An expert discussion featured in Medical News Today’s “In Conversation” podcast highlights the crucial role of exercise in promoting longevity and reducing the risk of disease. Studies consistently show that simple lifestyle changes—particularly physical activity—can extend both lifespan and health span. A major study found that a mix of moderate aerobic exercise, vigorous activity, and muscle-strengthening exercises offered the most significant protection. For example, combining 150 to 225 minutes of moderate activity, 75 minutes of vigorous activity, and at least two strength sessions per week reduced risks of death from all causes, especially cardiovascular disease.

Even smaller amounts of vigorous exercise may offer meaningful benefits. One study found that just 2 minutes of high-intensity activity daily could cut death risk from cancer or heart events. Importantly, both experts emphasized that any physical activity is better than none, but leisure-time exercise is more beneficial than physically demanding jobs, which may increase health risks due to stress and overexertion. They also noted that individualized guidance from healthcare professionals is key, especially for older adults or those with existing health concerns. Overall, intentional, balanced physical activity emerges as a powerful, accessible tool to support long and healthy lives.
