Grip strength, easily tested by squeezing a tennis ball, is a surprisingly strong indicator of overall health and longevity. Studies show a strong correlation between grip strength and lifespan, with those having stronger grips more likely to live past 100. Weak grip strength can signal risks like sarcopenia, type 2 diabetes, and even accelerated aging. Improving grip strength is possible through regular physical activity, resistance exercises, and targeted hand exercises.
