I'm assuming a bodybuilding contest?
No less than 4 lifting days and 3-4 cardio days. I would say:
mon- chest, cardio
tue- delts, traps, cardio
wed- back
thur- legs, cardio
fri- arms, cardio
sat- off
sun- off
OR:
mon- chest, tris, cardio
tue- back, bis, cardio
wed- off, cardio optional
thur- delts, traps, cardio
fri- legs, cardio
lifting with moderate to light weights failing in the 12-20 rep range and lots of supersets. 5 lifting days is also to keep your mind on the diet so you don't cheat @2.5 weeks out you CANNOT cheat at all. lifting about 30min-45min a session it should not be so intense that you get too sore but you do need to push yourself hard. cardio sessions should be at 45-60 minutes
btw: you should be at 5-6.5% bf right now, and you should be tan!
