Meet Mason

Mason blends the form-focus of classical Pilates with athletic, creative programming and a modern understanding of movement. Launching this summer in residence at Montauk Yacht Club, Mason offers private sessions and intimate four-person classes designed for maximum attention, correction, and progression.

Using premium reformers, towers, chairs, weights, and props, every session is challenging, hands-on, and constantly varied. A workout that feels personal, social, and genuinely fun.

This is the first expression of Mason before our members-only Tribeca flagship opens this fall: a permanent home for precision training, community, art, and recovery, complete with a lounge, wellness suite, sauna, cold plunge, and regular social programming.

Using premium reformers, towers, chairs, weights, and props, every session is challenging, hands-on, and constantly varied. A workout that feels personal, social, and genuinely fun.

/ The FOUNDER

Aly berger

Aly Berger founded Mason Pilates after years of searching for a workout that combined athletic intensity with the precision of classical Pilates.

A former Dartmouth athlete, Aly first turned to Pilates after a physical therapist recommended it for back pain. After trying studios across New York, she found that the hardest workouts often lacked form and correction, while traditional Pilates rarely delivered the challenge she craved.

Her perspective deepened while living in Bondi, where boutique fitness felt social, design-forward, community-driven, and genuinely effective. It clarified what she felt was missing in New York: serious training paired with beauty, hospitality, and culture.

After leaving her growth equity career, Aly trained intensively in Los Angeles and became certified in a contemporary Pilates method rooted in anatomy, control, and athletic programming. Today, she teaches everyone from first-time clients to professional athletes to clients rebuilding strength after surgery and injury.

At Mason, every class is taught by Aly and capped at four clients, allowing her to know each person, understand their body, and tailor the work like a private session.

Mason is her answer: athletic Pilates, premium equipment, real correction, and intimate small-group training in a luxury, social environment.

/ The METHOD

Athletic. Personal.

Mason combines contemporary Pilates, classical roots, and modern movement science to create workouts that are challenging, constantly varied, and deeply considered.

Aly’s philosophy is to keep the method evolving — drawing from the latest research in biomechanics, strength training, and movement patterns while tailoring the work to each individual client. When possible, clients are thoughtfully paired by level, goals, and energy, creating a more private-feeling experience with the social connection of a small group.

Using premium reformers, towers, chairs, weights, and props, every session is designed to build strength, mobility, posture, and control. Four-person classes allow for real correction and progression, while private sessions offer a fully tailored experience.

The result is a workout that feels hard, smart, social, and never the same twice.
