Infrared Does it Better
The ROWDY Mermaid is Belmar’s only infrared fitness studio, built for people who want more out of their training.
Infrared heat works deeper than traditional workouts, improving circulation, reducing inflammation, and accelerating recovery so you get stronger, faster.
From barre and intense core work to high-intensity training, every class is designed to challenge your body, sharpen your focus, and deliver results that last. Our studio is inclusive, supportive, and unapologetically rowdy — the kind of place where you can push hard, sweat hard, and feel at home.
Train smarter. Recover faster. Join the strongest fitness community in Belmar and Lake Como.

Infrared heat works underneath your skin instead of just warming the air around you. It gets into your muscles and joints, which means better circulation, less inflammation, and a faster bounce back after class. You leave sore in the good way, not the wrecked way.
-
Our original studio is at 1605 Main Street in Belmar, New Jersey. A second location is opening in Oakhurst in 2026.
-
Barre, core, pilates, resistance training, HIIT, and infrared training for every level, plus infrared spin, beginner spin, and step aerobics coming to the Oakhurst studio.

No! Every class is built to meet you where you are, whether that's your first workout in years or your five hundredth class with us.

Yes! You can drop in and try a class for just $32, or try an unlimited 2 weeks of classes for just $100.
