What do the 'sets' refer to in weight training?

In weight training, 'sets' refer to a specific number of repetitions performed continuously without resting. When an athlete completes a designated number of repetitions of a particular exercise, that group of repetitions is considered one set. For instance, if a person performs ten bicep curls in sequence before taking a rest, they have completed one set of ten repetitions. Sets are a fundamental component of strength training programs as they help structure workouts, targeting specific muscle groups and contributing to overall strength and endurance development.

Understanding sets allows individuals to effectively manage their workout intensity and volume, ensuring they can progressively increase the load over time for optimal gains in muscle strength and size.
