Like tattooing gills on your jugular and subsisting entirely on algae, learning how to swim helps you better understand fish. Get closer to your finned friends with today’s Groupon: for $33, you get four group swimming lessons (a $65 value) at SwimLabs Swim School, with locations in Centennial and Highlands Ranch. SwimLabs offers group lessons for children ages 3–10, but clients older than 10 or interested in other programs may use the value of this Groupon toward any combination of SwimLab lessons. The registration fee is waived with this Groupon.

SwimLabs Swim School's staff of formidable freestylers helps clients improve their subaquatic skills during lessons conducted in state-of-the-art Endless training pools. Within each Endless pool, an internal impeller creates a central current that provides hydraulic resistance for more advanced trainees; neophytes can move with the gentle flow while building trust in their own buoyancy. Each pool also features 360 degrees of underwater cameras, which teachers and students can utilize to determine needed technique adjustments and swimsuit-neckline alterations.

Group classes impart skills to beginner and advanced fish in half-hour sessions that meet once weekly for a month. Class sizes never exceed four pupils, ensuring that each student receives personal instruction while honing all four competitive strokes, kicking form, and underwater breathing. With dozens of classes scheduled each week at the Highlands Ranch and Centennial locations, clients can work salubrious swim workouts into schedules already loaded with career obligations and underwater-chess tournaments.
