Has anybody trained back and chest on the same day? Worth the effort? Im currently looking to change my routine and trigger some different growth. I train in the conventional back/ bi. Chest/tri. Shoulders/traps and leg day. Ill mix in abs and calves 3 days per week. And every other week ill give arms their own day along with the days I hit them with complementary muscle groups. Im open to any ideas as im looking to keep my body guessing.
