I'd like to start with a little background information. I'm 21, 5'11, 190lbs and I've been training for 5-6 years. My goal is to finally bulk up to 225. I want to focus on both strength and size. I did 5x5 before and I didn't like it too much. I'm thinking of using a Push/Pull. I read that the body knows movements, not muscle groups so the push/pull works well for that. Anyways here is the proposed routine. Exercises are not set in stone, just what I have come up with so far.

Day 1 Push
Flat bench 4 sets
Weighted Dips 4 sets
Military Press 4 sets
Close Grip Pres 3 sets

Day 2 Rest

Day 3 Legs
Squat 4 sets
Deadlift 4 sets
Leg Pres 2 sets
Calve Raise 4 sets
Abs

Day 4 Rest

Day 5 Pull
Weighted Pull-Ups 4 sets
Bent Over Row 4 Sets
Close Grip Seated Rows 2 sets
Bicep Curl 3 sets

Day 6 Repeat

Now as for the rep range I'm thinking 5-7. Is there any reason to go over 7? The more reps I do the less weight I can use, so that would be counter-productive to gaining strength and size right? I will also be alternating the Flat Bench with Incline bench. Incline bench hammers the delts more so should I do less shoulder work on the day I do the incline bench?

So what do you guys think? Am I on the right track? Any suggestions are welcome.
