Everything You Need, All in One Place

Flow Fitness South Lake Union brings together boutique studio classes and a complete gym at a single location. If you love studio classes, you'll get nearly 60 classes per week across yoga, barre, and fitness formats—plus full gym access whenever you want it. If you're serious about strength training, you'll appreciate a well-equipped open gym with plenty of space and equipment.

You're not locked into one workout style. Your fitness routine can shift with your goals, your schedule, and your motivations. That's the freedom you get at Flow.

One Membership.
Zero Compromises.

Walk into our South Lake Union location and you'll see what makes us different. A massive yoga and dance studio filled with natural light. A fitness studio built for high-energy group classes. And a functional training area designed for serious work, not an afterthought squeezed into a corner.

The open gym gives you full dumbbell sets, cable systems, and room to move without waiting in line or working around someone else's superset. After your workout, unwind in the dry sauna. Whether you're flowing through vinyasa or loading up a barbell, you'll have the space and equipment to do it right.
