It's an unexpected place to find a treadmill. The grand stone mansion that makes up Belfiore Salon & Day Spa and Belfiore Fitness Center teems with lush carpets, ornate furnishings, and framed art—even the changing room swaps out drab lockers and benches for dark wood cabinets with brass hardware and tufted leather seating. But despite its sumptuous appearance, Belfiore Fitness Center exists for the sole purpose of helping its members get healthy. In service of this goal, elliptical machines, treadmills, and recumbent bikes line the sun-drenched fitness area, helping users burn calories as a bounty of weight machines and free weights stand at the ready to build strong biceps or a new governor of California. Members can also follow personalized regimens in personal training sessions. Once workouts are complete, guests wind down in the dry sauna, the steam room, and the Jacuzzi, or recharge in the WiFi–equipped coffee bar.
