I'm having trouble choosing between a bunch of routines that look pretty appealing. A few people on these forums mentioned Renegade (push/pull) as a very good one, and I've also seen that Mike Mahler seemed to like Iron Manual. I'm not interested in losing weight, 15 y/o male, skinny, hoping it will be a routine that's fairly difficult. I have about a year of weight lifting experience. Baseball season is coming up, so preferrably something that gets work in the legs, core, back, and to some extent arms.
If anyone could help me out here, that would be great.
