aerobic and anaerobic fitness

Aerobic fitness refers to the body’s ability to use oxygen efficiently during sustained physical activity, like running or cycling. It improves heart, lung, and blood vessel function, allowing longer, more intense workouts. Anaerobic fitness involves short bursts of high-intensity effort, such as sprinting or heavy lifting, where the body relies on stored energy without using oxygen. Both types of fitness are essential for overall health and athletic performance, with aerobic improving endurance and cardiovascular health, while anaerobic enhances strength, power, and muscle capacity.
