MTNTOUGH Fitness Lab was born out of a desire to prepare backcountry hunters for the demands of high elevation, and weeks-long trips under heavy load in the world’s most remote locations. In their Bozeman R&D facility they know superior physical fitness is crucial for success, but more important is teaching their athletes how to be “comfortable being uncomfortable”. This focus on the mind and mental toughness quickly crossed over with application to the elite military, and first responder athletes they train. MTNTOUGH is a constant state of evolution, as they believe there is much more to learn about human potential, and they develop this mental toughness in many ways.
“ONE THING THAT WE DO IS TEACH MTNTOUGH’ERS HOW TO TURN THE EXTRAORDINARY INTO THE ORDINARY. EXTRAORDINARY EVENTS WITH ACTION CAN BECOME QUITE DOABLE, THEN WITH CONTINUED DEDICATION THEY BECOME ORDINARY, ONCE THEY FEEL ORDINARY YOU HAVE TURNED A CEILING INTO A FLOOR AND GAINED MENTAL TOUGHNESS.” EXPLAINS MTNTOUGH’S DUSTIN DIEFENDERFER.
This week’s workout marking the final set in our series with MTNTOUGH is called “The Devil’s 55.” If you could only do one workout with limited equipment this would be at the top of the list. It is 55 minutes of total-body work, making it an extraordinary challenge to finish, but with continued dedication this can become an ordinary workout you can do anytime, anywhere with only a weighted pack.
