Jenny Marshall

Jenny Marshall

Jenny is a big part of the Total Body Works team and as a Massage Therapist she loves being able to help ease her clients pain. Now adding the Personal Training aspect to it she can help rebuild strength and mobility off of the table. She first started getting the desire to train when her son started to become an athlete and she learned the importance of strength training and athletic programing. Watching him improve and excel in BMX above and beyond any of his peers that weren’t training really opened her eyes to the benefits. She then started making goals and striving to achieve them for her own fitness, and the rest is history…

Jenny now has a desire to help anyone achieve physical fitness no matter what their age or ability level is. She believes that we are ALL created for greatness and that movement is life- if you don’t move, your quality of life will deteriorate. She is dedicated to helping you achieve your personal goals- whatever they are.

Outside of the gym Jenny enjoys spending time with family and friends, hiking, and serving at church.

Jenny lives in Colorado Springs with her husband John and 3 children Autumn Skye and Ryder.

Karli Davis

Karli comes to us with a background in strength and conditioning with certifications ranging from Athletic development, CrossFit level 1, Strongman, and USAW Olympic Weight Lifting. Karli has trained a variety of people ranging from professional and collegiate athletes to the general public.

And this is her story-

At the beginning of 2011, my grandmother, the most important person in my life, became very ill. As time passed, her body became weaker and weaker and it was becoming increasingly painful for her to move at all. I had to help her walk, sit, stand, and at the end, hold her as the nurses would change her sheets. One day, I saw a look of pure agony on her face while I was physically supporting her weight, I asked if I was hurting her, I knew I was, but she of course mustered up a smile and said “you’re doing great, honey.” In that moment, I vowed to get as physically strong as possible in order to help her never feel that pain ever again. Suddenly being strong, both physically and mentally, was no longer an option but a requirement. I saw first hand how life can throw curve balls at you, and it’s important and vital to take responsibility of your health, not only for yourself, but for those you love who may need you. That’s why I strive daily to be the strongest version of myself and hope to empower others to do the same.
