Meet JIM 

O’Brien, Kaitlyn and Melanie founded JIM on the basis of functional movement, utilizing your body as your method to achieve optimal fitness with minimal equipment. JIM’s founders believe in the principles of working within a team as a foundation for success and personal growth. Motivation through your peers, and working together as a community towards a common goal of self-improvement is what sets JIM apart from other fitness facilities.

Located in the historic Park Mercantile Building in Columbia Falls Montana, JIM is a fusion of rustic architecture, original exposed brick, raw wood and clean finishes.  Twenty-foot ceilings cultivate acoustics to amplify motivational music to power you through your toughest workouts. JIM’s expansive original wood floors provide a workout area unparalleled to others giving way for dance, circuit training, station work, T.R.X. Suspension Training, speed and agility work, barre and pilates.  

Nestled in the heart of Columbia Falls, Montana, JIM is open six days a week, Monday-Friday 6:00 a.m. - 1p.m. Monday- Thursday 4p.m.-7p.m. and Saturday's 8 a.m.- 11a.m.
