A new research suggests you can induce regional hypertrophy by activating the muscle differently along a certain length. That would mean more hypertrophy that is specific to that muscle activation.

A good take home point from this is that different exercises which target a muscle from various angles, can be helpful when aiming for maximal hypertrophy.
