Training for sarcoplasmic hypertrophy is characterized by lower resistances and a larger number of repetitions. This training style focuses on increasing the volume of endurance-based workouts rather than the sheer strength that comes from lifting heavy weights.

Sarcoplasmic hypertrophy enhances the muscle's ability to store energy, specifically in the form of glycogen, which fuels muscular endurance. By using lower weights with higher repetitions, the muscles undergo metabolic stress and adaptations that lead to an increase in the sarcoplasmic fluid surrounding the muscle fibers. This approach aims to improve muscular endurance, stamina, and overall performance in activities where sustained effort is required.

Conversely, training methods that emphasize higher resistances and lower repetitions typically contribute to myofibrillar hypertrophy, which is focused on increasing muscle fiber size and strength rather than enhancing endurance capabilities. Therefore, the focus on lower weights and higher repetitions distinctly highlights the training goals associated with sarcoplasmic hypertrophy.
