Reps, short for repetitions, refer to the number of times you complete a single movement of an exercise before taking a rest. For example, performing one full push-up or one bicep curl counts as one rep. When you do several reps consecutively, that group is called a set. So, in strength training or resistance training:

• One rep = one complete movement of an exercise (like one push-up, one squat, or one curl).
• One set = a group of consecutive reps done without resting.

For example, if you do 12 push-ups in a row, that's one set of 12 reps. After resting, doing another 12 push-ups would be a second set of 12 reps. Reps are a fundamental way to structure and track your workouts depending on your fitness goals, whether for strength, muscle growth, or endurance. Different rep ranges emphasize different outcomes:

• Low reps (1-6) for maximum strength and power.
• Moderate reps (6-12) for muscle growth.
• High reps (12 or more) for muscular endurance.

This helps you plan how many times to repeat an exercise in a workout session for optimal results.
