Erin Ambler has been working in the fitness industry for over 2 decades. Through the years, Erin has managed various gyms, big and small, and has helped countless clients achieve their fitness goals through group couching / personal training. For Erin, It was an easy decision to join the team at F45 as the culture of the facility emulates a wonderful sense of community. In addition to fitness training, Erin loves to remain outside where she can participate in many outdoor activities including hiking, snowshoeing and zip lining. However, dancing and music resides at the top of her list. She hopes to eternally remain active and strongly believes in the importance of maintaining physical strength for the sake of quality of life. You might even hear her utter, “TRAIN inside so you can PLAY outside,” from time to time.
