Round House Fitness is a boutique gym at 126 B Avenue in Coronado, founded by Dan Boyle — a fourth-degree black belt in Taekwondo who opened the original Coronado Training Center at this address in 2007 and rebranded to Round House Fitness in 2023. The second-floor studio near the intersection of B Avenue and 1st Street offers private training sessions, group fitness classes, and martial arts-influenced conditioning, drawing on Boyle's decades of teaching Taekwondo to thousands of Coronado kids and adults. The 92118 location is one block from the Coronado Ferry Landing, making it accessible to ferry commuters who fit a Coronado gym session into their cross-bay routine. Flexibility and recovery work pairs naturally with the strength and striking formats here, and Popflow Coronado at 176 C Avenue offers yoga, Pilates, and sculpt classes one block east of the studio. Boyle's coaching staff includes certified trainers with specialties across kickboxing, functional fitness, and mindfulness-based movement. The B Avenue address sits within walking distance of Orange Avenue, Hotel Del Coronado, and the bayfront parks that line the Coronado Ferry Landing waterfront. Outdoor training sessions use the flat, open space at nearby Coronado Tidelands Park on the bay side of the island, where the waterfront setting adds a location advantage that few Coronado Island gyms can match. Boyle is active in the Coronado community through Sacred Heart Parish, Little League coaching, and long-running involvement with Coronado schools. The gym operates six days a week from the second-level space above B Avenue, across the parking lot from Smart & Final.
