" I want to be able to have one hour, one workout, and be on my way with my day. That's what I've been able to find with Get Kristen Fit."

“I am so happy I stumbled upon GKF because I would have not made it through quarantine without Kristen and the community. The classes push me and work muscles I didn't know I had. They are fun, but most importantly I love the people a part of GFK. I look forward to "seeing" my new friends online or at the track for some butt kicking.”

“Get Kristen Fit doesn’t give you an opportunity to doubt yourself during her intense workouts. She knows when you think you can’t and instinctually mentally pushes us through with nothing less than a ‘can’ attitude. I am so appreciative of GKF and her ability to design programs based on my specific needs but yet coaches me through her group workouts with ease (and A LOT of sweat).”

“Get Kristen Fit’s workouts are my favorite ! They make me feel like the 8 year old girl who LOVED sports and preferred playing with the boys. By the age of 10 I was told I was ‘too much’ , and ‘I should settle down and take ballet lessons and ‘be a lady’. I was told to be a cheerleader rather than play basketball. The thing that has helped me the most to reconnect with that 8 year old is to be treated like a genuine athlete. I can’t thank Get Kristen Fit enough. Sometimes your body knows what your head doesn’t and you just have to start in the body first. <3 .”

"Kristen understands bodies of all shapes and ages. I am a 56 year-old woman who experienced knee surgery in January and began training and taking GKF classes in March. Six months later, my body is better than it was on my wedding day 30 years ago! My form is better and I am stronger. Through these uncertain times, Kristen has created a community of women who lift one another up. I look forward to being a member of the GKF family well into my 80s"

Results Driven Fitness

Move Better.  Feel Better.  Spend More Time LIVING!

GKF In Studio Experience

GKF Online Studio workouts are designed to bring us "together" in experiencing the GKF method of training. Not only will you get stronger, improve your overall fitness, and increase lean muscle mass.....but you WILL be taught how to properly perform and progress each exercise! There are no other group fitness CLASSES out there that can make you sweat this much all while training you for longevity and a lifetime of fitness without injury. GKF workout Programs change monthly to progress you through different stages of building muscle, losing fat, building endurance, building work capacity, and developing functional movement patterns.  It’s like custom personalized training but with the motivational class atmosphere.  GKF classes are designed for you to workout 3-6 days per week for about 1 hour. You can always modify to meet your needs and schedule.
