I follow my workouts in a Workout 1, Workout 2 fashion instead of a Monday workout, Wednesday workout.

My current split is:
Workout 1- Back and Calves
Workout 2- Chest and Side Delts
Rest Day
Workout 3- Quads and Biceps
Workout 4- Triceps and Hamstrings
Rest Day
Repeat

My workouts are alternated and changed often but here is a possible workout:

Workout 1
Barbell Rows x 4
T Bar Rows x 3
One Arm Rows x 2
Standing Calf Raises x 5

Workout 2
Bench Press x 3
Inc. Bench Press x 3
Dumbbell Decline x 2
Side Laterals or Upright Rows x 4-5

Workout 3
Deep Squats x 4-5
Hammer Curls x 6
Behind the Back wrist curls x 3-4

Workout 4
Overhead Triceps Presses x 3
Kickbacks x 3
Stiff Leg Deadlifts x 3
Leg Curls x 3

This is a great workout for mass. The reps are from 5-8 on most. I was following much more complex programs before and I have used ALOT of different programs but I love this one as it is kind of a combination of all the things that work for me.
As for cardio I don't have a planned cardio routine in the off season. Just kicking a footy or something like that every so often keeps me fit. My diet keeps me lean.
