When it comes to middle-whittling, Pilates can't be beat, but doing the same exercises over and over can get dull after a while. (And when you're bored, your muscles are too, which can stalemate the results.) So we asked Los Angeles–based instructor Juliet Kaska, the pro responsible for helping to sculpt the bodies of sexy celebs Stacy Keibler and Kate Walsh, to design a routine that shakes up six familiar moves.
"By incorporating either a ball or resistance band, you engage more muscle fibers and improve your form, making every exercise more challenging and increasing the effectiveness of your workout," she says. In other words, those bored abs and arms and snoozing legs and butt are about to get one helluva wake-up call!
How it works: Three to five times a week, do 2 sets of 10 reps of each move in order. Rest for up to 1 minute between exercises.
You'll need: An 8-inch rubber ball and a resistance band. (A mat is optional.)
