FIRM and related titles (FitPrime, Kick Butt, Tracie Long, even some Jackie Warner is kind of AWT) all the way, baby! That's all I do for my strength workouts, really. I have done traditional weight lifting and I like it a lot, but AWT is fun because it's all about variety. I get so bored doing endless reps of a move that isn't challenging to me. Conversely, I get frustrated doing traditional cardio that's fast-paced and dancey. Old-school FIRM is awesome for variety, challenge, reasonable pace, and easy choreography. And on the slower titles, you can REALLY heavy up your weights, such as with Boomers or Tortoise. I find those two in particular to be insanely easy as far as learning the moves, but if you use really heavy poundage, you are a puddle on the floor afterward!
