CSS Certified Indoor Cycling and Bootcamp Instructor

"I have always had a passion for fitness and working out. Cycling has always been the focal point and driving force behind my fitness goals, having competed in hundreds of mountain, track, road and currently cyclocross races. But I have found to be a good cyclist, it is important to train your whole body and challenge all the different muscles groups to achieve a strong core, cardio endurance and flexibility. The other key component is a strong mental capacity to push yourself to new heights and challenges. Having competed in Spartan races and other obstacle course events, has led to the
4-Alarm bootcamp class that is currently offered at CSS. Life is full of challenges, but if you keep yourself fit in both body and mind, those challenges become easier to navigate and confront.  
​As the saying goes, “Pain is temporary, quitting lasts forever.”

Olivia arena-miller

Certified Zumba Instructor

Yoga Loft Certified Yoga Instructor

"After attending free Zumba classes in a library basement, I knew that I wanted more Zumba in my life. In 2015 I got certified to teach Zumba. The combination of music, Latin dance,  cardio, and community struck a chord with me. 

I started my Yoga practice while studying at LCCC. I felt a deep connection to the philosophy behind the physical practice. I enjoyed the stretch that my body desperately needed, the workout, the breathing practices and the lessons of mindfulness. During the summer of 2017 I accomplished a personal goal as I completed my RYT 200 yoga teacher training. I’ve benefited from combining my passions for running and yoga. In doing so I’ve reduced tightness and the risk of injury. I’ve also found improved posture and a reduction in back pain. 

I am a firm believer that a physically active lifestyle and a whole foods and plant-based diet are key to a healthy, long life.
