Breathwork + Underwater Training at KAN Tulum

A RARE TRAINING ENVIRONMENT

The 3.5-Meter Underwater Gym Pool

KAN Hotel Tulum has built a purpose-designed 3.5-meter-deep underwater gym pool – one of very few facilities of its kind. After each breathwork session, you will move into the water for structured in-water training that applies the breath control techniques you just practiced.

This is not a standard pool. It is a controlled, deep-water environment built specifically for underwater performance training – combining depth, clarity, and safety in a single purpose-built space.

Each Session Includes

• 9:00 – 10:15 AM — Guided breathwork class
• 10:30 – 11:00 AM — Protein shake or health juice
• 11:15 AM – 12:15 PM — Poseidon training session (free weights, CO2 tolerance, and swimming in the 3.5m pool)

The combination of structured breath control followed by immediate aquatic application creates a training experience unavailable anywhere else in Tulum.
