Mark became active within the fitness field at a very early age. In an effort to increase his knowledge and skills, he studied sports management at the University of Texas and took a position in their athletics department.
In building upon his mission to change the way the world exercises one client at the time, Mark founded Efficient Exercise in 2001. In 2009, Mark teamed up with inventor Randy Rindfleisch to develop ARx (adaptive resistance exercise) technology. In 2011, he joined with Keith & Michelle Norris as an original founder & owner of Paleo f(x)™.
