Multi-Studio Boutique Health Club


There is a growing trend, especially among millennials, to join a multi-studio boutique health club in South Lake Union that provides so much more than the common one-size-fits-all traditional gyms.

Rather than an open floor plan with numerous machines and mirrors, our unique health club in South Lake Union provides individual studios for:

  • Cardio and cycle sessions
  • Weight and strength training
  • Barre and yoga classes

Our members prefer our methods that focus on individual goals, positive health and physical results in a comfortable environment that celebrates their successes.  Rather than training that focuses on intimidation, we deliver value based on motivation by a staff that is knowledgeable in health and wellness, utilizing discipline-specific training methods that employ science behind the exercises.

Call Flow Fitness to learn why our members choose our facilities to meet their goals rather than using common cookie-cutter exercises that do not suitably support them.  Or, if you would like to see firsthand what makes us so unique, schedule a tour today by calling 206-621-7246!
