Mermaid workout classes are the newest way to experience your hotel pool while traveling. Hotels.com is launching mermaid workout classes at three luxury hotels in Spain, Japan, and Mexico, beginning in September, so you can channel your inner Ariel.

While it’s obviously a good excuse to dress up in a colorful costume, the class is more than just a photo-op. Led by a “professional mermaid,” the classes are a great underwater workout and include a variety of exercises.

Hotels.com first conceived these mermaizing classes after a survey that concluded just how much people enjoy dressing up, and indulging in fantasy. The study found that more people would be likely to take part in a mermaid-themed workout at a hotel than hot yoga or Barre — which makes sense, since an underwater mermaid class sounds a whole lot more appealing than yoga in the sweltering heat.

The special classes will be held at the Zafiro Palace Palmanova hotel in Mallorca from September 20th-22nd, the Kanucha Bay Hotel & Villas in Okinawa, Japan from September 17th-21st, and the Camino Real Polanco Mexico in Mexico City on September 1st, 8th, 15th, and 22nd.
