Kasey P.

"After college, I went to nursing school and we had one of these machines that would tell you basically how healthy you are or how out of shape you are . . . and it said I was pre-hypertensive. I'm gonna be a nurse, you know—if I want my patients to believe that, you know, by diet and exercise, you can have good health or whatever . . . I mean, who's going to believe that coming from an unfit, unhealthy nurse who obviously doesn't exercise? Day by day, week by week, the workouts got easier, and just when they started getting easier, they switched 'em, and then they switched 'em back again because the muscle confusion, they switch it up so you never hit a plateau, which is a good thing. Plateaus are bad . . . this will get your heart pumping . . . in 90 days, I lost 30 pounds. Yeah, 30 pounds. People that hadn't seen me in a few years were like, 'Oh my god, Kasey, you look amazing.'"
