Favorite Part of Training I have been part of 9Round since I was 18. I love that I can now help people in the same way 9Round helped me for all these years!
Hi! My name is Megan and I've been part of the 9Round team since October, and I absolutely love the community we've built- where we all show up with shared goals and support each other, even through the challenge of birthday burpees! When I'm not at the gym, you'll usually find me on a road trip, exploring a local coffee shop, or getting lost in a good book. I share my adventures with my two dogs, Mini and Kona, who keep life fun and full of energy!
