Renee Oleson

What I teach: Barre
Bio: Renee, a lifelong dancer and coach, started her fitness career in 2009 by obtaining her ACE Personal Trainer, Spinning and Freemotion Indoor Cycles certifications. She was fortunate to fall in love with the music-driven & choreography-based isometric barre movements as a teacher and manager of Pure Barre studios and is thrilled to continue her passion for Barre with Endorphin! Renee loves finding new challenges in a controlled and safe environment. Growth comes from change and trying new things while avoiding injury - so that you can come back tomorrow! Choose the hardest variation of an exercise that you can HOLD GOOD FORM and go from there. Everyday will be different - she pulls inspiration for classes from the previously mentioned modalities as well as from her days as a Zumba cardio dance and Water Aerobics teacher - but the bottom line is to have fun and be kind with yourself!
