My story


My name is Haley Heit and I am an ACE Certified Personal Trainer and Functional Training Specialist. I am a Seattle native, growing up in the area and attending the University of Washington for my undergraduate degree. From windsurfing to soccer to skiing, I always enjoyed staying active throughout my life. In 2015, my husband Spencer and I uprooted our lives and moved to Maui, away from those we love most, to try and figure out what life is all about. Moving to an island that is so focused on health, well being and living actively drove us to start our personal training and guided hiking company, Adventure Built Fitness.

Moving back to Seattle, I have taken ownership of the company as Spencer pursues other opportunities and rebranded to H3 Fitness to represent my own personal brand. I am passionate about helping others achieve their goals so that can feel great doing the things they love most. I specialize in functional fitness, weight loss, boot camp and strength training.  I can’t wait to work with you!
