Frequently Asked Questions

Why does grip strength matter?
Grip strength predicts: all-cause mortality (Leong 2015 Lancet, 17 countries), cardiovascular mortality, fall risk in elderly, recovery from surgery, cognitive decline. Stronger predictor than BMI.
How do I measure grip without a dynamometer?
Dead hangs (time): poor < 30sec, good > 60sec, elite > 90sec. Or farmer carry: poor < 1×bodyweight, good > 1.5×, elite > 2×. Both correlate strongly with dynamometer kg readings. Best: get a Camry hand dynamometer (~€25).
How to improve grip strength?
Compound lifts (deadlift, pull-ups) hit grip indirectly. Direct work 2-3×/wk: dead hangs (15s × 4 sets), farmer carries (60m × 3 sets), thick-bar work, Captains of Crush grippers. 6 weeks → 5-10kg gain typical.
