Marie Gunther

Marie Gunther moved from the Netherlands to Los Angeles in 1990.

One day during a group fitness class I was encouraged to fill in for an instructor and this lead me to a new found career. I received my certification from ATAA for group fitness instructor ACE personal training and Indoor cycling through Johnny and Schwinn. Come join me for a cardio workout on a stationary bike based on cycling principles. My classes are based on technique focused cadence, climbs, along with 8 sprints; that can make an unpredictable ride that is both fun and challenging.
