I am interested in what folks are doing for training splits - I am currently putting together a new routine and am looking at a 3-day split (Push, Pull, Legs) similar to the one on EXRX.net; however, I think that a 3 day split might either not cover enough muscles sufficiently or may make my lifting sessions too long. Any suggestions on training splits (# of days, muscle groups, rest periods)? Thanks for any help.
