Most people have to cut their workout in half dude, you have to cut yours in third. I'd back off to two exercises for five sets twice a week. Do different exercises on the second workout for the same 5 sets. I look at it as a half baked way of doing two one time a week workouts. Flat bench and DB press' one day and incline and decline the second. every three weeks, change your rep scheme from high to low.
