What can you do in half an hour? If you’re enrolled at 9Round, you can burn a boatload of calories, and kick down the doors to a healthier, fitter future. The multi-location gym’s signature kickboxing workout lasts only 30 minutes, but thanks to the top-notch instructors, the clean and stylish facility, and rotating workout routines, every second counts. Each workout is different, so exercisers might lift free weights, lace up gloves and throttle punching bags, or lob exercise balls onto targets strategically placed on the moon. But whatever the routine, it’s almost guaranteed to carve a sleeker physique.
