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.

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)

  • 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.

  1. Test one lift (squat, bench, deadlift)
  2. Compare to your age/gender benchmark
  3. Train consistently for 12 weeks
  4. Retest and compare

Ignore the person next to you. Your only competitor is yourself 3 months ago.
