What does the rest-pause training technique primarily focus on?

The rest-pause training technique primarily focuses on extending the set by incorporating brief rest periods before continuing the repetition of the exercise. This method allows individuals to push beyond their usual limits by taking short breaks to recover enough strength to complete additional repetitions within the same set. By using this technique, a lifter can effectively increase the intensity of their training and enhance muscular endurance and strength by maximizing the time under tension, without the need for a full recovery. It specifically emphasizes the ability to perform more work in a focused and controlled manner, leveraging the brief rest to gather energy for continued effort. This approach contrasts with other training styles, as it uniquely combines elements of rest with intensity, enabling progression and adaptation in strength training.
