Longevity and All-Cause Mortality

A massive 2022 *British Journal of Sports Medicine* study of 370,000 adults showed that combining cardio and weights reduces all-cause mortality risk by 40%—**20% more than #1's fat loss focus alone achieves**. Grip strength emerged as a stronger longevity predictor than cardiovascular fitness in multiple cohorts, challenging the primacy of running. Each 5 kg increase in grip strength is linked to a 16% lower mortality risk, underscoring that weights are not optional for lifespan extension. The data is clear: the optimal strategy is hybrid, not adversarial.
