The Fitness Sweet Spot
By Editorial Staff
For years, fitness advice has been split into camps: cardio for heart health, weights for strength, and endless debate about which matters more. But a large-scale research study published in the
British Journal of Sports Medicine points to a simple answer – it isn't an either-or choice at all.
The biggest long-term health gains come from combining aerobic and resistance exercise, with the two working together to reduce the risk of early death more effectively than either one alone.
Importantly, more is not always better. The research suggests diminishing returns at very high training volumes, particularly for resistance exercise. The goal is not extremes, but consistency.
The "Sweet Spot" for Maximum Benefit
But there's more: A key message from the study is not just that both matter; there appears to be a practical "sweet spot" at which the combination delivers the strongest overall benefit.
- Resistance training: approximately 90-120 minutes per week
- Aerobic activity: up to approximately 45 MET hours per week
Why the Combination Works
Aerobic exercise improves cardiovascular efficiency, while resistance training preserves muscle mass, strength, and metabolic health. Together, these systems support each other over time.
Together, they address multiple aging pathways at once, including cardiovascular decline, muscle loss, and metabolic dysfunction.
