Heart Rate, VO2 Max, and Hunt Readiness with MTNtough
<p class="font-claude-response-body break-words whitespace-normal leading-[1.7]"><strong>EP 676 Heart Rate, VO2 Max, and Hunt Readiness with MTNtough<br />
</strong><br />
What’s up! This week on the Rich Outdoors Podcast, I’m sitting down with Jason and Nick from MTN Tough Fitness to talk about something we’ve been geeking out on for a while—health metrics, performance tracking, and what “hunt readiness” actually means for backcountry hunters.</p>
<p class="font-claude-response-body break-words whitespace-normal leading-[1.7]">As we’re building the Bridger Watch (yeah, the smartwatch for hunters), we’ve been having deep conversations with the MTN Tough crew about what metrics actually matter when you’re training for elk season. Because here’s the thing: most fitness wearables are built for runners, cyclists, and gym rats—not for hunters humping 60 pounds on their back through deadfall at 9,000 feet.</p>
<p class="font-claude-response-body break-words whitespace-normal leading-[1.7]">Nick is a MTN Tough coach and physical therapist who programs their daily workouts, and Jason is one of their athletes who’s joining the Bridger team. These guys know what it takes to train for the mountains, and more importantly, they understand the difference between sustained Zone 2 cardio and getting absolutely crushed by a 42-minute Mountain Tough workout that leaves you laying on the floor.</p>
<p class="font-claude-response-body break-words whitespace-normal leading-[1.7]">We dive into what a “hunt readiness score” could look like, how to measure work capacity beyond just heart rate, why rucking strain is completely different than cardiovascular strain, and how we can use wearables to help hunters stay in that 80-90% efficiency zone all day long. We also talk about the mental side of fitness—how to make better decisions under fatigue, why discipline in the gym translates to discipline in the mountains, and what happens when you’re on day two of a hunt with frozen boots and a broken water filter.</p>
<p class="font-claude-response-body break-words whitespace-normal leading-[1.7]">This episode is part fitness science, part backcountry hunting strategy, and part startup talk about building products that actually solve problems hunters face. Whether you’re training for September or just trying to figure out how to not get your butt kicked on your next western hunt, there’s a lot of good stuff in here. Let’s get into it.</p>

<h2 class="text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold">Three Key Takeaways</h2>
<ol class="[li_&]:mb-0 [li_&]:mt-1 [li_&]:gap-1 [&:not(:last-child)_ul]:pb-1 [&:not(:last-child)_ol]:pb-1 list-decimal flex flex-col gap-1 pl-8 mb-3">
<li class="whitespace-normal break-words pl-2"><strong>Heart Rate Monitoring Can Keep You in Your Efficiency Zone All Day</strong> – Most hunters blow themselves out on day one by pushing too hard when camp isn’t where they thought, or the trail is longer than expected. A wearable that monitors your heart rate and keeps you in an 80-90% efficiency zone (based on your current fitness level) could be the difference between being smoked for three days versus being able to hunt hard every single day. It’s not about going slow—it’s about understanding what pace your body can sustain without bonking.</li>
<li class="whitespace-normal break-words pl-2"><strong>Rucking Strain is Completely Different Than Cardiovascular Strain</strong> – Carrying 60-70 pounds on your back for 8 hours isn’t primarily a cardio challenge—it’s muscular, skeletal, and neurological strain. Most fitness wearables only measure cardiovascular load based on sustained heart rate, but they can’t quantify what it feels like to have weight on your frame all day. Building a “hunt readiness score” means figuring out how to measure both the cardio AND the strength components of backcountry hunting, which is why Mountain Tough’s blend of strength and conditioning is so effective.</li>
<li class="whitespace-normal break-words pl-2"><strong>Mental Toughness is Trainable Through Exposure to Hard Situations</strong> – The more you put yourself in challenging situations—whether that’s finishing brutal workouts when you want to quit, or waking up to frozen boots and pushing through anyway—the more you build the self-awareness and discipline to make good decisions under fatigue. It’s not about never wanting to quit; it’s about recognizing that thought, acknowledging it’s normal, and then choosing to push through. The fitness side removes one major stressor, so when other factors pop up (weather, wind, gear failure), you’re not also dealing with being physically smoked.</li>
