The instructors at Core Group Fitness have shaped the physiques of U.S. soldiers, battled for glory in the professional MMA ring, and conquered distance events. But that doesn’t mean their fitness techniques are beyond the reach of an average Joe. To the contrary, their unique brand of cross-fit and interval training reroutes clients to healthy paths fast by matching proper nutrition with intense workouts. They often use battle ropes, sandbags, sleds, and other hefty pieces of equipment throughout classes.
