Grip Rating

Grip strength is measured with a hand dynamometer — squeeze as hard as possible for 3 seconds with the elbow at 90°. Reference values are derived from normative data tables (Mathiowetz et al. and Dodds et al.) which are widely used in clinical and sports settings. Non-dominant hand grip is typically 5–10% weaker than the dominant hand.

Grip Strength as a Health Biomarker

Grip strength has emerged as one of the most powerful predictors of overall health and longevity. A landmark 2015 Lancet study of 140,000 participants across 17 countries found that every 5 kg decrease in grip strength was associated with a 17% higher risk of cardiovascular mortality, 9% higher all-cause mortality, and 9% higher risk of stroke. Grip strength reflects total body muscle mass, neural activation capacity, and the overall state of the musculoskeletal system. It is now routinely used in clinical settings as a frailty screening tool, particularly in older adults. In sports, grip is also critical for weightlifting, climbing, racquet sports, martial arts, and gymnastics.

Frequently Asked Questions

For men aged 20–39, average dominant hand grip is 46–52 kg (101–115 lbs). Excellent is above 58–60 kg (128–132 lbs). Below average (possible health concern in older adults) is under 36 kg. Grip peaks in the late 30s–40s and declines with age. Trained athletes typically score 55–75 kg depending on sport and body size.
Grip strength is a proxy for total body muscle mass and neuromuscular function. Large cohort studies show: 5 kg lower grip → 17% higher cardiovascular mortality (Lancet 2015). Low grip is associated with sarcopenia, frailty, falls in elderly, longer hospitalisation, and lower quality of life. In clinical geriatric medicine, grip below 27 kg (men) or 16 kg (women) indicates probable sarcopenia per EWGSOP2 criteria.
A calibrated dynamometer ($30–80) is the only accurate method. Improvised tests: squeeze a bathroom scale between both hands for a rough bilateral estimate. Dead hang time (hanging from a bar) is a functional measure: beginners <30 s, intermediate 30–90 s, strong 90–120 s, elite 2+ minutes. Crush gripper resistance ratings (Captains of Crush) provide relative strength measures but not absolute force values.
Best methods: (1) Dead hangs — 3–5 sets of max time, 2–3×/week. (2) Farmer carries — 2–4 sets of 30–60 m with 60–80% BW in each hand. (3) Thick bar training or Fat Gripz on all pulling movements. (4) Barbell holds — load above your deadlift 1RM and hold for 10 s. (5) Captains of Crush grippers — 3 sets of 10–20 reps, progressive models. Results show in 4–8 weeks of dedicated training.
