Workout Routine

Hey guys and gals at MFT :)
First of all, i would like to say that this site is AWESOME!!

I'm here to share my workout routine so that i can get your input or suggestions on how i can improve my workouts; whether i'm over-training or under-training certain muscle groups etc.

Basically, i break my workouts into 3 groups, Workout A, Workout B and Workout C. I perform each workout on separate days and cycle through them (Monday - Workout A, Tuesday - Workout B, Wednesday - Workout C, Thursday - Workout A, etc.). This means that i have 2 days rest for each muscle group.

My workouts are as follows.

Workout A

Chest:
- Diamond push-ups, max reps
- 3 sets of dumbell-press, 12 reps per set
- 3 sets of dumbell pull-over, 12 reps per set
- Incline push-ups, max reps

Biceps:
- EZ barbell bicep curls, 3 sets. Set 1 with lighter weight 12 reps, set 2 increase weight 10 reps, set 3 increase
weight 8 reps.
- Preacher curls, 3 sets. Set 1 with lighter weight 12 reps, set 2 increase weight 10 reps, set 3 increase
weight 8 reps.
- Concentration curls, 3 sets. Set 1 with lighter weight 12 reps, set 2 increase weight 10 reps, set 3 increase
weight 8 reps.
- Seated dumbell curls, 2 sets. Set 1 with 12 reps, set 2 15 reps.
- Seated dumbell hammer curls, 2 sets. Set 1 with 12 reps, set 2 15 reps.

Triceps:
- Overhead dumbell triceps extention, 3 sets of 12 reps
- Skull crushers, 3 sets of 12 reps
- Bent over triceps kickbacks, 3 sets of 15 reps
- Triceps Dips, 2 sets, max reps for each

For the biceps and triceps, i alternate the workouts. This means i do the first bicep workout followed by a tricep workout. Then, the next bicep workout followed by the next triceps workout etc.

Workout B

Abs:
- I use the ab circuit workout done by Julien and Jamo :) - 5 sets for the circuit

Legs:
- Dumbell squats, 3 sets of 12 reps
- Calf extentions, 3 sets of 15 reps

Skipping for 15 minutes.

Workout C

Shoulders:
- Arnorld press, 3 sets of 12 reps
- Seated dumbell press, 3 set of 12 reps
- Side lateral raise, 3 sets of 12 reps
- Front hammer lateral raise, 3 sets of 12 reps
- Bent over lateral raise, 3 sets of 12 reps

Traps:
- Front barbell shrugs, 3 sets of 15 reps, increasing weight after each set
- Back barbell shrugs, 3 sets of 15 reps, increasing weight after each set

Lats:

So basically, this is my workout routine. I hope i can get some tips to help me "shape up" my routine :)
