I do Abs every other day, and cardio 3 days a week, right before i lift.

looks like an over tranning workout your doing a lot
for wanting to gain both size and strength
try your sets at 5-6 and your reps at 6-8
stick to the basic movements
i think on your chest you gotta do flat bench
and try and get your work out to 3 days a week those muscles need rest, helping you tweek your workout is no problem what are your stats age, weight, bf etc

read http://www.steroid.com/workout.htm its a good start

All I know is that with a routine like that, I wouldn't be able to open my car door, but that's me :) . Sounds good, but don't burn out. Better to pace yourself, 6 days a week is quite a bit, bro. I personally, work out 4-5 days a week, so I don't get burnt out. More power to you if you go 6 action-packed days like you listed. But like I said, definitely looks like a good routine.

BRO YOU ARE EXTREMELY OVER TRAINING. SINCE YOU WANT TO GAIN SIZE AND STRENGTH, I WOULD GO WITH LESS REPS AND SETS. FOR CHEST I WOULD DO 4-6 EXCERSISES 2-3 SETS 6-8 REPS EACH. LEGS SAME BUT 6-10 REPS. YOUR SMALLER MUSCLES LIKE CALVES, BI,TRI, TRAPS,FOREARMS YOU NEED LESS, YOU ARE OVER TRAINING THEM. UPPER BODY 6-8 REPS, LOWER 6-10 REPS, STAY WITH 2-3 SETS 3-5 EXCERSISE. BY DOING HIGH REPS YOU ARE DESTROYING NATRURAL TEST, GLYCOGEN LEVELS (SORRY CANT SPELL RIGHT NOW) STICK WITH NO HIGHER THAN 10 REPS. TAKE YOUR SETS TO FAILURE EVERYTIME.

Over training Bro,
general rule I stick to:
Small muscles go with 2 exercises 3 sets each
larger muscles go with 2 or 3 complex exercises (3 or 4 sets) and 2 more isolated exercises (3 sets)

Example: Mon:
Shoulders
DB Press or military press (4 sets - at least 2 light sets for warmup)
Upright Rows (3 sets)
Lateral Raises (2 sets seated, 1 set standing)
Front raises (seated 2 sets)
Forearms:
Nothing crazy, go with 2 exercises (3 sets each)
If you want to do the neck machine, go with 2 sets each side, not 4. If you want huge forearms just don't use straps, they will come along.

My question for you is: What about deadlifts? It is THE best exercise for your back, but you do not even include it.

I agree with KINGLYON8801, all sets to failure. If you can do more than 8 reps on complex movements, you didn't go heavy enough.

There seems to be a common trend in the reply's. I am going to sit down and revise my workout tonight. I'll toss the new one up and see what you guys think.
Thanks

I agree with what everyone is saying. Heavy volume workout. Focus on more compound movements, less exercises. Also, because of the extensive shoulder workout, you need a rest day in there before doing back where you will tax the rear delts as well. Overall, I personally thing going six days in a row will be extremely counterproductive. Muscles grow during rest, bro. One more thing... on shoulder day, start with the pressing movement, then do the raise movements, but cut down on the amount of exercises.
