Re: Changing up my routine could use some advice.
I always like to make sure to separate those so I can make sure my chest or back get the most attention. Arms are relatively easy to train and grow, chest and back are much more complex. I use a rolling split of one bodypart per day with the exception of bi's and tri's, those are trained together. If you are lifting really heavy, the major bodyparts should be separate.
