress gripper level + add axle work | Follow sport-specific protocol |
Practical Notes on Gripper Training
Don't train grippers to failure every session. The forearm flexors recover slowly. Training grippers every day at max intensity leads to overuse injuries — finger pulleys, tendonitis, and forearm pain that can take months to resolve. Three to four sessions per week with adequate rest between max-effort sessions is the correct frequency.
The set position matters. For Captains of Crush and quality grippers, the "set" refers to the starting position of the gripper in the hand before closing. A deep set (gripper placed further into the palm) allows more mechanical advantage at the beginning of the close. A sport/competition close typically requires a standard set position. Both are valid training positions — just understand what you're training.
Negatives are one of the best gripper exercises. Open the gripper with two hands, transfer to one, and resist as the gripper opens slowly. The eccentric (opening) phase builds strength that accelerates progress on the concentric (closing) phase. For athletes stuck between gripper levels, negatives are often the breakthrough tool.
Chalk is appropriate for heavy gripper work. For max close attempts and near-max work, liquid chalk on the hands provides the same friction benefit it does on a barbell.
The Short Version
Grip strength limits performance in deadlifts, carries, pulling movements, grappling, climbing, and every sport that involves holding something under load. It responds quickly to targeted training, and the tools required are compact and inexpensive relative to every other piece of strength equipment.
The Strength Shop grip collection covers every category: crushing grip from beginner to world-class via grippers and the Captains of Crush line, thick implement work via thick grips and the axle bar, unilateral grip via the axle dumbbell handle, and extensor balance via the Expand-Your-Hand bands.
