BEFORE YOUR FIRST SESSION
Common questions.
What to expect. How to prepare. Where to begin. A few answers before you find your first session.
Still have a question? Ask the H2O team ↗
What should I expect at my first session?
You’ll start with a land-based warm-up and guided breathwork, followed by underwater workouts and aquatic conditioning scaled to your level. First-timers receive an Intro Orientation with a dedicated coach to welcome you into the water and our programming. Expect a progression of three to four workouts.
Do I need to be a good swimmer?
You don’t need to be an advanced swimmer. Being able to swim 25 yards comfortably is recommended to get the most value out of class. Your coach assesses your comfort in the water during Intro Orientation and helps you choose the right starting point.
Do I need to have a good breath hold?
No. We build that capacity through progressive training, breath control, and recovery. You start at your current level and develop from there. A long breath hold is not a prerequisite.
Which session do you recommend for my first class?
We recommend Sunday All Levels sessions in La Jolla, San Diego, or Kapolei, Hawaii, for your first class. You’ll receive an Intro Orientation with a dedicated coach. Check the schedule for current times and availability.
How do you approach safety?
We program to build capacity and tolerance for rising carbon dioxide (hypercapnia), not to pursue oxygen deprivation (hypoxia) or failure. Intensity follows readiness, with direct supervision, safety swimmers, and structured recovery. Underwater breath-hold activities carry risk. Never practice underwater breath holds alone or hyperventilate before submersion.
How does this translate outside the water?
Practice settling your breathing and attention, then apply that composure beyond the pool. The goal is to carry those skills into your sport, your work, and everyday life.
What do I bring, and how do I book?
Bring active swimwear, a towel, goggles, and water. Book through the San Diego or Hawaii schedule. Single sessions, class packs, and memberships are available, with current pricing shown at booking.
