Grip Strength and Aging: Why It Matters and How to Improve It
Doctors and researchers can learn a surprising amount from how hard you squeeze a handle. Grip strength takes seconds to measure, needs nothing more than a handheld dynamometer, and is widely used in research as a quick snapshot of muscle strength. That is why it shows up in so many large aging studies, and why it is worth paying attention to long before retirement.
Here is what the research says about how grip strength changes across your life, what a weaker grip is associated with, and the training and nutrition habits that help you keep it.
Key Takeaways
- In 49,964 British adults and children, grip strength peaked around a median of 51 kg in men and 31 kg in women, held through midlife, then declined.
- In the 17-country PURE study, every 5 kg lower grip was associated with a 16% higher risk of death from any cause over a median of 4 years.
- Those findings are associations: they show grip is a useful marker, not that squeezing a gripper extends life.
- Exercise training produces small but real grip improvements in older adults, especially task-specific and multimodal programs.
- Creatine plus resistance training has been shown to add lean mass and upper and lower body strength in older adults.
What Is Grip Strength and Why Does It Matter?
Grip strength is the maximum force your hand can produce squeezing an object. It is usually tested with a dynamometer, and because it is fast, cheap and repeatable, it has become a go-to measure in large population studies.
One of the largest is the Prospective Urban Rural Epidemiology (PURE) study, published in The Lancet in 2015. Researchers measured grip in 139,691 adults across 17 countries and followed them for a median of 4 years. Every 5 kg lower grip strength was associated with a 16% higher risk of death from any cause and a 17% higher risk of cardiovascular death.
It is important to read that correctly. PURE is an observational study. A weaker grip is likely a signal of lower overall muscle strength, fitness and health, not a cause of risk on its own. Nobody has shown that training your forearms alone changes long-term outcomes. What it does tell you is that whole-body strength is worth protecting as you age, and grip is an easy way to keep score.

How Grip Strength Changes With Age
A detailed picture of how grip changes across a lifetime comes from Dodds and colleagues, who pooled 60,803 measurements from 49,964 people in 12 British studies covering ages 4 to 90. Grip rose to a peak in early adulthood, held steady through midlife, then declined.
| Group | Peak median grip | Age range of peak | % with weak grip at 80 |
|---|---|---|---|
| Men | 51 kg | 29–39 | 23.0% |
| Women | 31 kg | 26–42 | 26.6% |
"Weak grip" here means a T-score of −2.5 or lower: at least 2.5 standard deviations below the peak mean for the same sex. The authors also noted that at age 25, men's median grip was about 1.6 times women's, rising to about 1.7 times from age 50, so compare yourself with your own sex and age group rather than a single number.
How to Improve Grip Strength
The good news: grip responds to training, including in older adults. A 2019 meta-analysis by Labott and colleagues pooled 24 trials with 3,018 healthy older adults (average age about 73). Exercise training produced a small but significant improvement in grip strength. The authors found that task-specific training and multimodal programs seemed to provide the best stimulus, and cautioned that grip alone does not capture every benefit of an exercise program. In other words, train your grip directly and keep training everything else.
1. Lift Heavy Things With Your Hands
Deadlifts, rows, pull-ups and Romanian deadlifts all load your grip. Do your warm-up and working sets without straps whenever your grip can handle the weight, and save straps for the heaviest top sets.
2. Add Loaded Carries
Farmer's carries load your grip under real-world conditions. Pick up a pair of heavy dumbbells or kettlebells, stand tall and walk 30–40 meters. Two to four rounds at the end of a session is plenty.
3. Hang From a Bar
Dead hangs build support grip and give your shoulders a stretch. Start with a few sets of 20–30 seconds and build the total time each week.
4. Train Pinch and Crush Grip
Plate pinches (holding two smooth plates together) and hand grippers hit strengths that bars do not. Use them once or twice a week, not every day, so your forearm tendons can recover.
5. Keep Building Overall Strength
Grip rarely improves in isolation for long. A full-body program built around compound lifts and steady progression is what keeps total strength, and grip with it, moving in the right direction. If you are over 40, our guide to creatine for older adults covers how supplementation fits into that plan.
Can Creatine Help Grip Strength?
Creatine is one of the most-studied supplements for strength in older adults, but it is worth being precise about what the evidence shows. A 2017 meta-analysis by Chilibeck, Kaviani, Candow and Zello pooled 22 randomized trials with 721 older adults (mean ages 57–70 across studies) doing resistance training 2–3 days a week for 7–52 weeks. Compared with placebo, creatine added about 1.37 kg more lean tissue mass and produced greater gains in chest press and leg press strength. The authors reported no conflicts of interest.
Grip is a different story. Three of the included trials also measured handgrip, and none found a difference between creatine and placebo. So the honest framing is this: creatine can support the whole-body strength and lean mass gains you get from lifting,* while direct grip training is what moves your grip.

Grip Strength FAQ
What is a good grip strength for my age?
In the large British dataset, median grip peaked at about 51 kg for men and 31 kg for women in early adulthood, then gradually declined from midlife. Compare yourself with people of your own sex and age group, and focus on whether your number is holding steady or improving over time.
Is grip strength linked to longevity?
In observational research, yes. In the PURE study, each 5 kg lower grip was associated with 16% higher all-cause mortality. That makes grip a useful marker of overall strength and health, but it does not prove that grip training alone will change your lifespan.
How long does it take to improve grip strength?
Many lifters notice better holds on deadlifts and carries within a few weeks of consistent grip work, counting heavy pulls, carries and hangs across the week. Measurable dynamometer gains in older adults tend to be modest, which is why consistency over months matters more than any single program.
Does creatine increase grip strength?
Not clearly. Creatine plus resistance training increases lean mass and chest and leg press strength in older adults, but the three trials in that analysis that tested handgrip found no difference versus placebo. Use it to support overall strength, and train grip directly.
The Bottom Line
Grip strength is one of the simplest windows into your overall strength, and large studies link a weaker grip with poorer long-term outcomes. It peaks in your late 20s to 30s and slides from midlife, but it stays trainable, including in older adults. Lift heavy with your hands, carry heavy things, hang from a bar, and keep building full-body strength. Creatine can support the lean mass and strength you build in the gym,* and direct grip work takes care of your hands.
