Karie Kerner

Woman-owned: Karie came in as Glen Marshman’s client, spent two decades on this floor, and now owns the place. Still training members most days.

NASM CPT · Feldenkrais

Over the past 20 years, Karie has had the pleasure to personally train and work as a trainer at One Boulder Fitness. Now, with great pride, she is one of the owners of "the sweet club." As an opera singer, she studied and trained with previous One Boulder Fitness owner, Glen Marshman, a former body builder. Through her love of training and teaching, she finds an immense joy from the learning that happens not only for herself, but for her clients. "A tremendous gift!" Being a trainer on the floor 30+ hours a week, she feels that as a teacher/trainer, it is her job to help her students/clients find awareness and repair those athletic/physical expressions that have "lost their creativity." To achieve this, Karie believes strongly in moving and loading your muscles with ease, keeping the mind/body connection strong and learning to foster those creative pathways through all planes of movement. "We are our own wisest master."
