Hypertrophy is the growth of muscles, and it can be induced by various stimuli. Hypertrophy training is "idiot proof" in terms of programming, and there are many styles of training that all work. The adaptations of specificity drive changes in strength and power, while hypertrophy is much more well-rounded. Muscle isolation is not a natural phenomenon, and it's the nerve to muscle connections and the distinction between isolating nerve to muscle connections versus distributing the work of nerve to muscle connections that's vital in determining whether or not you generate hypertrophy isolated nerve to muscle contractions versus strength and offsetting strength loss which would be distributed nerve to muscle connections.
