Low Reps = DENSE Muscles, High Reps = PUFFY Muscles
House of Hypertrophy・2 minutes read
Different rep ranges can lead to various types of muscle fiber growth, with higher reps potentially causing sarcoplasmic hypertrophy, while classic bodybuilding ranges do not necessarily preferentially produce this type of growth. Powerlifters tend to experience myofibular hypertrophy, while bodybuilders may undergo sarcoplasmic hypertrophy.
Insights
- Different rep ranges can lead to distinct types of muscle fiber growth, influencing muscle appearance and function.
- Powerlifters tend to experience myofibril hypertrophy, while bodybuilders may undergo sarcoplasmic hypertrophy, showcasing diverse adaptations based on training styles.

Recent questions
How do different rep ranges affect muscle hypertrophy?
Different rep ranges can impact muscle hypertrophy by influencing the type of muscle fiber growth experienced. Rep numbers ranging from 6 to 35, performed close to failure per set, have been shown to be effective for muscle hypertrophy. Higher reps may potentially lead to sarcoplasmic hypertrophy, while lower reps may result in myofibrillar hypertrophy or myofibrillar packing. Myofibrillar hypertrophy involves significant myofibril growth, which is important for strength and muscle density.
What is the difference between myofibrillar hypertrophy and sarcoplasmic hypertrophy?
Myofibrillar hypertrophy and sarcoplasmic hypertrophy are two types of muscle fiber growth. Myofibrillar hypertrophy involves the growth of myofibrils, which are responsible for muscle contraction and strength. On the other hand, sarcoplasmic hypertrophy refers to the growth of the sarcoplasm, the fluid and energy stores within muscle fibers. Myofibrillar hypertrophy is associated with increased muscle density and strength, while sarcoplasmic hypertrophy may lead to a fuller or puffier muscle appearance.
What type of muscle fiber growth do bodybuilders and powerlifters typically experience?
Bodybuilders may experience sarcoplasmic hypertrophy, which can contribute to a fuller muscle appearance, while powerlifters or weightlifters often experience myofibrillar hypertrophy. Myofibrillar hypertrophy involves significant growth of myofibrils, leading to increased muscle density and strength. The type of muscle fiber growth experienced can be influenced by training methods, such as rep ranges and volume, with higher reps potentially leading to sarcoplasmic hypertrophy.
How does training volume impact muscle hypertrophy?
Training volume, or the amount of work performed in a training session, can influence muscle hypertrophy. Higher volumes of training may drive sarcoplasmic hypertrophy, but the relative expansion of sarcoplasm in muscle fibers may not significantly impact muscle appearance. Long-term studies suggest that classic bodybuilding rep ranges (7-12 reps) do not preferentially produce sarcoplasmic hypertrophy, indicating that other factors such as volume play a role in muscle growth.
