Choosing the Right Gripper Resistance Level for Beginners
This article is for anyone standing in front of a gripper selection, or staring at a product page, wondering whether the Trainer, the Sport, the #1, or the HG200 is the right place to start. The honest answer is that most beginners buy a gripper that is too heavy, get frustrated when they cannot close it, and either push through with bad form or quit. A smaller number buy one that is too easy, breeze through every session, and wonder why nothing is changing. Both outcomes are avoidable.
Here you will find a clear breakdown of the two main gripper lines (Captains of Crush and Heavy Grips), a practical rule for choosing two grippers instead of one, a no-equipment self-assessment to identify your starting level, and specific criteria for when it is time to move up. If you want the broader equipment context first, the Grip Tool Starter Path covers how grippers fit into the full stack at every budget level.
The Two Main Gripper Lines
Hand grippers in the serious grip training world fall into two dominant brands. Everything else (the spring grippers from sporting goods stores, the adjustable plastic models) is in a different category and not what this article covers. If your gripper came in a blister pack for $6, the resistance ratings below will not apply to it.
Captains of Crush (IronMind): The industry standard for over 30 years. Fixed resistance, aluminum handles, high-quality coil springs. The rating system runs from the Guide (60 lb) up to the #4 (365 lb). Certification is available for closing the #1.5 and above, which is why CoC grippers serve as a benchmark for the entire grip strength community. The progression is well-documented, the ratings are consistent batch to batch, and the CoC #1 and #2 function as broadly recognized standards for intermediate and advanced grip strength. The full history and progression details are covered in the Captains of Crush Progression Ladder.
Heavy Grips: A popular and less expensive alternative with a simpler naming system, the number in the name reflects the rated resistance in pounds (HG100, HG150, and so on up to HG350). Heavy Grips use a similar fixed-resistance design. The ratings are roughly comparable to CoC, though the feel and spring characteristics differ slightly. Heavy Grips work well as working grippers, particularly if budget is a consideration at the entry level.
Both lines are legitimate training tools. The choice comes down to whether you want the CoC certification pathway and benchmark system, or a more economical working gripper at your starting resistance.
The Two-Gripper Rule
Most gripper advice focuses on a single question: which one should I buy? That framing is the source of most beginner mistakes. The more useful question is: which two should I buy?
The Two-Gripper Rule is simple: you need a working gripper and a goal gripper.
- Working gripper: The one you actually train with. You can close it for multiple reps with controlled form. It produces a real training stimulus: not easy, but not a maximum effort on every rep either. Most sessions use this gripper for the bulk of your sets.
- Goal gripper: One step above your working gripper. You might not be able to close it yet, or you can just barely close it once under ideal conditions. You use it occasionally for singles, partial reps, or overcoming-isometric attempts to train the range of motion above your current strength. It also keeps you honest about where you are headed.
The reason this matters: grip strength adapts in small increments. If you only own your working gripper, you have no way to train the strength you do not yet have, and no clear target to work toward. The goal gripper is not for ego; it is a training tool for developing the top end of your current range. When the goal gripper becomes closeable for five clean reps across two sets at an RPE of 7 or below, your working gripper has become too easy and it is time to move both grippers up one level.
The Grip Tool Starter Path covers how to build this two-gripper setup into your initial equipment budget.
Captains of Crush Resistance Levels
The CoC line has eleven levels. Most beginners should be looking at the Guide through the Trainer range; the #1 and above are intermediate to advanced territory for most people. The percentage column below reflects roughly how many untrained or lightly trained adults can close each gripper from a legal set position, meaning the spring is set with both handles parallel, fingers positioned correctly, and the close completed to full contact without any cheating the set.
| Gripper | Rated Force | Recommended For | Approx % That Can Close (Untrained) |
|---|---|---|---|
| Guide | 60 lb (27 kg) | Rehabilitation, elderly, very low starting grip | ~90% |
| Sport | 80 lb (36 kg) | True beginners, smaller hands, returning from hand injury | ~80% |
| Trainer | 100 lb (45 kg) | Most beginners; good working gripper for the first 2–4 months | ~65% |
| #0.5 | 120 lb (54 kg) | Beginners who have trained a few months; bridge between Trainer and #1 | ~50% |
| #1 | 140 lb (64 kg) | Intermediate: a real milestone; roughly average for trained adult males | ~30% |
| #1.5 | 167.5 lb (76 kg) | Intermediate-advanced; lower threshold for IronMind certification | ~15% |
| #2 | 195 lb (88 kg) | Advanced; elite general population, competitive grip sport entry level | ~5% |
| #2.5 | 237.5 lb (108 kg) | Very advanced; serious grip competitors | ~2% |
| #3 | 280 lb (127 kg) | Elite grip strength; fewer than 200 certified closers in IronMind history | <1% |
| #3.5 | 322.5 lb (146 kg) | World-class; extremely rare | <0.1% |
| #4 | 365 lb (166 kg) | The hardest production gripper; fewer than a handful of verified closes ever | <0.01% |
A few notes: the Trainer is the right working gripper for most beginners, not the #1. The #1 is a milestone goal, but if you cannot close it cleanly for reps, it belongs in the goal gripper slot, not the working gripper slot. Hand size also matters: people with smaller hands will find CoC grippers harder to close at equivalent rated resistance because handle span affects leverage. The Sport is worth considering as a starting point for smaller hands regardless of general fitness level.
Heavy Grips Resistance Levels
Heavy Grips uses a simpler system: the resistance in pounds is in the name. If you are comparing to CoC, the ratings are roughly equivalent, though the spring characteristics differ. HG grippers tend to feel slightly stiffer through the middle of the range of motion than CoC at comparable rated weights.
| Gripper | Rated Force | Recommended For |
|---|---|---|
| HG100 | 100 lb (45 kg) | Beginners; comparable to CoC Trainer; solid working gripper to start |
| HG150 | 150 lb (68 kg) | Early intermediate; slightly above CoC #1; use as goal gripper after a few months |
| HG200 | 200 lb (91 kg) | Intermediate; comparable to CoC #2; working gripper for strong intermediates |
| HG250 | 250 lb (113 kg) | Advanced; comparable to CoC #2.5; serious grip trainees only |
| HG300 | 300 lb (136 kg) | Elite; comparable to CoC #3 range; competitive grip athletes |
| HG350 | 350 lb (159 kg) | World-class; maximal resistance in the Heavy Grips line |
For most beginners, the HG100 is the starting working gripper and the HG150 is the first goal gripper. If you already have some grip strength from manual labor or climbing, consider the HG150 as your working gripper with HG200 as the goal gripper.
How to Self-Assess Your Starting Level
You do not need a gripper to estimate your starting resistance. The tests below give you a practical baseline that maps to the tables above. Do these before buying anything; they will tell you whether you should be starting with a Trainer/HG100 or whether you can jump straight to the #0.5 or #1 range.
Test 1: The Grocery Bag Hold
Load a bag with two large water bottles (roughly 8–10 lb total) and carry it by the handles with one hand for 60 seconds. Noticeable forearm fatigue before 30 seconds? Start with the CoC Sport or Guide. Completed without trouble? Move to Test 2.
Test 2: The Timed Dead Hang
Hang from a pull-up bar with a shoulder-width overhand grip until your grip fails. Under 20 seconds: start with the CoC Sport or Trainer. Twenty to 45 seconds: Trainer to #0.5 range. Forty-five seconds or more: the #0.5 or #1 is a realistic near-term goal, with the Trainer as your working gripper.
Test 3: The Towel Wring Test
Wring out a wet towel with both hands in opposite directions for five seconds. Forearm fatigue? You are in the beginner range, Trainer or below. If it feels easy, you have some baseline forearm development and can target the #0.5 or #1 as a medium-term goal.
Mapping Your Results
| Self-Assessment Result | Recommended Working Gripper | Recommended Goal Gripper |
|---|---|---|
| Dead hang under 20 sec, or forearm fatigue on grocery carry | CoC Sport (80 lb) / HG100 | CoC Trainer (100 lb) |
| Dead hang 20–45 sec, grocery carry complete but challenged | CoC Trainer (100 lb) / HG100 | CoC #0.5 (120 lb) or HG150 |
| Dead hang 45+ sec, towel wring and carry easy | CoC #0.5 (120 lb) or HG150 | CoC #1 (140 lb) or HG150 |
| Manual labor background, climbing, or structured strength training | CoC #1 (140 lb) or HG150 | CoC #1.5 (167.5 lb) or HG200 |
These tests are directional, not clinical. When in doubt, start with the lower working gripper; tendon irritation is the most common early setback in gripper training, and it almost always comes from starting too heavy.
Common Mistakes When Choosing a Gripper
These mistakes come up constantly. Most cost people weeks or force them to back down after accumulating tendon stress.
- Buying the #1 as your first gripper. Closing the #1 cleanly is a real milestone, but if you cannot close it for five reps, it is a goal gripper, not a working gripper. Training on something you can barely close once does not build strength; it builds tendon irritation.
- Owning only one gripper. One gripper means one intensity option. You cannot warm up properly, accumulate volume, or train toward anything. The Two-Gripper Rule exists because one gripper is not enough.
- Abandoning the working gripper too early. The moment the goal gripper becomes closeable, people stop training the working gripper. The working gripper is where volume and foundation are built. Skipping it produces a fragile one-rep close that never develops into real training capacity.
- Deep palm set instead of legal position. Setting the gripper deep in the palm adds mechanical advantage, making it easier to close but training the wrong position. Legal set means the top handle sits just below the first knuckle of the index finger. If you only close from a deep palm set, drop down one level.
- Training to failure every session. Tendons need progressive loading, not constant maximal stress. Leave one to two reps in reserve per set, especially in the first four to six weeks.
When to Move Up
Skip "it feels easier"; too much room for wishful thinking. Use this instead:
Move up when: you close your current working gripper for 5 reps × 2 sets from a legal set position, at an RPE of 7 or below, on two consecutive sessions in the same week.
RPE 7 means at least three reps left in the tank at the end of each set. If the fifth rep was a grind, that is RPE 9 or 10. When the standard is met, the goal gripper becomes your new working gripper and you buy one level up as the new goal gripper.
Timing check: Allow at least eight weeks between upgrades in your first year. Muscles may be ready before tendons are. If you hit the RPE and rep standard at six weeks, add a set per session rather than immediately upgrading; tendons need the extra adaptation time.

Frequently Asked Questions
What is the right first gripper for a beginner?
For most people starting from scratch, the CoC Trainer (100 lb) or Heavy Grips HG100 is the right working gripper. The CoC Sport (80 lb) is appropriate for people with smaller hands, lower baseline strength, or those returning from a hand injury. The #1 is not a beginner gripper; it is an intermediate milestone. If you want a two-gripper setup from day one, pair the Trainer with the #0.5 or the HG100 with the HG150.
Are Captains of Crush and Heavy Grips rated the same way?
Both measure peak closing force in pounds, but the feel differs. CoC has a smoother resistance curve; Heavy Grips tend to feel stiffer mid-range. Training stimulus is similar at equivalent ratings. The main practical differences are price (Heavy Grips are typically cheaper) and the CoC certification program for the #1.5 and above, which Heavy Grips does not offer.
Can I start with an adjustable gripper instead of a fixed-resistance one?
Adjustable grippers cover multiple resistance levels in one tool, but budget models tend to have inconsistent resistance between settings and a different feel from a quality close. For budget reasons they can work, but two fixed-resistance grippers from CoC or Heavy Grips give you more consistent benchmarks and better training quality.
How many days per week should I train with a gripper?
Three days per week with at least one full rest day between sessions is the standard starting frequency. Grip tendons need roughly 48–72 hours to recover from a working session, and new trainees consistently underestimate how much stress gripper training places on the flexor tendon system. If your forearm feels persistently tight or tender, drop to two sessions per week until it clears. For the full frequency breakdown by goal and experience level, see the Grip Training Encyclopedia.
I can almost close the CoC #1. Should I skip the Trainer and go straight to #1?
"Almost closing" the #1 means it is your goal gripper, not your working gripper, which is exactly the Two-Gripper Rule situation. Buy the #1 as your goal gripper and the Trainer or #0.5 as your working gripper. Volume on the working gripper builds the foundation for a clean, repeatable #1 close. Training exclusively on a gripper you can barely close for one rep produces slow progress and a higher risk of tendon irritation.
Pick Your First Gripper
Use the self-assessment above to identify your starting level, then apply the Two-Gripper Rule: one working gripper you can train with for sets and reps, one goal gripper one level above. That is the complete beginner setup, no more complicated than that.
