The expansive interiors of Axiom's three fitness centers are packed in endless rows of weight and cardio machines, group workout studios, pools, and basketball and racquet courts to help its diverse client base whip into shape. The knowledgeable trainers lead patrons in pumping their bodies on the fitness floor, and instructors helm more than 100 Zumba, yoga, water aerobics, and Les Mills classes each week. In their performance center, the trainers customize one-on-one or small-group programs, such as Ax-Fit, which helps firefighters, law-enforcement officers, and those in the military increase their power and endurance, and Sport Performance, which helps athletes train for their competitive physical pastime of choice. Kids aged 7 and older can hone their coordination and improve their athletic performance and growing up too fast in Kids Performance sessions that run hourly from 3:30 to 7:30 p.m., and older adults can stay in shape in the Silver Sneakers program. After sweat sessions, patrons can recharge at the Fuel Center juice bar, which serves up crushed-fruit smoothies, and nutrient-infused coffee and chocolate shakes.
