All . I'd say that the forward weight transfer DB refers to is a really good foundational principle to apply most of the time, but there are definitely situations where you would take a different approach.
Alright then. I couldn't place what it was in the clip that looked unorthodox since the hips were doing its job but now I know. I think I confused the don't lean part with the forward transfer. It's probably also my traditional martial arts muscle memory.
