At some point, you’ve probably opened a stubborn jar and immediately wondered whether the lid was glued on by a bored factory worker with something to prove.
Or maybe you’ve carried all the grocery bags from the car to the kitchen in one trip because making two trips is clearly a moral failure.
Either way, you’ve experienced the practical value of grip strength.
But grip strength isn’t only useful for daily tasks or carrying your suitcase on vacation. It also seems to be a surprisingly useful marker of overall health.
What researchers have discovered about grip strength
Researchers often use handgrip strength as a simple way to assess general muscle function. That may sound strange at first because the test itself is so simple and seemingly inconsequential: squeeze a handheld device called a dynamometer as hard as possible for a few seconds, and it records the force you produce.
But despite its simplicity, grip strength seems to tell us more than we might expect.
In a recent study of more than 9,500 U.S. adults, researchers found that lower handgrip strength was associated with a higher risk of all-cause mortality. Interestingly, the simplest measurements—how hard someone could squeeze in absolute terms—were among the best predictors.
That doesn’t mean grip strength magically determines lifespan.
It more likely means grip strength reflects a variety of things that matter as we age: muscle mass, nervous system function, activity level, nutrition, and the ability to keep doing normal human tasks like lifting, carrying, pulling, and catching ourselves when we stumble.
Grip strength is a marker, not magic
This distinction matters because once a measurement becomes associated with health, it’s easy to over-focus on improving the measurement itself.
That’s how we end up with people obsessing over step counts while avoiding actually walking outside, chasing sleep scores while stressing themselves awake, or buying grip trainers and squeezing them while sitting motionless—all in the name of “longevity”.
Grip strength is useful as a marker because it reflects broader physical capacity. If your grip is strong because you regularly lift, carry, climb, hang, and pull, that’s meaningful. If it improves only because you squeeze a plastic gripper while doing nothing else, that might still be better than nothing—but it probably doesn’t carry the same long-term health implications.
In other words, the goal isn’t to create stronger fingers in isolation. It’s to develop the kind of body that has strong hands because it regularly does physically challenging things.
The real-life value of stronger hands
Grip strength also matters because it shows up constantly in everyday life.
You use it when you:
- Carry groceries
- Pick up kids or grandkids
- Open jars
- Shovel snow
- Move furniture
- Carry luggage
- Pull yourself up from the floor
- Hold a leash when your dog spots a squirrel
- Catch yourself when you trip
That last one is worth emphasizing.
As we age, one of the major concerns isn’t just whether we can lift something heavy in the gym. It’s whether we can confidently interact with the world and recover when something unexpected happens.
If you slip on ice, stumble on a trail, or lose your balance while carrying something cumbersome, your hands may be the first thing that connects you to a railing, wall, branch, countertop, or another person.
The stronger and more capable your grip, the better chance you have of turning a potential fall into an awkward little dance move that you pretend was intentional.
While grip strength alone won’t prevent every problem, it’s part of a much larger picture of maintaining strength, coordination, independence, and confidence as we age.
How to train grip strength without overcomplicating it
Unless you’re a climber or martial artist who really wants to take your grip to a highly specialized level—a topic for another time—improving grip strength doesn’t require a dedicated program.
You mostly need to spend more time holding, carrying, hanging from, and lifting things using your hands.
A few good options include:
- Farmer carries or dead hangs
- Rows or pull-ups (assisted or not)
- Deadlifts
- Kettlebell swings, cleans, and snatches
- Playful activities like rock climbing or grip-oriented martial arts practice (e.g. judo, jiu-jitsu, wrestling)
You can certainly use dedicated grip tools if you enjoy them—hand and forearm muscles do respond to focused training like any other muscle group—but they shouldn’t replace full-body training. The goal isn’t just stronger hands. It’s becoming a stronger person whose hands reflect that strength.
Putting it into practice
This week, add one grip-focused element to a couple of your training sessions.
For example, at the end of a workout you might:
- Carry a pair of kettlebells or dumbbells, or hang from a pullup bar (the linked tip above includes specific recommendations for both)
- Hold the final rep of a deadlift or row for a few extra seconds
- Swing some heavy Indian clubs
- Squeeze some grippers between sets of a non-grip-demanding exercise (e.g. bench press, back squats)
- Or unload and put away the weight plates that the last person left on the squat bar
Keep it simple: choose something that challenges your grip while still allowing good posture, controlled breathing, and reasonable technique.
Over time, a stronger grip should improve your comfort and confidence with heavier lifting—which helps build the broader physical capacity needed to handle everyday life and age well.
And as a bonus, you’ll be ready the next time a jar lid puts up a fight—unless the factory worker was really bored.
