LindsB: The front squat/push press is one of my favorites, too. Wait 'til you get to those one-arm dumbbell snatches in stage 3-- wheeee!
Happy to report that I now have my chin-up!!!!

I can do literally one per few hours-- try again in 5 minutes, 10, 30, whatever... nope.

(It's funny, it doesn't even feel that hard when I'm doing it, but afterward, I guess my muscles must be super depleted.) I'm definitely looking forward to stage 6 now, as I hope that I might be able to get up to 2 or 3 chin-up reps.
