i am passionate like crazy for rock climbing. but everybody here on trp talks about lifting to get bigger. that makes sense in a way, since all climbers in my gym are ripped, but more the lean, tough bodytypes.

i am wondering: why?

i want to gain much more. is there any way to put on a reasonable amount of muscles only with rock climbing and antagonist training afterwards? or do i HAVE TO start lifting to add massive volume?

thanks gentlemen
