Lauren Gill
CrossFit Coach
Lauren first discovered CrossFit in 2015 after walking by her local gym daily to and from work in NYC. It took only one class, and she was hooked on the challenge of the workouts and the community.
MORE ABOUT LAUREN
After playing soccer for 15+ years, she missed the camaraderie and the competitive side of the sport but found it again within CrossFit. She believes in supporting athletes to be the best versions of themselves and pushing them to “that dark place” during workouts. Lauren has coached in NYC and Philadelphia and is currently in Denver at 720.

Summer Henderson
CrossFit Coach
Summer found CrossFit back in May of 2016 while she was coaching group fitness classes at the CSU recreation center.
MORE ABOUT SUMMER
Many people had told her she would like it, and she always thought it was way too badass for her, but she still decided to try out a local box nearby. It didn’t take long for her to realize how much she loved it and how it is for all fitness levels. She jumped at the opportunity to coach and found it very rewarding to coach others through their personal health journey while still working on her own.
