Olivia Ottinger

My name is Olivia! I have a B.S. in Kinesiology, specializing in physical rehab. My professional background is in both, recreational fitness and physical therapy. Personally, my fitness journey started in athletics, but has since evolved into powerlifting and bodybuilding. But my passion for fitness isn’t limited to the gym, I love outdoor recreation, and really any kind of physical activity. I have experience with clients whose goals vary from competition prep, to lifestyle change and weight loss. I also have experience with clients interested in addressing a nagging injury through exercise rehab. My goal as a trainer is to educate my clients, build better habits, and ultimately enhance their confidence. I’d love to get to know you, and share my passion!

I’m an extremely enthusiastic person who gets excited by any success, wether it’s big or small. I’m a devoted Wife and Bonus mom, so I know what it is like to become wrapped up in day to day life that you forget your name and who you are. That being said, I absolutely LOVE helping clients find themselves and watching their confidence grow. I see so much potential in everyone and just want to help you be the best version of you! I currently have 6 certifications, 3 NASM which are CPT, group exercise, and nutrition. I have my ACE CPT. Kettlebell 1 & 2, and TRX certification. I do have a Zumba certification. However, other than me dancing in excitement every time we nail a milestone, those days are behind me! I’ve been apart of the big jon fitness family since 2015. I have my own story and journey with Big Jon. I started gaining weight, I was in denial. It seemed like it came on so fast. I didn’t know what to do; I actually gave up. I knew i couldn’t do it alone and wanted help. With Big Jon’s guidance and support, I lost over 50 lbs and learned how to make the right choices and live a healthy lifestyle! I’m a firm believer that accountability and the right knowledge is the difference maker! This lifestyle is possible for anyone. It is all about taking time to make it a habit and learning your own strength and weaknesses. Just remember you totally can do this!
