1. Sets: A set refers to a group of consecutive repetitions of a particular exercise. For example, if you perform 10 squats in a row, that would be considered one set of squats.
2. Repetitions (Reps): Repetitions, often abbreviated as "reps," represent the number of times you perform a specific movement within one set. Continuing with the squat example, each individual squat performed within the set is a single repetition. So, if you do 10 squats without taking a break, that would be 10 reps in one set.
For example, a workout routine might specify "3 sets of 12 reps" for squats. In this case, you would perform 12 repetitions of squats, take a rest, and then repeat the exercise for two more sets, each with 12 reps.
The number of sets and reps you use in your workout can vary depending on your fitness goals.
