The Science of Muscle Hypertrophy
Understanding how muscles actually grow at a cellular level, and how to program your workouts to maximize this process.
Muscle hypertrophy is the increase in mass and cross-sectional area of the muscle. This happens primarily through mechanical tension, metabolic stress, and muscle damage.
Mechanical Tension
This is the most important factor. Lifting heavy weights through a full range of motion creates tension on the muscle fibers.
Metabolic Stress
The "pump" you feel during high-rep sets. This also signals growth pathways.
