New research confirms what evidence-based coaches have known for years — muscle mass is the strongest predictor of how well you age.
Muscle isn't just about strength or aesthetics. It's a metabolically active organ that plays a critical role in insulin sensitivity, metabolic health, and resilience against disease. The more muscle you carry into your later decades, the better your body handles the physical and metabolic challenges of ageing.
Building and maintaining muscle through resistance training is one of the most powerful interventions you can make for your healthspan. It's never too early to start, and never too late to benefit.
