Allison O “I have been taking Les Mills classes for over 6 years and was very excited to get the opportunity to instruct through our new RPM program a few years ago. The awesome instructors before me made it look so easy and I was surprised at how much of a challenge it was. I’ve since included BODYPUMP and I love every minute of it. Seeing the members smile when they talk about the results they are getting from my classes makes it all worth it. My husband and 2 girls have been very supportive and patient with my “hobby” and hopefully I’m passing on great habits to them. Most recently I have become certified in BODYVIVE as well.”

The members and staff make Fitness Revolution a place you want to be a part of, they give you the encouragement and drive to reach goals.

Now having been an instructor a little over a year, I find that my excitement has not diminished and that it is the team of instructors and members that keep it going. I only teach PUMP and COMBAT, I am a huge fan of the rest of the classes and can be found at the gym in what little spare time I have. The members have all become a family away from home for me and I feel lucky to be a part of such a positive and energizing group.”
