    The Science of Aerobic Efficiency And How to Train It

    In this episode of the Athletes Compass podcast, the team breaks down aerobic efficiency—what it is, why it matters, and how it may be more important than VO2 max for long-term endurance performance. They explore the physiology behind efficiency, including mitochondrial development and capillary density, and explain practical ways to measure it using metrics like efficiency factor and aerobic decoupling. The conversation highlights the importance of low-intensity training, strength work, and recovery, while challenging the common “go hard all the time” mindset. The takeaway: slowing down and building a strong aerobic base is the key to unlocking sustainable speed and performance. Key TakeawaysAerobic efficiency = how much speed or power you produce per unit of oxygenImprovements come from mitochondrial growth, capillary density, and fiber-type adaptationsEfficiency Factor (EF) and Aerobic Decoupling are key metrics to track progressLower heart rate at the same pace/power = improved efficiencyZone 1–2 training is the most effective way to build aerobic efficiencyToo much high-intensity training can limit long-term progressStrength training improves efficiency by increasing force productionExternal stress (heat, altitude, life stress) can negatively impact efficiency metricsConsistency matters more than intensity spikesGains can happen at any age—but require patience and repetition Paul Warloski - Simple Endurance CoachingMarjaana Rakai | Nordic Performance Lab

    Menopause & Performance: What You Need to Know with Dr. Rebecca Robinson |

    In this episode of The Athletes Compass, Dr. Rebecca Robinson breaks down one of the most overlooked areas in endurance sports: women’s health across the lifespan, with a focus on perimenopause and menopause. Drawing from her experience as both a sports medicine physician and competitive marathoner, she explains how hormonal changes impact performance, recovery, and overall health—and why decline is not inevitable. The conversation covers fertility myths, training adaptations, nutrition strategies, strength training, and the importance of listening to your body. Ultimately, this episode reframes aging as an opportunity to evolve your training, not limit it. Key TakeawaysPerformance decline is not fixed—many women are peaking into their 40s and beyond.Overtraining and low energy availability can temporarily affect fertility, but long-term damage is unlikely.Estrogen plays a major role in bone health, cardiovascular protection, and recovery.Strength training becomes essential for maintaining muscle, bone density, and balance.Recovery, sleep, and fueling (especially carbs + protein) are more important than ever.Fasted training may increase stress and is generally not recommended for women.Hormone Replacement Therapy (HRT) should be individualized—not a blanket solution.Symptoms like fatigue, brain fog, and poor sleep can mimic overtraining.Listening to your body is the most powerful coaching and training tool.Enjoyment and community are critical for long-term athletic success.

    Move Better, Perform Better: Erin Carson’s Training Approach

    In this episode, Erin Carson, one of the most respected strength coaches in endurance sports, breaks down why movement quality is the foundation of performance, injury prevention, and long-term athletic success. She explains how many athletes are already “strong enough” but are limited by stiffness, poor mechanics, and inefficient movement patterns. From simple at-home routines to the concept of “easy speed,” Erin shares practical strategies to improve mobility, unlock better performance, and train for longevity, so you’re not just faster today, but still moving well decades from now. Key TakeawaysMovement quality = efficiency. Better movement reduces energy cost and improves performance quickly.Many athletes don’t need more strength—they need better mobility and coordination.“Easy speed” comes from improved mechanics, not just fitness gains.Tightness in the front of the body inhibits strength in the back (reciprocal inhibition).Most endurance athletes are overly tight in hip flexors and chest due to training posture.Overhead squats are a powerful diagnostic tool for mobility limitations.Ankles, hips, and thoracic spine are the three key mobility areas.Strength training should support movement, not compromise it.Small, consistent routines (“four things”) are more effective than complex programs.Multi-directional movement reduces injury risk and improves durability.Elastic energy (bounce) is more efficient than muscular force.Variety in training (especially for youth athletes) is critical for long-term success.Longevity training starts now: how you move today determines how you age.

    Rest Day vs. Recovery Day: What Actually Works?

    This episode explores one of the most debated topics in endurance training: whether athletes should take full rest days or train every day. Drawing from elite athlete examples and recent research, the hosts explain that there’s no single “correct” approach. Instead, recovery depends on training intensity, individual preferences, and lifestyle. They highlight the importance of low-intensity (zone 1) training, the role of the nervous system in recovery, and why many athletes sabotage progress by pushing too hard on easy days. Ultimately, recovery—whether active or complete—is a critical part of performance, not a break from it. Key TakeawaysThere is no universal rule: both daily training and scheduled rest days can work.Elite athletes follow vastly different recovery strategies—context matters.Active recovery (zone 1 movement) can enhance recovery through parasympathetic activation.Many athletes train “easy days” too hard, limiting adaptation.Zone 1 and Zone 2 training are crucial for building aerobic capacity and heart function.Full rest days are especially valuable when fatigued, sick, or mentally drained.Recovery is not just physical—it’s also mental and emotional.Walking, mobility work, and light movement are highly underrated recovery tools.Low-volume athletes may not need full rest days but should manage intensity carefully.Consistency and quality of sessions matter more than rigid schedules.

    HRV Training Explained: How to Know When to Push or Rest

    Heart rate variability (HRV) is transforming how endurance athletes approach training by providing real-time insight into recovery and readiness. Instead of following rigid training plans, HRV allows athletes to adapt workouts based on their nervous system state, leading to better performance gains and reduced risk of overtraining. This episode breaks down what HRV actually measures, how it reflects the balance between stress and recovery, and why factors like sleep, stress, and lifestyle play a major role. The discussion also explores practical strategies to improve HRV, when to adjust training intensity, and how to interpret low HRV without overreacting. Key TakeawaysHRV measures the variation between heartbeats and reflects nervous system balanceHigher HRV generally indicates better recovery and readiness to trainHRV-guided training leads to better performance gains than static plansPoor sleep is one of the biggest drivers of low HRVOne low HRV day → switch to aerobic trainingTwo consecutive low HRV days → consider full restChronic low HRV requires looking at the bigger picture (stress, hormones, lifestyle)Aerobic training is the most effective way to improve HRVStrength training is beneficial but should avoid training to exhaustionConsistency and context matter more than single HRV readings Why Your HRV Won’t Improve — Daily Reset to Boost RecoveryPaul Warloski - Simple Endurance CoachingMarjaana Rakai | Nordic Performance Lab

    Solo vs Group Training: Which One Is Better for You?

    In this episode of the Athletes Compass Podcast, the hosts explore the pros and cons of training alone versus training in a group. Recent research suggests that while both approaches can produce similar fitness outcomes, group training may lead to greater improvements in functional performance due to social support and motivation. The discussion highlights psychological drivers like self-efficacy, autonomy, and relatedness, and how they shape training success. The hosts share personal experiences with solo workouts, group sessions, and online communities, ultimately concluding that the optimal approach is often a balance tailored to an athlete’s personality, schedule, and goals. Key Episode TakeawaysBoth solo and group training work – overall fitness improvements can be similar across both approaches.Group training may enhance functional performance such as strength and flexibility due to social motivation.Psychological factors matter – social support boosts self-efficacy and self-regulation, which can improve performance.Autonomy vs relatedness – solo training supports independence, while group sessions provide connection and accountability.Training context matters – competitive athletes may benefit from focused solo sessions, while others thrive in social environments.Groups can push athletes beyond perceived limits, helping them discover untapped strength.Races often require solo resilience, making some independent training essential.A balanced approach (often around 80% solo / 20% group) can combine efficiency with motivation and social benefits.
