Holly Martin

Holly is a personal fitness trainer and professional contemporary ballet dancer in San Francisco, CA. Though originally from Northern Virginia, for her undergrad Holly chose Utah (go Utes!) for its renowned BFA Ballet Performance program. During her time there she discovered Utah’s unparalleled hiking and running trails, she had become an avid trail runner by the time she’d left. 

Holly’s latest pursuits in the personal training industry have been some of the most rewarding yet. She believes that anyone is capable of change. Self motivation and the ability to work hard  can be taught and procured with consistent direction and accountability. When she isn’t in rehearsal or performing, in the gym with or without her clients, she’s without a doubt running up any trail she can find…just as long as there’s a view of the Golden Gate Bridge 🙂 

Holly is always excited to meet and work with new athletes of all abilities! Shoot her a message if you’re in the Bay Area and looking to amp up your running 1-on-1!
