All barbell work. 2-3 exercises a body part. I would do 2 body parts a w/o. Maybe like Mon, tues, thurs , fri. split. I would try and keep the reps in between 6-10 and like 3 working sets each exercise.
mon: chest and tri's
tues: Back and bi's
thurs Legs and abs
Fri: Shoulders and traps
Just keep it simple in the beginning. Trust me you'll gain as long as your eating too. Good luck
