Which of the following describes muscular endurance?

Muscular endurance is defined as the ability of a muscle or group of muscles to sustain repeated contractions against a resistance or continue to exert force over an extended period of time without experiencing fatigue. This means that an individual with high muscular endurance can perform a particular exercise or series of exercises multiple times before feeling tired or needing to rest.

This understanding differentiates muscular endurance from other concepts such as muscular strength, which refers to the maximum force a muscle can produce, and flexibility, which relates to the range of motion in joints. Additionally, cardiovascular health pertains to the efficiency of the heart and lungs in supplying oxygen to the body during physical activity, which is not directly related to the endurance of individual muscles. Thus, the emphasis of muscular endurance is solely on the sustained capacity of muscles during repetitive, lower-intensity activities.
