Mark St. Arnaud, a competitive body builder, weight loss coach, personal trainer, and gym owner, developed the Fitin10 Challenge in 2016. Backed by 32 years of experience, Fitin10 is designed primarily as a fat loss program using sustainable and reasonable measures of exercise and diet. Mark wanted to demonstrate that you can make a great change to body composition without resorting to extreme methods.

“I would encourage people to look at Fitin10 as an opportunity to create lifelong habits for sustained change vs a quick fix”
