Sarah Jacobs

Sarah is a fitness enthusiast. As a former co- owner of a Wellness space, Sarah recognizes that fitness isn't a destination, and isn't based solely on physical exercise. It is a mindset, a community, and a method of self-care. The wellness journey is unique to each person and Sarah looks to connect with each person where they are each time they walk through the studio doors. Sarah focuses on form, anatomy, and pushing personal boundaries in her classes. She teaches with an encouraging, educational vibe centered on safe movement and progression. Sarah's classes include TRX with a strength- based flair, and Spinning, where the movement flows from the music. (Playlist requests entertained!)
