In the context of gym workouts, "rep" is short for "repetition," which refers to a single execution of an exercise. For example, one pushup is one rep, and 10 pushups are 10 reps. A "set" is a collection of reps. In strength training, reps are the number of times you complete a single exercise before taking a rest or a break. The number of reps and sets you do, as well as the amount of weight you lift, can vary based on factors such as your fitness goals and fitness level
. The general rule of thumb is to lift lighter weights for a higher number of reps and heavier weights for a lower number of reps
