You can answer this question today with a few simple tests and a set of population-wide benchmarks. Grip strength, push-up count, and how much you can lift relative to your body weight all place you on a spectrum from beginner to elite. The specific numbers that define each level depend on your age and sex, but the tests themselves are straightforward enough to do at home or in any gym.
Two Ways to Measure Strength
Strength comparisons only make sense when you specify what kind you’re talking about. A 220-pound person who squats 400 pounds is producing more total force (absolute strength) than a 160-pound person who squats 320. But the lighter person is squatting twice their body weight, while the heavier person is squatting 1.8 times theirs. That ratio, weight lifted divided by body weight, is your relative strength, and it’s the more useful number for most purposes.
Relative strength matters more for anything involving moving your own body: running, jumping, climbing stairs, playing sports. Two people with identical leg power won’t perform identically if one weighs significantly more. The heavier person needs to generate more force just to cover the same distance and absorbs greater impact on every landing. Unless you compete in a sport where moving an external object is the whole point (like football linework or sumo wrestling), relative strength is the number to track.
Grip Strength: The Simplest Test
Grip strength is one of the most studied markers of overall muscular fitness. You can measure it with a handheld dynamometer, which many gyms, physical therapy offices, and even pharmacies carry. Squeeze as hard as you can, and you get a reading in kilograms. Here are the averages from a large population-based study, measured on the dominant (right) hand:
Men:
- Ages 20–29: 47 kg
- Ages 30–39: 47 kg
- Ages 40–49: 47 kg
- Ages 50–59: 45 kg
- Ages 60–69: 40 kg
- Ages 70+: 33 kg
Women:
- Ages 20–29: 30 kg
- Ages 30–39: 31 kg
- Ages 40–49: 29 kg
- Ages 50–59: 28 kg
- Ages 60–69: 24 kg
- Ages 70+: 20 kg
If you’re near or above these numbers for your age group, your grip strength is in the normal range. Falling well below them is worth paying attention to, because grip strength predicts more than hand function. A 28-country study of older adults found that people at the 90th percentile of grip strength (around 35 kg for men, 23 kg for women) had roughly 25% lower mortality risk compared to the median. Those at the 10th percentile (15 kg for men, 10 kg for women) had about 20–33% higher mortality risk. The relationship is gradual rather than a cliff edge: every bit of strength you gain moves the needle.
European clinical guidelines flag grip strength below 27 kg for men and below 16 kg for women as a sign of possible sarcopenia, the medical term for significant age-related muscle loss. If you’re in that range, resistance training can help reverse it at any age.
Push-Ups: A Quick Bodyweight Benchmark
The push-up is the most accessible strength test that exists. No equipment, no gym, no calculations. Here’s how many full standard push-ups rank at each level for adults in their 20s:
Men (ages 20–29):
- Excellent: 36 or more
- Very good: 29–35
- Good: 22–28
- Fair: 17–21
- Poor: 16 or fewer
Women (ages 20–29):
- Excellent: 30 or more
- Very good: 21–29
- Good: 15–20
- Fair: 10–14
- Poor: 9 or fewer
These numbers shift downward with age, so a 45-year-old “good” won’t match a 25-year-old “good.” What matters is where you fall within your age group. One study of college-aged women found the average was just 9 standard push-ups, which landed in the “good” category for that specific sample. If you can do more than that, you’re already ahead of most people your age.
Barbell Lifts: Squat, Bench, Deadlift
If you train with weights, the three powerlifts give you the most precise picture of your total-body strength. A massive dataset of over 800,000 competition entries provides percentile-based standards expressed as multiples of body weight. For adults aged 18–35, here’s what the 90th percentile (top 10% of competitive lifters) looks like:
- Squat: 2.83x body weight (men), 2.26x (women)
- Bench press: 1.95x body weight (men), 1.35x (women)
- Deadlift: 3.25x body weight (men), 2.66x (women)
These are elite numbers from people who compete in powerlifting, so they represent the high end of the spectrum. A more useful way to think about it: if you’re a man who can squat 1.5x your body weight, bench press 1.0x, and deadlift 2.0x, you’re solidly strong by general fitness standards. For women, squatting 1.0x body weight, benching 0.6x, and deadlifting 1.5x puts you in a similar spot.
Even adults over 80 showed measurable relative strength in competition data. Men in that age group at the 90th percentile squatted 1.72x body weight, and women squatted 1.01x. Strength declines with age, but it never has to disappear.
How to Estimate Your Max Without Maxing Out
You don’t need to load a bar to the absolute heaviest weight you can lift to know your one-rep max. If you can do multiple reps at a lighter weight, a simple formula gives you a reliable estimate. The most commonly used version works like this: multiply the weight you lifted by 0.033, multiply that by the number of reps you completed, and add the original weight back on.
For example, if you bench press 135 pounds for 8 reps: 135 × 0.033 = 4.46, multiplied by 8 = 35.6, plus 135 = about 171 pounds estimated max. This formula (known as the Epley equation) is most accurate in the 2–10 rep range. Beyond 10 reps, estimates become less reliable because muscular endurance starts to play a bigger role than pure strength.
What Actually Determines Your Strength
Strength isn’t just about muscle size. Your nervous system plays an equally important role by controlling how many muscle fibers activate during a contraction and how rapidly they fire. Your brain recruits motor units (bundles of muscle fibers controlled by a single nerve) in a fixed order, starting with the smallest and weakest. As you push harder, progressively larger motor units switch on, adding force in layers.
At low effort, only slow, fatigue-resistant fibers are working. As you approach maximal effort, fast, powerful fibers join in. The firing rate also matters: when a nerve sends signals faster than a muscle fiber can fully relax between contractions, the forces overlap and stack. At the highest firing rates, the muscle enters a state of sustained maximum contraction with no gaps between pulses. This is why someone can get dramatically stronger in their first few months of training without gaining visible muscle. Their nervous system is learning to recruit more fibers, faster.
Beyond the nervous system, the cross-sectional area of your muscles (how thick they are, not how long) directly determines how much force they can produce. Genetics influence your ratio of fast-twitch to slow-twitch fibers, your limb lengths (which affect leverage), and your hormonal profile. But training is the single biggest modifiable factor. Even among the oldest adults studied, muscle strength responded to resistance training, and every increment of improvement carried measurable health benefits.
Putting Your Numbers in Context
Wherever you fall on these scales, context matters. Someone who just started training three months ago and squats 1.0x body weight is on a completely different trajectory than someone who’s been training for ten years and squats the same. Strength builds quickly in beginners (gains of 20–30% in the first few months are common) and slows as you get more advanced.
The most practical takeaway from all of these benchmarks is that being “strong enough” isn’t a single number. A grip strength above 27 kg (men) or 16 kg (women) keeps you above the clinical threshold for muscle loss. Being able to do 15+ push-ups puts you in the “good” range for most age groups. Squatting and deadlifting your own body weight means your legs and back can handle the demands of everyday life with room to spare. If you’re hitting those marks, you’re stronger than most of the general population, even if you never touch a competition platform.
