Muscular endurance is best defined as a muscle's ability to contract repeatedly or sustain a continuous contraction at a level lower than maximum force. This characteristic is crucial for activities that require prolonged exertion, such as running, cycling, or swimming, where muscles must perform over extended periods without fatigue.
