Across three Tucson locations, Boxing Inc.'s instructors develop their classes based on the training regimens of real-life fighters, encouraging guests to bob and weave at their own pace. Students skip rope, pummel hanging bags, heave medicine balls, and push through cardio workouts to condition their muscles as they hone techniques in their choice of combat style. Muay thai kickboxing techniques demand strikes from all four limbs, and grappling classes teach takedowns from styles including judo, wrestling, and Brazilian jujitsu. For a cumulative battle strategy, MMA courses blend maneuvers from each school, inciting suspenseful spars between pupils not seen since the six-hour bare-knuckle boxing match between James Kelly and Jonathan Smith on December 3, 1855.
