Medical exercise specialist, fitness coach/trainer and author Cinder Ernst recently moved to Napa to expand her business. 

Ernst began her career as a personal trainer almost 30 years ago in San Francisco. Ernst founded the one-on-one training program at the San Francisco Central YMCA in 1989.

In 1989, Ernst also pioneered the concept of weight- neutral fitness programming for plus-size women. In 2017, Ernst published her latest book, “Easy Fitness for the Reluctant Exerciser."

Ernst will offer free Easy Fitness Knee workshops and fitness classes. The first will be held at the Napa Library on Saturday, March 24 at 2 p.m.
