Most people have no idea if they’re strong.
You hit a personal record on deadlift and feel great. But is it actually good? Or average? Or below average for your age?
This guide gives you the actual numbers, CDC/ACSM strength standards by age and gender. So you can stop guessing.
Strength Standards (% Body Weight)
| Age/Gender | Squat | Bench | Deadlift | Overhead |
|---|---|---|---|---|
| men_20s | 1.25× | 0.85× | 1.75× | 0.65× |
| men_30s | 1.2× | 0.8× | 1.65× | 0.6× |
| men_40s | 1× | 0.7× | 1.4× | 0.5× |
| men_50s | 0.8× | 0.55× | 1.1× | 0.4× |
| men_60s | 0.6× | 0.4× | 0.8× | 0.28× |
| men_70s | 0.4× | 0.25× | 0.5× | 0.18× |
| women_20s | 0.75× | 0.4× | 1× | 0.3× |
| women_30s | 0.7× | 0.38× | 0.95× | 0.28× |
| women_40s | 0.6× | 0.33× | 0.8× | 0.23× |
| women_50s | 0.45× | 0.25× | 0.6× | 0.18× |
| women_60s | 0.35× | 0.2× | 0.45× | 0.14× |
| women_70s | 0.25× | 0.15× | 0.3× | 0.1× |
VO2 Max by Age (mL/kg/min, untrained)
Why the Difference Between Age Groups
Strength peaks around age 25-35. After 40, natural decline is ~1-2% per year if untrained. But training blunts this, a 60-year-old who lifts consistently often outlifts a 40-year-old who doesn’t.
The real message: Your age matters less than your training consistency.
VO2 Max by Age (Cardiovascular)
While we’re here: your aerobic capacity also changes with age.
- 20s: 45 mL/kg/min (peak)
- 30s: 43 mL/kg/min
- 40s: 40 mL/kg/min
- 50s: 35 mL/kg/min
- 60s: 28 mL/kg/min
- 70s: 20 mL/kg/min
Untrained. If you run 3x/week, add ~20-30% to these numbers. Elite endurance athletes can hit 70+ mL/kg/min at any age.
Flexibility Standards (Sit & Reach, inches)
| Age Group | VO2 Max (mL/kg/min) | Flexibility - Sit & Reach (inches) |
|---|---|---|
| 20s | 45 (peak) | 95th: 11", Avg: 9", 5th: 2" |
| 30s | 43 | - |
| 40s | 40 | 95th: 10", Avg: 7", 5th: 0" |
| 50s | 35 | - |
| 60s | 28 | 95th: 8", Avg: 4.5", 5th: -2" |
| 70s | 20 | - |
- 20s: 95th percentile = 11", average = 9", 5th percentile = 2"
- 40s: 95th = 10", average = 7", 5th = 0"
- 60s: 95th = 8", average = 4.5", 5th = -2"
Most people lose flexibility with age. Stretching 3x/week stops (or reverses) this.
How to Use This
Track yourself, not others.
- Test one lift (squat, bench, deadlift)
- Compare to your age/gender benchmark
- Train consistently for 12 weeks
- Retest and compare
Ignore the person next to you. Your only competitor is yourself 3 months ago.
