March 25 · Jonathan JabbourI was in the area for a work event and wanted access to powerlifting equipment for a few days. This gym has a lot of powerlifting and machine space, the bathrooms and changing areas are clean, and the community and vibes are among the best I've experienced at powerlifting gyms. Ian was a great help setting me up with the week pass and key fob, and made the whole process to getting all that super straightforward. Would definitely come back for meets or if I'm ever in the area for a few days again.
March 20 · Aram CariagaFitness Underground is as close to perfect as it gets. It’s open 24/7, always clean, and never overcrowded. The atmosphere is great. Everyone is friendly and follows proper gym etiquette. Their social media is a goldmine of useful fitness tips, and the music is always on point since members take turns curating the playlists. Easily one of the best gyms around.
