I do chest/shoulder/triceps 1 day hard! Then I do back/biceps one day hard! I work the back and chest hard so each gets 2 workouts a week. Then I do one arm day doing my long orangutan knuckle dragging arm workout. I love arm day because the results are immediate and obvious, you get what you pay for. As of 10/1 I am bulking again and will continue through the winter. 400 gram minimum protein a day and I am still loseing weight, building mass, and getting more defined especially in the arms.
