Is there one workout that:
✅ A pregnant woman
✅ A CrossFitter
✅ An adult in their 70s
✅ Anyone rehabbing an injury
...can all participate in?
Yes. H₂shO™ CLASSICAL.
Before rock. Before pop. Before Broadway show tunes, Auto-Tune and TikTok trends… there was CLASSICAL.
It was radical. It was scandalous. It was rebellion in a powdered wig. Classical music was once the punk rock of its generation.
Scandalous. Explosive. Woke before woke.
H₂shO™ (pronounced H-two-show) CLASSICAL pairs the multi-directional movement possibilities of water with the musical textures of symphonic music to create the ultimate mind/body wellness combo. It's a great active recovery workout for athletes, and just as effective for rehabilitation or weekly mind/body relief.
Classical music has real brain benefits. It can:
Just as the original H₂shO™ is rooted in the traditions of musical theater, its CLASSICAL companion dives into a wide spectrum of music, pairing contemporary pieces with classical standbys. The playlist reflects our current culture and feelings; this isn't a tribute to dead composers.
Past CLASSICAL playlists have been curated by influential artists and musicians, including BBC presenter, author, and violinist Clemency Burton-Hill, OBE; two-time GRAMMY®-nominated musician and composer Theo Bleckmann; and jazz musician, composer, and educator David Hazeltine.

H₂shO™ CLASSICAL delivers the physiological benefits of vertical aquatic fitness and the cognitive rewards of music on brain neuroplasticity.
Make classical music part of your every day.
Beyond a workout H₂shO™ is about connection. The emphasis on "enter-train-ment" allows us to take out the mental and emotional experience of failing. Now you are free to explore your potential.
Unlock your inner shO-girl, shO-man, shO-person.
H₂shO™ (pronounced H-two-show) by Erwin R. González, is a musical fitness workout that delivers the Soul of Broadway and the Aliveness of New York City.
The name H₂shO™ is a portmanteau of the chemical formula of water H₂O💦+Broadway show 🎭. It all began as a shallow water, vertical fitness exercise class intended to be "less bootcamp" and more "CAMP".
As the popularity of this unconventional water aerobics program grew, it soon became a consistently waitlisted program offering at New York City's finest health clubs. Now the one-of-a-kind fitness events are hosted at NYC luxury coops, condos & rental properties. We also present private aquatic events.
From humble beginnings, the science-based, soul-nourishing, performance-enhancing musical workout has evolved. We offer more varieties of enter-train-ment experiences, both in-and-out of the water, connecting with athletes of all ages.
There are two aquatic classes:
There are two on-land iterations:
