Cross trainer by day, boxer by night, Jess Sims brought her collegiate athletic capabilities to NYC and teaches a HIIT total body workout at the Fhitting Room. Her class truly tests your strength with kettle bells, rowing machines, and TRX just to name a few. When she's not running you through circuits, she teaches another HIIT boxing class at Shadowbox. Train with her and you'll be a total knockout. Check out her Fhitting Room schedule and take one of her ShadowBox classes!
