"Ever hear of P90X? My brother and his wife are both in the Air Force; they do marathons and triathlons. I went [to visit them and she's doing P90X]. I couldn't keep up with her — and she'd just had her first baby four weeks ago. I was like, This is bullsh*t! I will perfect this thing! So usually, I wake up and do an hour of cardio, then an hour of P90X or yoga, then a half-hour of warm-up [during show rehearsal]. I do that six days a week."
