I would say my gift has been my ability to create an inclusive fitness community and find innovative ways to integrate the arts into the fitness world.

Erwin Gonzalez is a New York City–based fitness innovator and multi-disciplinary creative with nearly 30 years of experience. A native Nuyorican raised in Hell’s Kitchen near Manhattan’s famed theater district, Erwin’s passion for theater, music, and film deeply informs his unique approach to fitness.

After studying theater and liberal arts at McDaniel College and Loyola University New Orleans, Erwin discovered his love for fitness post-college through an intense triathlon journey that challenged him to learn swimming, biking, and running competitively in just six months. This transformative experience sparked a lifelong dedication to health and wellness.

Certified as a Johnny G SPINNING® instructor in the mid-1990s, Erwin quickly became known for crafting indoor cycling classes as immersive musical journeys—long before the rise of SoulCycle and Peloton. His pioneering work was featured in Fitness Magazine and The Doctor’s Channel. Over time, he earned certifications in functional movement, active-isolated stretching, prenatal and gerontology training, among others.

Erwin’s career expanded into diverse fitness disciplines including strength training, balance, bootcamp, and personal training. He created the holistic KINETIC Sculpt program before answering a pivotal call to teach water aerobics—initially hesitant but ultimately discovering the creative freedom of aquatic fitness.

In 2015, Erwin launched H2shO™, an aquatic fitness program that blends traditional calisthenics and functional training with the artistry of Broadway and musical theater. H2shO™ is an inclusive, fun, and non-competitive experience designed to connect fitness, mental health, community, and culture.

H2shO™ became an official class at New York Health & Racquet Club in 2019 and joined Equinox Luxury Fitness Clubs’ schedule in 2020 as their only independent aqua program. Amid the 2020 pandemic, Erwin developed the land-based H2shO Strength & shO Tunes and launched shO LIVE!, an online workout community celebrating musicals and music.

H2shO™ continues expanding with luxury residencies and independent aqua classes. Erwin’s innovative, theatrical fitness approach has touched thousands and continues to inspire through creative collaborations and media appearances in Shape, Men’s Journal, GQ, and on major TV networks.
