Hi everyone,
I've finally gotten desperate enough to stop searching information on the forums and directly ask for help.

I currently work 10 hour days, 5 days a week and head right to school for 4 hours after that. I've recent begun working out on my lunch breaks and have probably 30 solid minutes of workout time before I need to head back to work.

Here is the schedule I'm running:
Mon - Bi/Tri
5 to 6 exercises
3 sets, 8 to 12 reps

Tues - Chest
3 to 4 exercises
3 sets, 8 to 12 reps

Wed - Cardio (Steady State)

Thurs - Back
3 to 4 exercises
3 sets, 8 to 12 reps

Fri - Kickboxing Class/Abs

Sat - Rest

Sun - Legs/Shoulders
6 to 7 exercises
3 sets, 8 to 12 reps

Diet is pretty clean. Average day:

Breakfast - Protein smoothie
Lunch - Chicken breast with a V8
Snack #1 - 1cup fat free cottage cheese with 10 almonds
Snack #2 - Chicken breast with cayanne pepper or lean kielbasa
Dinner - 1cup quick oats with 1 scoop chocolate protein powder

My thing is that I lack the time to incorporate a really decent workout schedule but I want to fit in as much as I can. I'm seeing a lot of mass gains instead of losses so I'm wondering if I should do more cardio or higher reps on my lifting (I lift heavy). Maybe I'm eating too much?

Any suggestions? I could really use some help! Thanks in advance.
