Sara Colletti-Youmans

Certified Personal Trainer & Group Fitness Instructor

Since 2013, Sara has been helping people transform their bodies, minds, and confidence through movement. A lifelong athlete and wellness enthusiast, she brings energy, expertise, and heart to every class and client.

Sara’s professional journey began in 2012 at Focus Integrative Fitness, where she fell in love with sharing her passion for health and wellness. Through her studies in anatomy, kinesiology, and bioenergetics, she gained a deep understanding of how the body moves and thrives. From there, she brought her expertise to Equinox, built a thriving concierge fitness company in the Hamptons, and is now proud to call the North Shore of Long Island home.

Her philosophy is simple: health is a lifestyle built on movement, nutrition, and a positive mindset. Her mission is to create an environment where every client can unlock their healthiest self and have fun along the way.

In 2025, Sara and her husband Ross welcomed their baby boy, sparking a new mission: to create a supportive fitness community where parents (and families of all kinds) can bring their little ones and make wellness a way of life.

Ross has an athletic background and discovered early on that playing sports was one of his greatest passions. This passion naturally led him to excel in his sports endeavors, where he realized that the process of improving through fitness offered not only physical benefits but also tremendous health and mental advantages. Helping others on their fitness journeys brought him true happiness.

Ross began his career as a Personal Trainer at Equinox in Tribeca, NYC. Through the UCLA-partnered Equinox Fitness Training Institute and other educational programs, Ross advanced to a Tier 3Plus Personal Trainer. He worked with a diverse range of clients, helping them achieve goals such as weight loss, muscle building, marathon training, athletic training, and injury recovery. His dedication to helping others inspired him to take on mentorship roles within Equinox, eventually becoming a Fitness Manager at the Equinox SoHo, Equinox Williamsburg, and Equinox DUMBO clubs. He was then promoted to Personal Training Manager at Equinox DUMBO, where he led the Personal Training Department.

Whatever your fitness goals may be, Ross is excited to share his passion for results-based programming and training to help you achieve them!
