Strength assessment includes grip strength, measurable with a hand grip dynamometer (aiming for 40kg+ for men, 35kg+ for women, with <10% asymmetry), and dead hangs (minimum 30 seconds). For lower body strength, a leg extension test using bodyweight is a key benchmark for individuals under 40, with targets decreasing slightly with age. Alternatively, a goblet squat hold with half bodyweight for 45 seconds assesses core and lower body stability.

Impact: High. Evaluating strength through grip, dead hangs, and lower body tests provides critical insights into overall physical capacity and potential injury risks. These metrics are vital for building a balanced physique and ensuring functional independence across the lifespan.
