Grip strength is one of the more consistently overlooked longevity markers despite being genuinely well-established in the clinical literature, with reference norms like the EWGSOP2 and diagnostic cutoffs used in sarcopenia frameworks like EWGSOP2. It's a strong, well-documented correlate of overall physical function and health outcomes, and unlike many strength metrics, it's trainable through both direct grip work and the compound lifts most programs already include.
- Grip strength has established clinical norms, including EWGSOP2 reference data and EWGSOP2 sarcopenia cutoffs.
- The popular dead-hang duration test is a field-test proxy without a comparable published mortality dataset.
- Compound pulling movements like deadlifts and rows already train grip substantially.
- Direct grip work, dead hangs and farmer's carries, adds further, more targeted stimulus.
Why grip strength is so predictive
Grip strength has repeatedly shown up as a strong correlate of overall physical function, muscle mass, and broader health outcomes across a substantial body of research, part of why it's incorporated into established clinical frameworks like the EWGSOP2 criteria for diagnosing sarcopenia, age-related muscle loss. It's a thoroughly documented marker, not a trendy proxy invented for popular fitness content.
One reasonable explanation for its predictive strength is that grip strength serves as a convenient, easily measured proxy for overall muscular health and neuromuscular function more broadly, someone with strong, healthy muscle tissue and well-functioning nerve-to-muscle signaling tends to have strong grip strength as a natural byproduct, making it a useful, low-effort window into broader physical status.
Grip strength vs. the dead hang test
Worth being precise here, grip strength itself, typically measured with a dynamometer, is the well-established clinical metric with published reference norms and diagnostic cutoffs. The dead hang test, hanging from a bar for as long as possible, is a popular field-test proxy for grip endurance specifically, made popular in some longevity fitness frameworks, but it doesn't have its own published epidemiological mortality dataset the way grip strength measured directly does.
| Grip Strength (Dynamometer) | Dead Hang Duration | |
|---|---|---|
| Clinical reference norms | Yes, EWGSOP2, EWGSOP2 | No formal clinical norms |
| Published mortality dataset | Well-established | Not established |
| Origin | Clinical and epidemiological research | Popular fitness/coaching frameworks |
| Confidence level in Longevity Coach IQ | Higher | Lower, treated as a field-test proxy |
A comparison of evidence base and confidence level for the two measures.
This doesn't mean the dead hang test is useless, it's a reasonable, accessible field benchmark synthesized from coaching and community sources, but it's worth treating with somewhat lower confidence than grip strength measured directly, and not assuming it carries the same weight of clinical evidence behind it.
How to train grip strength
Compound pulling movements you're likely already doing, deadlifts, rows, and pull-ups, provide substantial grip stimulus as a natural byproduct of gripping the bar under load, meaning a well-rounded strength program is already partially training grip without any dedicated work. Adding direct grip training, dead hangs, farmer's carries, or specific grip-strengthening tools, provides further, more targeted stimulus beyond what compound lifts alone deliver.
Farmer's carries specifically are an efficient addition, they train grip endurance under load while also engaging core stability and overall carrying capacity, a useful, functionally relevant exercise beyond grip alone.
The three types of grip, and how to train each
Grip isn’t one capacity. Three distinct types exist, they train differently, and being strong in one says surprisingly little about the others. This is why a gripper-trained hand can still fail on a heavy deadlift.
Crush grip
Closing the hand against resistance, fingers toward palm. This is what a dynamometer measures and what clinical grip strength studies report. Trained by spring-loaded grippers, thick-handled implements and heavy holds.
Support grip
Holding a load for time without it slipping. This is the type most relevant to daily life — carrying shopping, luggage, a toolbox — and the one that fails first on deadlifts and rows. Trained by dead hangs, farmer's carries and simply not using straps for every working set.
The hanging test Longevity Coach IQ uses measures support grip specifically, which is why a good gripper score doesn’t necessarily predict a good hang.
Pinch grip
Holding between thumb and fingers with no wrapping around, as with a plate held by its smooth side. The weakest of the three in most people and the least trained. Relevant mainly to climbing and manual work.
A progression that works
- Dead hangs. Start with accumulated time rather than a single maximum: three to five sets to near failure, aiming at 60 seconds total, then build toward a single 60-second hang.
- Farmer's carries. Two to four sets of 30 to 40 meters with the heaviest load you can hold with good posture. Trains support grip alongside trunk stability and loaded gait.
- Stop using straps on submaximal sets. The single highest-return change for most lifters. Reserve straps for the heaviest work where grip genuinely limits the target muscle.
- Thick grips. Bar attachments or towel-wrapped handles dramatically increase demand. Effective and worth introducing gradually, since they load the hands considerably harder than they appear to.
Frequency and recovery
The forearms recover quickly and tolerate frequent training, but the elbow tendons attached to them don’t. Sudden large increases in grip work are a common route into medial and lateral elbow tendinopathy, and the tendon adaptation timeline applies here as much as anywhere. Two or three dedicated exposures a week, added gradually, is enough.
How to train grip without a separate programme
Coverage treats grip strength as an afterthought, if it is mentioned at all, despite how well established it is in the clinical literature.
Compound lifts do most of the work. Deadlifts, rows and pull-ups build grip as a by-product, and no isolated protocol is needed unless grip is limiting your other lifts.
Add farmer’s carries or dead hangs if you want to accelerate it. A dynamometer reading and a dead hang measure different qualities, so pick the one that matches what you are training.
It tracks grip strength against its actual clinical norms, distinct from the dead hang proxy.

Frequently asked
What is the best dead hang time for longevity?
Thirty seconds is the field benchmark Longevity Coach IQ scores against, and the higher percentile bands run well past a minute. Most untrained people improve quickly here simply because they have never practised the position, which makes it one of the faster markers to move. That thirty-second figure is Longevity Coach IQ’s own benchmark rather than a published threshold, because hanging duration has no equivalent normative dataset.
Is grip strength well-established as a health marker?
Yes, it has established clinical norms, including EWGSOP2 reference data and EWGSOP2 sarcopenia cutoffs.
Is the dead hang test the same as grip strength?
Not quite, it's a popular field-test proxy without its own published mortality dataset, treated with somewhat lower confidence.
How do I train grip strength?
Compound pulling movements like deadlifts and rows already train grip substantially, dead hangs and farmer's carries add further stimulus.
How can I improve my grip strength?
Carry heavy things, hang from a bar, and stop using straps for every set. Farmer's carries and dead hangs are the two highest-return additions, and both fit into sessions you are already doing.
How long should you be able to dead hang?
Thirty seconds is a commonly cited field benchmark, and the top percentiles run considerably longer. Progress here comes quickly at first because most people have never trained the position at all.
Do grip strengtheners work?
Spring-loaded grippers train crushing strength, which is only one of several grip types. They are less useful than simply holding heavy loads for time, because carrying trains the supporting grip that daily tasks actually require.
Why do I lose grip before my back on deadlifts?
Because grip is usually the weakest link in the chain, particularly on higher-rep sets. Using straps for the heaviest work while training grip separately is a reasonable compromise rather than a failure.
Is grip strength linked to mortality?
It is one of the more consistently replicated associations in the literature, most likely because grip reflects overall muscle mass and neurological function rather than doing anything important on its own.
