5 Best Gyms in Seattle (2026)

Transform 180 Fitness has been coaching in Seattle since 2012 and now runs three open locations (South Lake Union, Belltown, Madison Park) with a fourth on the way in Bellevue. The gym is built around 24/7 keyless entry via the Kisi app, alongside 1:1 and partner personal-training formats. Facilities include commercial-grade equipment from Hammer Strength, Technogym, Rogue and Eleiko, plus showers, sauna at two locations, and free parking. It's a training-first gym rather than a big-box chain, with a small roster of named coaches members come back for.

RowdyBox is a boxing-inspired fitness studio in Belltown that blends boxing rounds with strength training in its signature Box x Lift classes. The studio positions itself around community and energy as much as the workout itself, with a roster of named coaches running the floor. It's a class-based model rather than open-gym access, aimed at people who want structure and a group to show up for.

Rain City Fit runs an 18,000-square-foot facility on 11th Avenue between Pike and Pine, open 4am to midnight daily. The space includes multiple floors, a full cardio and strength lineup (Rogue squat racks, Cybex machines, Concept2 rowers), nine gender-neutral bathrooms with showers, and even a tattoo shop and salon on-site. Membership runs $69 a month with no contract and no signup fee, and pricing is fully transparent on their website.

Cap Hill Fitness is an independently owned gym with two locations a few minutes apart in the heart of Capitol Hill. Owner Clinton runs the place hands-on, and the gym focuses on clean, well-maintained equipment rather than extras. It's positioned as an accessible, community-first alternative to the bigger commercial gyms nearby.

Henry's Gymnasium occupies a historic building on Boylston Avenue with a distinctive three-floor layout: a lower level built for lifting, a middle floor focused on recovery, and an upper floor for cardio and cable work. The gym leans into its architecture and decor, with curated art, mood lighting, and an on-site bar serving pre and post-workout drinks. Premium Gym80 equipment fills the space alongside more standard strength gear.
