What does the term "muscular endurance" refer to?

Muscular endurance refers to the ability of a muscle or group of muscles to sustain repeated contractions against a resistance for an extended period of time. This is essential in various physical activities where prolonged effort is required, such as running, cycling, or performing multiple repetitions of an exercise like push-ups. The focus is on how well muscles can perform continuously over a duration rather than how much weight they can lift at one time.

This concept is crucial for fitness instructors to understand, as it influences the design of training programs that aim to improve clients' performance in endurance-related activities. Many clients may benefit from developing this type of endurance to enhance their overall fitness or to meet specific athletic goals.
