A set of definitions exists in the Senate ESEA bill written and voted out of the HELP Committee (Health, Education, Labor and Pensions).
Reps and sets are terms used by exercise professionals, athletes and individuals in the gym. They provide structure and organization to your workout. If you work with a personal trainer or physical therapist, she will prescribe an exercise based on a specific number of sets and reps.
Best Answer: Rep means repetitions. Doing a set of 20 reps of pushups means doing 20 pushups. As to how many reps you should do, I suggest that you start with 10 and slowly build up to your limit. A rep is a repetition. You do a rep each time you do the complete motion the exercise entails. It is just a fancy way of saying how many times you did it. If I was doing pushups and I said I did 70 reps, that just means I did 70 pushups.
