Hi Dr Darden,
Recently saw a 2020 scientific review on studies re stretching for hypertrophy. In short, it seems that stretching in between, or in direct correlation with sets/excercise can provide a positive effect. I heard a similar opinion during a seminar with a semi-pro bodybuilder in 1993.
Stretching afterwards doesn’t have any effect appearantly, which is bad news for me. I do it routinely since many years for stress relief after a workout.
What are your take on this? Any good experience? How did the old school bodybuilders do?
