ERIKA HAMMOND

WHO: Founding trainer at Rumble Boxing. SWEAT IN STYLE: “I love looking fresh when I’m working out. If I’m looking good, I’m feeling good. I find a lot of gear at Bandier (164 Fifth Ave., New York, 646-360-3345; bandier.com) and (shhh!) Forever 21 (50 W. 34th St., New York, 212-5642346; forever21.com)— you’d be surprised: cheap and cute!” POST-TRAINING TREAT: “Our studio is right around the corner from Juice Generation (109 E. 23rd St., New York, 212-531-1110; juicegeneration.com). I get the Peanut Butter Split smoothie and add dates. It sounds as good as it tastes!” OFFTHE- CLOCK FUN: “My favorite way to end a busy day is with a glass of wine in hand at Westlight, the rooftop at The William Vale in Williamsburg (111 N. 12th St., Brooklyn, 718-307-7100; westlightnyc.com), looking at the beautiful skyline of Manhattan.” Rumble Boxing is located at 146 W. 23rd St., 212-804-7918; rumble-boxing.com.
