What is a set? what is a repetition? how do sets and repetitions relate to one another in the context of a workout?

A set is a group of repetitions. Sets and repetitions are common in strength-building exercises. For example, you might do one set of 10 push-ups: there are 10 repetitions in the set. If you do a second set of push-ups, you will have done 20 push-ups in all. In this case, two sets represent 20 repetitions.
