@ Karen - Way better descriptions of the moves, specific workouts within the programs focused on fat loss and strength, better warm-up strategy. After I read NROL I found myself better understanding the concepts that I had read in NROLFW -- its like a light bulb went off.

As for the break-in - its consists of doing two workouts (the number of times you do these two workouts in a week and for how long depend on the program you pick).

Yesterday I did Break-In Workout A and when I first looked at it looked really easy -- almost too easy. It went something like this:

Warm-up:
1) General Warm-up (5-10 minutes of whatever you want - biking, running, rowing etc.)
2) Semi-specific warm-up (I believe it was 5-6 different warmup including t-pushups, walking lunges with twists, inchworms, stability ball twists and one or two more I can't think of right now)
3) Specific Warm-up - Lou says that for every 50lbs of weight you are going to lift you do one warm-up set with half the reps for the first move (in workout A its the squat)

The actual workout consisted of:

Squats (2 sets/ 15 reps/ 60 second rest)
Alternating Set - Push-ups (2 sets/ 15 reps/ 60 second rest) and Swiss Ball Crunch (2 sets/ 20 reps/ 60 second rest)
Alternating Set - Static Lunge with Barbell (2 sets/ 15 reps/ 60 sec rest) and Two-point Dumbell Row with Elbow Out (2 sets/ 15 reps/ 60 sec rest)

Metabolic Conditioning: Essentially you pick whether you want to row, bike, run etc. and you go at a moderate pace for 2 minutes and then 1 minute as hard and as fast as you can. You do this for 19 minutes and as the weeks progress you up the number of times you do it.

I came out of the gym feeling like a complete fool for thinking this workout looked too easy. This morning I woke up and my legs felt like jello in a good way.
