ive heard some guys on the board and other places mentioning this being associated with complex lifts...
lifts that employ multiple muscle groups but at the same time require a lot of coordination by the muscles in order to keep form
two particular types of lifts come to mind - the hang cleans (or any clean) and the chest flies
reason being is because the movements must be coordinated by the body, while at the same time they work several of the largest muscle groups
from what i gather also is that this "coordination" done by the muscle groups is what helps strengthen existing tissue as opposed to adding new tissue
anyone know if this is true/accurate information?
