Carter - I agree on the lunges. I hate them so much!! My legs feel like jello at the end. I also hate the ab exercise the "jackknife" in Workout A stage 1.
Silverfire - If you still haven't crossed the threshold yet you should do a "mock" workout at home. Go through the motions of all of the exercises, then that way you might feel more confident going into the area with all the buff guys. What I found most intimidating was that I didn't know how or where to start, but after doing each workout once I feel like knew exactly what I was doing.
I am nearing the end of Stage 1. I have 4 workouts left to do but I have to travel next week. so I haven't figured out what I am going to do yet. I might try to workout at hotels. If that isn't possible I might take a break for a week, then finish Stage 1 and move right to Stage 2 without taking a break between the stages.
