Katherine Markhauser

Founder of Chelsea Athletica & Certified Mat Pilates Instructor

Katherine Markhauser is passionate about creating spaces where women can move their bodies – whether through strength training or on their mats. Her work centers around building community and creating spaces where people can come together to move & meet like-minded people.

Her signature Burn class blends traditional Pilates with functional movement. The classes are designed to feel good in your body while still challenging you – combining compound movements into flowing sequences that sculpt the entire body with every rep, building strength while lengthening and toning muscles.
