Here's a very good 3 day split (full body routine)
A good workout with plenty of rest, You WILL grow!

Press behind neck: 3 x 10
Squats: 3 x 12 (alternate with deadlifts, Day 1 - squats, day 2 deadlifts and so on)
Flat bench press: 3 x 10
Lat pulldowns: 3 x 12
Close grip bench press: 3 x 10
Barbell curls: 3 x 10
Bench dips(feet raised): 3 x 12

Abs:
Flat leg raises: 2 x maximum
Crunches: 2 x maximum
Bar twists: 2 mins approx.

Note:
Keep the rest periods as short as possible so the pump stays strong.
However, should you feel that you need more recovery time - take it.
The advantage of such a workout is mainly balance. Everything is and should be hit. Again, and I stress it strongly, when you should rest and take time off PLEASE do it. It will be of an advantage to you. Should you wish to train the abs first as part of the warm up then do it, no problem. Alot of people prefer to do it this way rather than have to do them at the end!
