I've been reading that pullovers are considered by some to be like the upper body equivalent of the squat (great mass builder, works the whole upper body, etc. eg: here). It doesn't seem to be an exercise very often recommended by peeps on this forum, just wondering what people's opinions of this exercise are? It's not an exercise I particular like, I mean I'd prefer to do dips and bench presses for my chest and rows and chins for my back. However, if it is good for adding mass then I might consider incorporating it (plus my gym has a pullover machine, so I can use that).
