I always preferred crushers to cgbp, crushers have been known to put undo stresses on the elbow which later in my training years came to be very apparent. However CGBP's also has been known to cause wrist issues, or aggravate existing ones. I suppose its a matter of personal preferences, then I discovered 2 arm overhead dumbbell extentions, superior stretch and a ton of weight can be used with these. they became my personal fave.
