A Full-Body Workout at Betsey Johnson

BETSEY’S FULL-BODY WORKOUT: At Betsey Johnson’s Monday fashion show, her signature walk-off cartwheel was the least of it. The designer launched activewear by leading 20-plus models in crunches, push-ups and other gut-burning calisthenics. At one point, each hoisted two empty Champagne bottles of Betsey Bubbly for what Johnson said led to Michelle Obama arms. After the show, guests traipsed over the models’ pink yoga mats imprinted with “BJkicksA.” Not everyone left motivated: Steve Madden’s young son said, “Mom, the bad thing is the only snack is cupcakes.”
