When one of Yumi’s favorite instructors (the incredible Chalene Johnson) told her that she should become a group fitness instructor because she was so inspirational, Yumi listened. It wasn’t long after that Yumi became a certified Group Fitness Instructor. Today at Mo-Mentum Fitness we are all grateful Yumi chose to share her passion with others because Yumi’s energy is contagious and transformational. Fitness changed Yumi’s life for the better.
