About this gym

Studio 45 is a Pacific Northwest boutique fitness studio built around a signature 45-minute, low-impact, high-intensity workout on Megaformer (and, in Kirkland, XFormer) equipment. Classes are capped at around 12 people for personalized attention, and the studio emphasizes a supportive, welcoming community alongside noticeable physical results in as few as 5 classes. The workout targets full-body strength, core stability, and cardiovascular endurance using counter-resistance movements that can burn 450-800 calories per session.
