Swimming is a low-impact, full-body cardiovascular and resistance exercise that improves cardiorespiratory fitness, muscular endurance, and body composition without stressing joints. Its healthspan benefits stem from enhancing mitochondrial function, reducing systemic inflammation, improving insulin sensitivity, and promoting neurogenesis, directly countering several hallmarks of aging.
Verdict
A top-tier, sustainable exercise for lifelong health and mobility.
