Behind the Serenité at Camelback project

The Diamond in the Rough

Serenité at Camelback set out to craft a fitness amenity that responds intuitively to members’ needs while exceeding member expectations. Every element, from sleek, high-performance equipment to carefully considered finishes, was designed to impress and delight. The space harmonizes seamlessly with the clubhouse’s other other premium amenities.

Project leads consulted industry experts and reviewed competitors to find the right fitness partner.  Advantage proved to be a natural fit, combining technical skill with a shared vision for a fitness center that complements the clubhouse’s upscale offerings.

A Perfect Fit

Advantage Hospitality Sales Manager, Christine Watson, guided the project through multiple layouts and product considerations, ensuring every aspect met the highest standards. Every revision brought  the layout closer to meeting practical needs while reflecting the sophistication of the clubhouse.The result is a space that transforms how the fitness center supports wellness, lifestyle, and community.

“We wanted to deliver a caliber consistent with the rest of the clubhouse and resort. Mission accomplished.”

Gregg Bittner, CFO, Serenité at Camelback

Style & Strength

The design and features of the room itself are impressive: wooded mountain views, sunlight flooding in along the row of cardio, timeless exposed beams, and modern lighting. Like many of Serenité’s amenities, these choices blend sleek elegance with comforting warmth, setting a tone that naturally draws residents into sync with the space—whether they’re unwinding by the fireplace, treating themselves to a spa service, or finding focus during a workout. The space is as purposeful as it is beautiful, designed to support every member’s routine.

Gym fitness equipment

The Art of Motion

Step inside, and the fitness center is alive with motion. A member on a strict training regimen can move from the Precor Resolute Multi-Station to the dumbbells and benches, maximizing the strength layout for efficient, targeted workouts. Another member focused on health and vitality may flow from the Precor treadmill to the Peloton Bike+ and Row, leveraging touchscreen consoles and engaging content to customize each session.

Workouts feel smooth and natural with equipment and design working together to make every session rewarding, and in alignment with the larger community lifestyle.

“Members are in love with the fitness center and it is one of the main features of our clubhouse.”

Gregg Bittner, CFO, Serenité at Camelback

A Legacy of Wellness

Designing the fitness center at Serenité wasn’t about filling a room with machines—it was about encapsulating a lifestyle that prioritizes wellness. The client envisioned a space that felt refined yet vital, a natural extension of the property’s elegance. Advantage answered with the technical insight and design fluency to match. Together, they selected premium equipment, integrated custom details, and refined the layout until every choice resonated with the broader vision. The result is a fitness center that lets members pursue wellness on their own terms, within a space that is both sophisticated and inviting.
