After a helicopter accident while serving in Afghanistan in 2012, U.S. Marine Corps Veteran and iFIT Trainer Kirstie Ennis lost her left leg and was forced into medical retirement. Despite her struggles, Kirstie wanted to find another way to continue serving people.
Reflecting on when she first adapted to life on one leg, Kirstie knew she wanted to inspire others to not allow their circumstances to control them. Since the accident, she’s become a competitive para-athlete, public speaker, Hollywood stuntwoman, and mountaineer, to name a few of her accolades. Now, Kirstie works with a variety of organizations, including the Kirstie Ennis Foundation, to help improve the quality of life for others through mobility, education, and healing in the outdoors. She continues to push boundaries today with her mission to tackle the Seven Summits on one leg by 2021.

In 2012, I was severely injured in Afghanistan while serving as a helicopter door gunner in the Marine Corps. As a result of the helicopter crash, I sustained a traumatic brain injury, trauma to my cervical spine, damage to my arms, ears, and eyes, and breaks to my leg that would later result in a below-knee amputation. Over time, my limb got worse and due to complications, I became an above-the-knee amputee in 2015.
The easiest way to explain the recovery process of an amputee is it’s never-ending and, quite frankly, it's like being a toddler all over again. First learning how to balance, then walk, move on uneven terrain, and eventually run. However, all too often it's like taking one step forward and two steps back. Since 2015, I’ve had three other revisions to my residual limb that have required learning it all over again.
All too often, people see me and think that losing my limb was the hardest part. However, it's really the invisible injuries that have been the hardest to overcome because of all of the unseen emotions and internal battles. Brain injuries and PTSD require a lot of attention and have unique learning curves, but physical injuries leave a lot of emotional pain too—such as grief and survivor’s guilt.
It's the six inches between our ears and what's behind our ribcages that determine what we are capable of. If we keep our heads and hearts in the right place, we can overcome anything.

A nonprofit walked into my hospital room at a time that I would've done anything to get out of it. They offered to teach me how to do a winter sport. Even though I’m originally from Florida, I jumped at the opportunity. When I arrived in Breckenridge, Colorado and no one asked me for a medical clearance, I decided that I wanted to learn to snowboard because it looked the “coolest.” Then, the rest was history. It was a solid reminder of my resiliency and that I could still be independent regardless of what my injuries were. No one else could get me down that mountain.
I stopped competing in 2016 after I had another setback of a surgery, but I still needed something to keep myself focused and setting goals. I decided that I was going to climb Kilimanjaro in March of 2017 (not sure my doctors would be happy to hear about that). I managed to climb up and down the mountain in four and a half days. That’s when I realized I was strong and stubborn enough to be a good mountaineer.
The best part was the team I climbed with raised nearly $150,000 for clean water for the East Tanzanians. That's when I decided that I would use mountaineering as an opportunity to continue as an athlete while having a means to still be of service to others.
Summiting Denali this year was an insanely emotional experience. It was a reattempt after having to turn around in 2018. As we went over the summit ridge, it was overwhelming. Hands down, it was one of the hardest things I’ve ever done physically or emotionally. I was humbled, yet so proud of my team. I cried several times while standing up there.

Surviving my darkest days and living to be a role model to the next generation.
The next generation. The kids who need hope, the men and women needing inspiration, and the non-believers waiting for me to prove them wrong. My “why” is about all of the people around me and leaving a legacy that shows we don’t have to let one chapter of our lives determine the rest of the story. An injury, setback, or failure does not define us.

To relax: Italy. To climb and explore: the Himalayas.
I am a serial entrepreneur, having owned and sold several businesses from a variety of industries. Currently, my main focuses are a brewery, whiskey company, speakeasy, and apparel company. I also have three master’s degrees and am in my last year of a doctorate.
