@thegravgear: Peter Attia's floor for functional grip: - Men in their 40s — 2 minutes - Women in their 40s — 90 seconds Most people are nowhere close. The Lancet tracked 140,000 adults for four years. Every 5kg drop in grip strength came with a 16% higher risk of death. But grip isn't the cause. When your grip goes, your whole body is already going with it. Grip is just the easy part to measure. Where to start: arms straight, shoulders relaxed, feet off the floor. 30 seconds, three times a week. Doorframe bar, before your shower.
