Hi! I'm Courtney. I was born and raised in Marin County, and now work in tech and teach reformer pilates at Bodyrok Studios. I was an athlete all my life, and I am a strong believer in finding movement that challenges you, but that you also enjoy! My goal is to inspire individuals of all different fitness levels to work hard and feel stronger, accomplished, and ready to take on whatever challenges they may face. I am all about good vibes, a killer playlist, and creating a space where working out is something that you get to do in your day rather than something you have to do.

So let's move! Whether you're just starting out on your fitness journey or a pro, I can't wait to move with you!
