What is a repetition (rep) in the context of exercise?

A repetition, commonly referred to as a "rep," specifically denotes one complete cycle of a particular exercise or movement. This could involve any type of physical activity where a distinct action is performed, such as lifting a weight, completing a push-up, or executing a squat. Each time you perform the movement from start to finish, you count that as a single rep.

Understanding this term is crucial for gauging workout intensity, volume, and progress. For instance, knowing how many reps are performed can help individuals track strength gains and endurance improvements over time.

The other choices do not accurately define a rep. The total time spent exercising considers duration rather than movement; the number of participants pertains to group dynamics and not individual exercise; and a series of exercises refers to a broader workout format rather than the specific action of one repetition.
