Madhouse Dance in Encinitas's New Encinitas corridor is a women-owned, LGBTQ+-affirming dance-fitness studio that launched its signature Redroom Dance Cardio class format in 2021. The HIIT-style choreography sessions blend explicit-music floorwork with full-body cardio intervals, creating a higher-impact counterpart to the isometric barre and balance sequences at barre3 on South Coast Highway 101. The Encinitas studio opened in 2024 as the company's second San Diego County location, occupying Suite E at 260 North El Camino Real with a blackout lighting rig designed to replicate a nightclub environment during classes. Class formats include the flagship Dance Cardio, a beginner-to-intermediate choreography tier, and a technique-intensive track, each incorporating active-recovery stretching protocols that overlap with the practitioner-assisted flexibility sessions at Stretch Zone. The nightclub-format Redroom sessions utilize a 1,200-watt sound system synced with programmable LED strips and a mirror-free wall design engineered to reduce self-monitoring and increase uninhibited movement.
