In physical fitness, what is the number of repetitions done in succession referred to?

In the context of physical fitness, the term used to describe the number of repetitions performed in succession is known as a "set." A set comprises a specific number of consecutive repetitions of an exercise without rest. For example, if an individual performs 10 push-ups in a row, that is considered one set of 10 repetitions. Understanding this distinction is crucial in fitness training, as sets and repetitions are fundamental concepts used to structure workouts, monitor progress, and achieve different fitness goals.

While "rep" refers specifically to a single repetition of an exercise, it is the combination of multiple repetitions into a set that effectively contributes to muscle engagement and endurance. The other terms like "sequence" and "cycle" do not specifically denote the concept of repetitions in exercise, making “set” the most accurate answer in this context.
