I'm trying to gain mass but so far I've only managed to tone up.
Weight; 154lb
Height; 6'1

Need to get to 170lb by next January (muscle), could that be done in 12 months?

Is it a good idea to do a few muscle groups in one day, or split them up over the week? Feel free to critique or add to. I'm working on a trial and error system with this workout
