Summary
Strength training focuses on increasing the ability to move more weight, while hypertrophy training focuses on increasing the size of muscle fibers. There is a strong relationship between strength and hypertrophy, especially for beginners and intermediate trainers. However, as training progresses, they become more disentangled. Strength and hypertrophy are not the same thing, as strength is a measure of force and function, while hypertrophy is a measure of muscle size without necessarily indicating strength. It is possible to get stronger without adding much muscle mass, as strength is influenced by factors such as neuromuscular ability, mechanics, technique, and skill. The main components of strength are physiology (neuromuscular ability and muscle fiber contractility) and mechanics (biomechanics, technique, skill).
