Flow Fitness is a locally-owned gym offering one membership for access to both its South Lake Union (SLU) and Fremont locations. It provides strong value with studio quality classes, training, and open gym access. The facilities are clean and well-maintained, with friendly and supportive staff. Members appreciate the variety, including high fit classes, yoga, Body Combat, indoor cycling, barre, HIIT, and standard gym equipment. Instructors are energetic and attentive, offering structured classes while allowing individuals to go at their own pace. The SLU location has a larger open gym space, while Fremont features larger group class rooms. Amenities include free lockers, towel service, cycling shoe rentals, free wifi, and free parking with a validation sticker. A key downside is that the gym, especially in SLU, can become extremely crowded during peak hours around 5-7 PM, which can sometimes impact workouts. Management is responsive to feedback, suggesting off-peak visits. The gym offers a one-week free trial and a new member special. It is widely recommended as a fun, clean, and friendly alternative to large chain gyms.
Love the gym, the variety of classes it offers and all the facilities. Loved Sarah’s barre classes :)

Jesson was amazing at LifeTime, and it saddens me that he's not there anymore, but bringing his talents to Flow is a BOON to the members here who are lucky enough to work with him, be INSPIRED by him, and hopefully, even learn from HIMMM
