ONSITE CLASSES

Come Join Us!

We offer heart-pumping, dynamic, musical, and fun 45-minute HIIT classes designed to sculpt your entire body. No two classes are ever the same. Join us for a live class to experience the Fitness Underground difference. Class sizes are kept intentionally small to provide personal attention, social distancing, and our thorough in-class equipment cleaning protocol.
