How to Measure Grip Strength

Best Method: Hand Dynamometer

Digital hand dynamometers are available for ~$30 on Amazon. It's one of the most cost-effective health investments.

Alternative: Gym or Clinic

Many gyms, physical therapists, and doctors have dynamometers. Ask during your next visit.

Elite Benchmark: Kayla Barnes-Lentz

At age 35, Kayla achieved 98.9 lbs (44.9 kg) grip strength— placing her in the 99th percentile for females. This correlates with her exceptional longevity biomarkers.

Research & Methodology

Key Research

  • Leong et al., Lancet 2015: Grip strength was a stronger predictor of all-cause and cardiovascular mortality than systolic blood pressure in a study of 140,000 people across 17 countries.
  • NHANES Data: Percentile calculations based on National Health and Nutrition Examination Survey normative data for US population.

How to Improve

  • Dead Hangs: 3 sets to failure, 2-3x per week
  • Farmer Carries: 50% bodyweight per hand, 1 minute
  • Pull-ups & Rows: Compound pulling movements
  • Dedicated Grip Training: Grippers, pinch holds, wrist curls
