How does your fitness compare to people your age?

ExRx publishes the most widely-referenced strength standards for the bench press, broken into five training categories: untrained, novice, intermediate, advanced, and elite. For a 175 lb male, intermediate is roughly 215 lb (about 1.2x bodyweight), advanced is 290 lb (1.65x), and elite is 360 lb (about 2x). For a 140 lb female at the same training level, intermediate is around 110 lb (0.79x bodyweight), advanced is 155 lb (1.1x), and elite is 200 lb (1.4x). The standards are deliberately based on natural (untested for performance-enhancing drug use) lifters with at least a few months of consistent training. Where you sit also depends heavily on age: a 30-year-old at intermediate is broadly comparable to a 50-year-old at advanced, because raw strength peaks in the late 20s and declines around 1 percent per year after 35, accelerating slightly after 60. Bodyweight matters too: a 220 lb intermediate is benching meaningfully more than a 165 lb intermediate even at the same training age, because absolute strength scales with cross-sectional muscle area. The bench press strength calculator returns your exact ExRx category and percentile against your age and sex.

Strava's 2024 global insights data put the median 5k time at around 32 minutes for men and 36 minutes for women across all logged activities, but that includes a long tail of run-walk efforts and recreational logging. Among runners actively training for the distance and submitting parkrun results, the median sits closer to 27 minutes for men and 30 minutes for women, with significant age and sex stratification. A sub-25 minute 5k puts a male runner in roughly the 70th percentile of trained runners; a sub-22 puts you in the top 10 percent; a sub-19 puts you in the top 2 percent. For women the equivalent thresholds are roughly sub-28, sub-25, and sub-22. Cooper Institute's age-adjusted norms tighten this further: a 50-year-old running 25 minutes is in a different percentile band than a 30-year-old running the same time, and the World Masters Athletics age grading tables adjust further still. The running pace percentile tool uses Strava aggregate data with Cooper-style age and sex adjustments and returns your exact position on the curve, with parkrun finish-time context as a sanity check.

Across the ten largest marathons in 2024 (New York, Chicago, Boston, London, Berlin, Tokyo, Paris, Sydney, Amsterdam, and Valencia), the median finish was 4 hours 21 minutes for men and 4 hours 48 minutes for women. The traditional shorthand is that a sub-4 hour marathon puts a man in roughly the top 30 percent of finishers; sub-3:30 is top 15 percent; sub-3 is top 5 percent of the global marathon-running population. For women the equivalents are sub-4:30, sub-4, and sub-3:30. Boston Qualifying times function as a stricter cut: about 8 percent of men under 35 hit the BQ standard of 3:00 in any given year, with the time cut widening for older age groups (a 65-year-old man's BQ is 4:05). The current world records, set on the Berlin and Chicago courses, sit at 2:00:35 for men (Kelvin Kiptum, 2023) and 2:09:56 for women (Ruth Chepngetich, 2024), which compresses the elite end of the curve dramatically. The marathon pace calculator returns your projected finish based on training paces, applies Riegel's race-time prediction formula, and shows where it sits in current percentile data with age-grading included.

The most validated approach is the NTNU Fitness Age model from the Norwegian University of Science and Technology, which estimates VO2 max from resting heart rate, waist circumference, exercise frequency, height, weight, and age, then maps that estimated VO2 max against the population reference for each age band. If your VO2 max sits two standard deviations above the median for your chronological age, your fitness age is roughly 10 to 15 years younger; two standard deviations below, and it is 10 to 15 years older. The model has been validated against directly-measured VO2 max in over 5,000 participants from the HUNT3 cohort study, with a published correlation around r=0.75 against treadmill-measured values. The Cooper Institute's fitness norms provide a complementary cross-check using six-minute walk distance and field-test data. The fitness age calculator on Find The Norm uses the NTNU non-exercise estimation formula, returns both your estimated VO2 max and your fitness age, and shows the population percentile you sit in for your chronological age band, with an honest confidence range rather than a single number.

VO2 max is the volume of oxygen (in millilitres per kilogram of bodyweight per minute) that your cardiovascular system can deliver to working muscle at peak exercise, and it is the single strongest predictor of all-cause mortality in middle and older age. A 2018 JAMA study of over 122,000 patients found that low cardiorespiratory fitness was associated with a higher mortality risk than smoking, diabetes, or hypertension. The ACSM and Cooper Institute reference tables give age-adjusted population norms: for a 30-year-old male, around 42 ml/kg/min is average and above 53 is excellent; for a 30-year-old female, around 35 is average and above 45 is excellent. A 60-year-old male over 35 ml/kg/min sits in the excellent band for that age, even though the same number would be average for a 30-year-old. Elite endurance athletes range from 70 to over 80, with cross-country skiers, cyclists, and rowers occupying the top tier (Bjorn Daehlie's measured 96 remains one of the highest ever recorded). The fitness age tool returns your estimated VO2 max alongside age-adjusted percentile.

Less than most people assume. The CDC's 2022 NHIS data found that only 23 percent of Americans meet both the cardio guideline (150 minutes of moderate or 75 minutes of vigorous exercise per week) and the strength guideline (two or more sessions targeting all major muscle groups). Roughly 47 percent meet the cardio guideline alone, and around 28 percent meet the strength guideline alone. Around 25 percent of US adults report no leisure-time physical activity at all in a typical week. That means if you complete a single 30-minute run three times a week, you are already above the median American for cardiovascular activity. Adding two short strength sessions, even bodyweight only, puts you firmly in the top quarter on the combined measure that the CDC tracks. The framing matters: most people overestimate how much exercise the average adult does because their reference point is their gym-going friends or their social media feed, not the population the CDC actually surveys. The is-35,000-steps-too-much tool maps step counts against population data, and the sports performance benchmarks hub links to all the strength and endurance comparison tools.

Find The Norm draws from a small set of established reference sources for fitness data. Strength standards come from ExRx.net, which has aggregated lifter data since the late 1990s and remains the most-cited reference among strength coaches for natural lifter benchmarks across the bench press, squat, deadlift, and overhead press. Cardiorespiratory norms use the American College of Sports Medicine's published reference tables (currently in the 11th edition of the ACSM Guidelines) alongside the Cooper Institute's age and sex-adjusted percentiles built from the Aerobics Center Longitudinal Study. Running pace data comes from Strava's annual global insights report, which aggregates anonymised activity from over 100 million users worldwide and is the largest publicly-cited running dataset. Marathon finish-time data uses official race results from the World Marathon Majors. VO2 max estimation uses the NTNU non-exercise prediction formula validated in HUNT3. CDC NHIS data anchors the activity-prevalence framing. Each tool cites its specific sources on the page and notes the date the underlying numbers were last verified, so you can judge the freshness yourself.
