In strength training, reps refer to the number of times you complete a single exercise before taking a rest or a break. A set is a collection of reps. For example, if you do 10 pushups, that would be 10 reps, and if you do three sets of 10 pushups, that would be 30 reps in total. Completing several reps of a specific exercise in a row is called a set. It’s a common workout strategy to do a planned number of sets of each exercise, with time built in for a short rest between these sets. Using reps and sets to organize your workouts has many benefits. They can be very useful in gauging your baseline strength and measuring your progress. Following a defined workout plan can also help take the guesswork out of strength training.
