Thread: My routine; few questions also

Hey guys I have a few questions, is it better to train all muscle groups in one day or to split it up or does it come down to preference?

My goal is to be leaner, I'm not trying to bulk.

Right now the supplements I'm taking are:

Precision Whey, Muscle Milk (I combine 1 scoop of each, take it pre-workout, PWO, and before sleep)
CEE from BN (2G before WO, 3G PWO)
Fish Oil (2 in the morning, 2 before lunch, and 2 before sleep)
One a day multi vitamin for energy (Uh I don't know if I should be taking this or a more specific vitamin)
Rev XP (2 in the morning, 2 mid afternoon, supposed to be a fat burner, but I like it cause when I take it before my cardio I feel the "burn" much earlier than I normally do)

I live on campus so my diet really revolves on whats being served, luckily for me during breakfast and lunch my school always has two of the same things availible.

I eat a healthy breakfast (oatmeal no sugar, egg whites, skim milk, OJ, and an apple)
Decent lunch (usually something with chicken breast)
and a kind of decent dinner (whatever seems healthier schools serving)
And I drink enough water that I piss every 5 minutes, which gets annoying, but I've grown into the habbit of drinking water when ever I'm bored.

As of right now my lifting days last me around 2 hours, starting from my pre-work out stretch to post-work out stretch.

I'm still a newb when it comes to naming all the excercises so sorry if I really murder some of the names, but I do my lifts in this order (some days I randomly switch them up);

(for all excercises: 3 sets same weight, 15 reps or till exhaustion. With anywhere from 60-90 seconds in between each set)

Bicep Curls (Hammer, regular, and the one that combines both)
Dumbell press laying on my back
Leg Press
Calf Raises
Bench machine seated
Leg extensions
Butterfly machine
Abs machine
Military press
Abs (bicycle)
Tricep Extensions
Lateral Pulldown

Is there anything wrong with what I'm doing now? I've noticed decent results so far, in terms of being leaner and stronger I'm liking my progress so far. So I really wanted to see if there was anything I would need to change or if what I'm doing is fine. I know that in reality only I can see whether what I'm doing works for me or not but having a second or third opinion would be nice.

Also I've a question about my reps, is it alright to just do my sets with the same weight and make my goal be 15 reps total, or would it be more beneficial for me to use progressive resistance increasing weights and decreasing reps?

Thanks.

Thanks I'm reading it now.
