How much strength do you lose with age?

By Stelvo Team · · 5 min read · How we source this

Short answer: less than you'd fear until your 50s, then faster. Among raw powerlifting competitors since 2020, bodyweight-adjusted strength holds through the 30s, then is about 6% lower in the 40s, 14% lower in the 50s, 24% lower in the 60s and 37% lower past 70 (men, against their peak in the 30s). Women follow almost the same curve: 9%, 16%, 26% and 36% below their peak in the 20s. After 40 the loss runs at roughly 8–12% a decade and speeds up after 60. Population studies of grip strength show the same shape, peaking around 30–40 and falling from midlife — and training slows it at any age.

When does strength peak?

In your 30s for men, your 20s and 30s for women. In our analysis of meet results, men's bodyweight-adjusted strength was highest at 30–39 (median Dots 375.6, median total 1,290 lb), and women's was highest at 18–29 with the 30s close behind (Dots 335.6 and 324.3; median total 711 lb in both bands). A study that pooled 49,964 people from twelve British population studies found the same window for grip strength: men's median grip peaked at 51 kg between ages 29 and 39, women's at 31 kg between 26 and 42, followed by maintenance through midlife and decline after it (Dodds et al., PLoS One, 2014).

How much strength do you lose per decade?

Here is the full picture. We computed it from the OpenPowerlifting archive (bulk data, public domain, snapshot of 19 September 2026): raw, sanctioned, non-disqualified full-power meets since 2020, and each lifter's best result within each age band they competed in. Because older lifters tend to weigh differently, the change column uses Dots — a bodyweight-adjusted score that OpenPowerlifting describes as similar to, and drop-in compatible with, the Wilks formula (OpenPowerlifting column documentation).

Age Men: median total Men: vs peak Women: median total Women: vs peak
18–29 1,235 lb −0.5% 711 lb peak
30–39 1,290 lb peak 711 lb −3.4%
40–49 1,218 lb −6.2% 672 lb −9.1%
50–59 1,102 lb −14.3% 606 lb −16.2%
60–69 959 lb −23.6% 529 lb −26.1%
70+ 755 lb −37.5% 449 lb −36.2%

"vs peak" compares median Dots. Men n = 96,119, 29,642, 10,645, 5,185, 2,586 and 945 by band; women n = 40,264, 18,712, 8,558, 3,648, 1,448 and 362.

Decade to decade, men lose 8.6% of their bodyweight-adjusted strength from their 40s to their 50s, 10.9% from their 50s to their 60s and 18.2% from their 60s to their 70s; women lose 7.8%, 11.8% and 13.7%. The curve steepens with every decade.

Why does strength fall with age?

Mostly because muscle does. Muscle mass decreases by approximately 3–8% per decade after the age of 30, and the rate is higher after 60 (Volpi et al., Current Opinion in Clinical Nutrition and Metabolic Care, 2004) — the same acceleration the meet data shows. An analysis of US age-group powerlifting and weightlifting records found performance declining "progressively even from earlier ages than previously thought", with the bench press and the squat falling at similar rates and no difference between men and women in powerlifting (Anton, Spirduso & Tanaka, Medicine & Science in Sports & Exercise, 2004). Our numbers match on the last point too: the men's and women's curves are within a few points of each other at every age.

Does everyone lose strength at the same rate?

No, and these numbers are a best case. They are cross-sectional — different people in each age band, not the same people followed for decades — and a 65-year-old who still competes is someone who kept training. In the general population the loss is steeper: in the British grip-strength data, weak grip (2.5 standard deviations below the peak) reached a prevalence of 23% in men and 27% in women by age 80 (Dodds et al., 2014). Read the table as what the decline looks like for people who keep lifting.

Can you slow strength loss with age?

Yes, and it is never too late to start. Frail nursing-home residents aged 90 who did eight weeks of high-intensity resistance training gained an average of 174% in strength and 48% in walking speed (Fiatarone et al., JAMA, 1990). The muscle side of the story — how much you lose and how much comes back — is in how much muscle do you lose as you age?, and the strength percentile calculator shows where your own lifts rank against every competitor in your weight class.

How Stelvo handles this

Stelvo takes your age, sex and training history into account when it sets starting weights, and progresses them in small, logged steps. Tell the coach about a shoulder or knee that complains and it remembers, and plans around it.

FAQ

At what age do you start losing strength?

In competitive lifters, bodyweight-adjusted strength starts to fall in the 40s, about 6% below the peak for men and 9% for women. In the general population, grip strength declines from midlife onwards.

How much weaker is a 60-year-old than a 30-year-old?

Among raw powerlifters, about 24% weaker for men once bodyweight is accounted for; for women, about 26% below their peak in the 20s. People who don't train lose more.

Can you gain strength after 60?

Yes. Strength responds to training at every age measured, including 90-year-olds, who gained 174% in eight weeks in a controlled trial.
