Muscular endurance refers to the capacity of a muscle or muscles to continue working through the repetition of movements or to sustain a contraction for an extended duration. It indicates the duration for which your muscles are able to continue working before tiring.
In sports that require a lot of energy, such as running, cycling, rowing, and swimming, powerful muscles enable athletes to perform for hours without ever tiring. Training often involves performing numerous exercises using light weights, such as bodyweight exercises or sport-specific drills (such as quick cycling classes or swimming laps). Possessing more mitochondria, more blood vessels, and muscles that don’t tire easily are what enhance muscle endurance, enabling muscles to generate energy and eliminate waste during prolonged activities.
