The Grip Strength Test: What It Measures and What It Doesn’t
The short answer
Grip strength is the most-used quick measure of strength in research, because it takes seconds and correlates with how strong you are more broadly. You can test it at home with an inexpensive hand dynamometer: squeeze hard for a few seconds, best of three, same hand, same posture, every time. A European consensus gives reference cut-points of roughly 27 kg for men and 16 kg for women — but treat those as a reason to talk to your provider, never as a self-diagnosis.
It’s the cheapest strength measurement there is, and the most commonly misread. Here’s how to do it properly and how much to conclude from it.
Why grip, of all things
It seems arbitrary until you consider the constraints: a measure needs to be quick, safe, repeatable, and require no skill to perform. Grip is all four, which is why it appears throughout clinical research as a practical marker of whole-body strength rather than an interest in hands specifically.
That’s also its limitation. Grip is a proxy. It correlates with overall strength across groups of people; it does not tell you about your legs, which is where most functional strength lives. Pair it with the sit-to-stand test rather than treating it as the whole picture.
How to test it consistently
You need a hand dynamometer — they’re inexpensive. Sit with your elbow at about ninety degrees and tucked in, wrist neutral, and squeeze as hard as you can for three to five seconds. Take three attempts on the same hand with a rest between, and record the best.
Consistency matters more than technique perfection. Same hand, same chair, same posture, same time of day, ideally not straight after a workout. If you change any of those between tests, you’ve measured the change rather than yourself.
What the cut-points mean
A European expert consensus gives reference values for low grip strength of about 27 kg for men and 16 kg for women. Those numbers get quoted a lot, usually without their context: they sit inside a staged clinical assessment, where a low result prompts further evaluation rather than concluding anything on its own.
So a result under the threshold is not a diagnosis and is not something to panic about — it’s a reasonable thing to mention to your healthcare provider, who can put it alongside everything else they know about you. Equally, a result above it isn’t a clean bill of health. That is genuinely all a home grip test can tell you.
Using it on a GLP-1
Test early, before much weight has come off, so you have a baseline worth comparing to. Then repeat every couple of months under the same conditions and watch the direction of travel — that trend is the useful output, not any single reading.
And if grip does drift down, treat it as information rather than a verdict: check whether your protein has slipped and whether resistance training is still happening, since those are the two levers. If it keeps falling, that’s a provider conversation.
A grip test twice a year is a snapshot; what moves the number is the training in between. Mira builds and scores those sessions through your phone, so the next test has something to show.

How do I test grip strength at home?+
Get an inexpensive hand dynamometer. Sit with your elbow bent to about ninety degrees and tucked in, wrist neutral, and squeeze as hard as you can for three to five seconds. Do three attempts with rests, record the best, and use the same hand, posture and time of day every time. Consistency matters far more than perfect technique.
What is a good grip strength?+
There’s no single good number, and we’d avoid framing it that way. A European consensus cites reference cut-points of roughly 27 kg for men and 16 kg for women, but those are screening thresholds inside a clinical assessment — a low result prompts a professional conversation rather than concluding anything by itself. Your own trend over months is the more useful figure.
Does grip strength show if I'm losing muscle on a GLP-1?+
It gives you a signal, not an answer. Grip is a practical proxy for whole-body strength, which is why research uses it — but it says little about your legs, and strength and muscle mass don’t always move together. Use it alongside the sit-to-stand test and how everyday tasks feel, and take a persistent decline to your healthcare provider.
