I do something like this
Monday: All over upperbody (Chest, arms, shoulders, back, abs) Heavy day
Tuesday: Either off or cardio
Wednesday: Either off or Cardio (Depends on tuesday)
Thursday: Chest, Shoulders, Tris (Pushing Muscles)
Friday: Back, Biceps, Traps (Pulling Muscles) and abs
Saturday: Cardio if I can be f**ked :lol:
Sunday: Off
If I don't drink I lose 1kg a week doing that workout on about 200g of protein and 200g of carbs (No idea what my fat intake is but it's pretty low. Don't do legs since it doesn't help with my cardio (legs too sore) but when I decide to bulk i'll start doing my legs again no doubt.
But yeah, there are heaps of different combinations - that's just mine. What you need is to find yourself a structured workout that works best for you. I suggest getting one of the trainers at your gym to give you a program based on the goals you want to achieve.
