My name is Mila Clauss. I currently live in Ellicottville with my husband, Trey, and our little boy, Trennon. As a kid/teenager I was never “active”. I was not involved in organized sports; my interests seemed to lead me toward more creative outlets. It was in my early 20s that I realized (or rather accepted) that I was overweight, out of shape, and the “Freshman 15” hadn’t done much for me. In 2006, I had just started my career as a teacher in Springville when another colleague suggested we join the local gym. That’s when fitness and Kim Duke first entered my life. I remember walking into the gym to take my first class and halfway through the class I walked out because I literally thought I was going to faint. I persisted though, returning for classes, and eventually hiring Kim as a personal trainer. At that time, I was the person who consistently thought (and asked Kim), “How long will this take”, “When can I be done working out”, and “Is this the final set forever”. Needless to say, I didn’t see the results I was looking for. I dropped in and out of classes and training and started and stopped many diets. It was not until January 2010 when I broke my leg while skiing that I made the change I had needed for so long. After surgery the doctor told me I would be unable to walk on my right leg for 5 months. This “sentence” literally kick started my journey to NEVER being lazy and unmotivated again. I rehabbed my leg through physical therapy and started training with Kim (again) about 2 months after the injury. I began to eat healthy and started to see the results. This time around it wasn’t about “how long” or “when can I stop”; it was about “what’s next” and “when can I workout again”! At the end of those 5 months I was the healthiest, leanest, and strongest I had ever been in my entire life. From there I wanted to keep up my fitness level and healthy lifestyle so I took courses to become a group fitness instructor, which is where I am today. Being fit and active is something that is part of my everyday life. It took a long time for me to realize that fitness and health aren’t short-term goals, but something I can enjoy and do everyday. Changing up my fitness routine, enjoying the things I like (not being “stuck” on a diet), and surrounding myself with like-minded people who motivate and encourage me keep me going each and every day. Besides having our sweet, baby boy and marrying my best friend, getting fit has been one of my biggest accomplishments. I am firm believer that “you are one workout away from a good mood”!

I fell in love with Zumba 5 years ago and never looked back! When I lived in Buffalo I was taking classes twice a week and having so much fun. When I moved to Ellicottville, I wasn’t sure where to go. I tried a few places out, but had to drive 20-30 minutes away to go to class! Finally in March I decided to take the certification and just teach Zumba myself!! I wouldn’t have to drive anywhere and I could share my love of Zumba with everyone!

Working out doesn’t have to be a chore, it should be fun! We like to call Zumba, “Exercise in Disguise”. In fact, my Zumba class won’t feel like exercise at all, it will feel more like a dance party with your new Zumba sisters. No experience is necessary and everyone can join in on the fun!
Ditch the workout and Join the party!! My Zumba class is guaranteed to make you sweat and smile!
