MJ Fit

Empowering women to be strong and confident

Reaching heights and goals you never thought possible

My name is Marshelle and I am one of the many transplants who has chosen colorful Colorado to be my forever home! I grew up in a small farming community in Missouri and because I was a competitive dancer and always at practice, I never had to think about exercising or what I ate until I graduated high school and began my freshman year of college. During this time, I struggled with self-esteem and developing regular exercise and diet routines to aid me in losing the “freshman 15″ (and then some) I had gained. After a year of this, I moved to Boston to try to figure out who I was and what I was meant to do.

My journey to health and loving life really began with this move. I struggled at first and actually got dangerously thin, but once I began educating myself on what a “healthy” lifestyle really is and how it should make you feel, I was hooked. Soon after I moved, I signed up through California University of Pennsylvania to get my B.S. in Sports Management. At nearly the same time, I set a date for a WNBF bikini bodybuilding show. I have since graduated from CALU with presidential honors, and have competed in five bodybuilding shows and four powerlifting meets as a natural athlete.

After a year of working as a trainer at the Boston YMCA, I took a job as a personal trainer at a highly-regarded, exclusively-female gym in Back Bay, Boston which is where I discovered my passion for working with women. I had the pleasure of working with diverse, strong, and incredible ladies–many of whom I still work with today through my online training program.

Through the changes I have seen in myself and those of my clients, I can see there is a great need for the kind of supportive and empowering environment MJ Fit offers to Colorado’s women fitness community.
