Grip strength: why it matters and how to fix it

Grip is one of those things you only notice when it quits on you: the bar rolls out of your hands on the fifth rep of a deadlift while your legs and back still had work left in them. But grip isn't just a lifter's detail — hand grip strength is one of the best-studied simple tests of general physical condition. Here's what actually gets measured, what the numbers should be, and how to improve them without equipment you don't own.

What you're actually measuring

Grip isn't one ability, it's three patterns, and they train separately:

• Crush grip — the hand closing around a handle. This is what a dynamometer measures and what most people mean by grip strength.
• Support grip — how long you can hold a load hanging from your hand. This is the one limiting your deadlifts, rows and pull-ups.
• Pinch grip — thumb against the fingers, like carrying two plates pressed together by their smooth sides. For most people this is the weakest link.

On top of that sits forearm extensor strength — the muscles that open the hand. Almost nobody trains them, and the imbalance between flexors and extensors is a common reason for elbow and forearm pain in people who hang and pull a lot.

Why it matters outside the gym

Two reasons, and the second one is more interesting.

The first is obvious: grip is the most common limiting factor in anything you pull. If your set of 5 deadlifts ends because your hand opened, you trained your forearms, not your back. Same for barbell rows, pull-ups and farmer's walks.

The second: grip strength is strongly associated with general health. In a large international study (PURE, roughly 140 thousand participants across 17 countries), every 5 kg of lower grip strength was associated with about a 16% higher risk of death from any cause. It matters what that does and doesn't mean: grip isn't the cause, it's a cheap and fast proxy for total muscle mass, neuromuscular function and activity level. A hand gripper won't extend your life — but a weak grip in your fifties is a reason to look at your overall strength training, not just your forearms.

What counts as normal

The clinical cut-off for weakness (European sarcopenia guidelines) is below 27 kg for men and below 16 kg for women on a dynamometer. A healthy adult average is roughly 45–50 kg for men and 27–31 kg for women, peaking between 25 and 35 years of age and dropping about 1% per year after 50 if you don't train.

No dynamometer? Two equipment-free tests:

1. Dead hang from a bar. Under 20 seconds is weak, 30–45 seconds is average, 60 seconds is solid, over 90 seconds is strong.
2. Farmer's walk. Carry your total bodyweight (half in each hand) for 30–40 metres without setting it down. If that works, grip isn't your problem.

How to train it: 10 to 15 minutes, 2–3 times a week

Grip work goes at the end of a session, never at the start — otherwise it wrecks every pulling set you had planned. Pick 2–3 exercises per day, not all of them at once.

• Dead hang: 4 sets of 20–45 seconds, 90 seconds rest. Once you can do 3 x 60 seconds, add 5 kg on a belt or switch to towel hangs.
• Farmer's walk: 4 sets of 30 metres, starting at 25–30% of bodyweight per hand.
• Plate pinch: two 5 kg plates pressed smooth-side together, 3 sets of 20–30 seconds per hand.
• Barbell wrist curl: 3 sets of 15–20 reps with 10–15 kg, slow, 2 seconds on the way down.
• Banded finger extension: 3 sets of 20–25 reps. This is the balancing work for the extensors — do it every session.

Progression is boring and it works: add 5 seconds or 2.5 kg per week for as long as it keeps moving, then reset to 80% and climb again. A realistic expectation is 15–25% improvement in dead hang time over 8–12 weeks.

Forearms recover fast, tendons don't. Leave at least 48 hours between hard grip days, and don't put one the day before a heavy deadlift session.

Lifting straps: when yes, when no

Straps aren't cheating, but they are an excuse if you put them on every set. Practical rule: first 1–2 working sets strapless, straps for your heaviest set above 85% of max and for sets of 8 or more reps where grip would fail before your back does. A mixed grip solves slipping, but always mixing the same way builds asymmetry — alternate hands every set.

Three mistakes you see constantly

• Training grip at the start of a session, then wondering why the rows felt heavy.
• Only closing the hand, never opening it. A 3:1 ratio in favour of the flexors is a recipe for forearm pain.
• A little bit every single day. Forearms tolerate a lot, but tendons accumulate fatigue quietly and send the bill 6–8 weeks later.

When to see a doctor

A weak grip is usually a training issue. These aren't:

• Tingling, burning or numbness in the fingers, especially at night or in the thumb, index and middle finger — this can be carpal tunnel syndrome.
• Sudden weakness in one hand only, or dropping objects for no clear reason.
• Pain lasting more than 2–3 weeks despite rest, or morning stiffness in the hands lasting more than 30–45 minutes — that points toward inflammatory conditions, not overload.
• Swelling, redness or warmth in the finger joints.
• Anything following a fall onto an outstretched hand. A scaphoid fracture is often missed because it hurts surprisingly little in the first days.

If grip weakens in both hands at once and you haven't changed your training, that's not a local forearm problem — it's a reason to get checked.

The short version

• Grip has three separate patterns — crush, support and pinch. Train all three, not just squeezing.
• The weakness threshold on a dynamometer is under 27 kg for men and under 16 kg for women; without one, use the dead hang (target 60 seconds) and a bodyweight farmer's walk for 30 metres.
• 10–15 minutes at the end of a session, 2–3 times a week, 2–3 exercises per day, always including banded finger extensions.
• Straps on your heaviest set, not every set; alternate sides if you use a mixed grip.
• Tingling, one-sided weakness, morning stiffness over 45 minutes, or a fall onto the hand — that's a doctor's job, not more sets.
