Dustin Diefenderfer is the founder of MTNTOUGH, a digital fitness and nutrition coaching platform designed specifically for hunters and outdoor athletes. Since launching in 2015, his holistic approach combines cardiovascular endurance training for high-altitude environments, lower body strength and stability work for steep terrain, functional movements for carrying heavy loads, and mental toughness strategies for the unique psychological demands of backcountry hunting. In this conversation, Dustin reveals how he discovered that even highly fit CrossFit athletes weren't prepared for backcountry hunting, why most hunters focus on the wrong muscle groups when training, and the recovery strategies that matter most when you're miles from civilization with limited sleep and nutrition options.
What is MTNTOUGH and who is it designed for?
MTNTOUGH is a digital fitness and nutrition coaching platform that provides practical training routines designed to prepare hunters and outdoor athletes for the unique physical demands of backcountry hunting, high-altitude pursuits, and wilderness adventures. The platform focuses on cardiovascular endurance at elevation, lower body strength and stability, carrying capacity, mental toughness, recovery strategies, and a holistic approach to health that includes nutrition, sleep, and stress management.
Who is Dustin Diefenderfer?
Dustin Diefenderfer is the founder of MTNTOUGH and a former strength and conditioning coach who worked with athletes in the CrossFit space. Growing up in Colorado as a lifelong hunter, he recognized that traditional fitness programs weren't preparing athletes for the demands of backcountry hunting, which led him to create MTNTOUGH in 2015 with programming specifically tailored to hunting and outdoor pursuits.

From CrossFit Coach to Founder: The Origin of MTNTOUGH
Dustin's path to creating MTNTOUGH came from a critical observation while working as a strength and conditioning coach in the CrossFit world. Despite training athletes who were exceptionally fit by conventional standards, he noticed a glaring gap when those same athletes headed into the backcountry. The movements, energy systems, and mental demands of hunting required something entirely different than what traditional fitness programs provided. Growing up hunting in Colorado gave Dustin firsthand experience with what the mountains actually demand from your body, and he realized there was no training resource specifically designed for this unique athletic pursuit. That realization sparked the creation of a platform that would bridge the gap between general fitness and mountain-ready performance. Dustin explains how MTNTOUGH was born from this gap in the fitness industry starting around the 1:30 mark.
The Four Physical Demands That Separate Hunting From Other Sports
When Dustin breaks down what makes hunting unique from an athletic standpoint, he identifies four specific physical demands that most fitness programs completely miss. First is cardiovascular endurance in high-altitude environments where oxygen is limited and every step requires more from your system. Second is lower body strength and stability for navigating steep, uneven terrain where a single misstep can end your hunt or worse. Third is carrying capacity—the ability to haul heavy loads whether it's your gear going in or a harvested animal coming out. And fourth is mental toughness and resilience to handle extended periods of waiting, harsh weather conditions, and the psychological challenge of navigating remote terrain. What's interesting is how these demands stack on top of each other, creating a compound effect that standard gym training simply doesn't address. The breakdown of these four specific demands starts at 4:13.

The Holistic Approach: Why Physical Training Is Only One Piece
What separates MTNTOUGH from conventional training programs is the holistic framework that considers physical fitness as just one component of total performance. Dustin emphasizes that nutrition, recovery, sleep quality, stress management, and overall lifestyle all work together to determine how you'll perform in the field. Ignore one area and it creates a cascade effect that undermines everything else. The platform provides resources on mental resilience, visualization techniques, goal setting, and dealing with failure—because hunting involves far more setbacks than successes. There's also deep focus on nutrition timing, hydration strategies for dry high-altitude environments, and recovery protocols that work both at home and in the backcountry where conditions are far from ideal. The community aspect creates connection among hunters and outdoor athletes who understand the unique challenges of training for pursuits that don't fit traditional sports categories. Dustin's explanation of the holistic approach and why every component matters starts at 3:42.

SubscribeThe Four Biggest Mistakes Hunters Make When Getting Fit
Through years of working with hunters of all experience levels, Dustin has identified four common mistakes that undermine training efforts. First is doing too much too soon, which leads to either injury or burnout before hunting season even arrives. Second is focusing too heavily on upper body strength when the real demands are in the lower body and cardiovascular system. Third is ignoring recovery and subscribing to the "more is always better" mentality that actually prevents adaptation and increases injury risk. And fourth is neglecting the mental side of preparation—hunters spend so much time on physical readiness that they forget hunting is equally a mental game requiring psychological preparation for long waits, missed opportunities, and challenging conditions. The assessment process that MTNTOUGH uses helps identify where each individual athlete is starting from, any injuries or limitations they're dealing with, and what their specific goals are so programming can be personalized rather than generic. The four biggest training mistakes hunters make are detailed starting at 10:00.

Key Takeaways
- MTNTOUGH was born from recognizing that even highly fit CrossFit athletes weren't prepared for the specific demands of backcountry hunting, creating a gap in the fitness industry that needed filling.
- The four physical demands that separate hunting from other sports are cardiovascular endurance at altitude, lower body strength and stability for steep terrain, carrying capacity for heavy loads, and mental toughness for extended challenges.
- Most hunters make the mistake of focusing too much on upper body strength when they should prioritize lower body and cardiovascular training for mountain performance.
- The holistic approach considers physical training, nutrition, sleep, recovery, stress management, and mental toughness as interconnected components—neglecting one undermines all the others.
- Recovery in the backcountry looks completely different than at home, requiring strategies for maximizing limited sleep, managing nutrition constraints, and staying mentally sharp in challenging environments.
- Training timelines depend on current fitness level—beginners need 3 to 6 months of preparation while already-fit athletes might only need 6 to 8 weeks before hunting season.
- The principles of training for hunting transfer to other outdoor pursuits like backcountry skiing and mountaineering, though programming is tailored to each activity's specific demands.
Final Thoughts from Tom
What strikes me most about Dustin's approach is how it mirrors what we talk about constantly in fishing—the need for holistic preparation rather than just technical skill. You can have all the right gear and know every tactic, but if your body and mind aren't prepared for the physical demands and mental challenges, you're starting from behind. The four specific demands Dustin outlines for hunting—altitude endurance, lower body strength, carrying capacity, and mental toughness—translate directly to long days on the water, navigating boats in rough conditions, and maintaining focus during slow periods.
I also appreciate his honesty about the mistakes hunters make when training. The tendency to do too much too soon and focus on the wrong muscle groups is something I see constantly in fishing preparation. And his point about recovery being just as important as the work itself is something we don't talk about enough in the outdoor space. Whether you're training for a backcountry hunt or preparing for a week offshore, the principles are the same.
If you're serious about outdoor pursuits—whether that's hunting, fishing, or any other adventure that demands physical and mental preparation—this conversation is worth your time. Dustin lays out a framework that applies across disciplines, and his holistic approach is exactly what outdoor athletes need to hear.
