Hey guys how's it going. So I was just curious on what y'all think about chest/back routines same day? I know everyone responds different and yada yada. I've been doing chest, back, legs, arms routine for 8 weeks during my cycle. So today I'm Gona switch things up and do chest and back for final 4 weeks of my 12 week test only cycle. Wana keep the training fresh and shock those muscles. Plus that was always Arnold's routine so can't hurt. I guess I'm just wondering what everyone thinks about it? Do they feel the results are better with doing big muscles groups on their own separate days or with the mix up. Again, I know different stimulus can spark new growth, just looking for opinions on splits and such....thanks guys!
