Key takeaways

• Strength training should be a priority for aging endurance athletes, especially to preserve muscle mass and offset sarcopenia.
• Older athletes benefit from periodizing training so that strength and hypertrophy are emphasized farther from competition, with endurance-specific work increasing closer to the goal event.
• Zone 1 and Zone 2 work remain foundational, but strategic high-intensity work can help preserve top-end speed and fast-twitch fiber recruitment.
• Recovery may occur at similar physiological rates to younger athletes, but older athletes often feel more fatigued and need to respect that perception.
• Listening to your body becomes one of the most valuable skills with age, especially when deciding whether to reduce duration or intensity on a given day.
• Flexibility and mobility become increasingly important for performance and injury prevention, especially in areas like the hips, shoulders, and lower back.
• Protein intake matters more as athletes get older, with special emphasis on distributing protein throughout the day and supporting recovery after hard training.
• Leucine was highlighted as particularly useful for muscle repair and regeneration when paired with a strong training stimulus.
• Sleep remains the number one recovery strategy, supported by consistent habits and a cold, dark, quiet sleep environment.
• Excessive volume and too much sustained high-intensity or threshold work may increase cardiac risk in aging athletes, making moderation and recovery spacing more important.
• Training age matters: lifelong athletes, returning athletes, and late bloomers may all need different approaches.
• Staying motivated in older age often requires reframing success, adjusting expectations, and recognizing that every athlete in your age group is facing similar physiological changes

• 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.

In this episode of The Athletes Compass, the team sits down with Siren Seiler-Viken—researcher, coach, and emerging voice in Hyrox performance science. From her early years as an elite dancer to national-level distance running and now competitive Hyrox racing, Siren shares how sustainability, intelligent planning, and aerobic development form the foundation of hybrid performance. The conversation explores the physiological demands of Hyrox, why running may be the most overlooked performance driver, how to balance strength and endurance without sabotaging adaptation, and why pacing strategy can make or break your race. Whether you're a competitive athlete or new to hybrid fitness, this episode delivers practical, science-backed insight on building performance that lasts.

Key Episode Takeaways

1. Running accounts for ~60% (or more) of Hyrox race time — aerobic development is foundational.
2. Wall balls produce the highest physiological strain due to total-body demand + accumulated fatigue.
3. Hyrox is primarily an endurance event with strength elements—not the other way around.
4. Max strength matters—but mostly to raise your ceiling so race loads feel submaximal.
5. Muscle mass can become a liability if it compromises running economy.
6. A pyramidal or polarized endurance approach builds sustainable fitness.
7. Double-threshold training can be effective for advanced athletes when carefully structured.
8. Splitting strength and endurance sessions by 5–6 hours reduces interference effects.
9. Pacing is critical—early overexertion can derail the entire race.
10. Variation in endurance modalities (run, row, ski) supports durability and injury prevention.
11. Hyrox’s appeal lies in accessibility, inclusivity, and standardized global competition.

• Marjaana Rakai | Nordic Performance Lab

Key Takeaways

1. LT1 vs LT2: LT1 (aerobic threshold) = top of Zone 2, sustainable “all-day” effort. LT2 (second threshold) = highest sustainable steady-state effort before rapid fatigue.
2. Above LT2: Glycolytic demand increases, lactate accumulates faster, heart rate drifts, and fatigue accelerates.
3. Functional vs Lab Testing: FTP and critical power are practical field markers of LT2. Lab tests measure physiology, but field tests often matter more for performance.
4. Day-to-Day Variation Is Real: Sleep, fueling, equipment, environment, and training phase can significantly affect test results.
5. Base Training First: A strong aerobic base (mitochondrial development) improves tolerance to threshold work and increases fat oxidation capacity.
6. Over-Unders Work Because: They stimulate mitochondrial adaptations by forcing lactate clearance and improving aerobic durability.
7. Intensity Control Matters: Spending more time in the correct zone is more beneficial than constantly pushing the top end.
8. Most Common Mistake: Too much high-intensity work without sufficient aerobic base.
9. Durability Is the Goal: Threshold training should build resilience so performance doesn’t break down late in races.

Key Episode Takeaways

1. The Constrained Energy Model posits that daily energy expenditure plateaus, even with increased exercise.
2. Energy is redirected from "non-essential" functions like immunity and reproductive health under high training loads.
3. Over-relying on devices or formulas to track calories burned can lead to overfueling, weight gain, or gut issues.
4. RED-S (Relative Energy Deficiency in Sport) can impair hormones, recovery, and bone health, especially in female athletes.
5. Basal metabolic rate (BMR) forms the majority of energy use, but varies with sex, age, lean mass, and training history.
6. Fueling needs are individual: what works for Michael Phelps or Killian Jornet won’t work for everyone.
7. Tools like calorie counters can be helpful for education, but not as rigid frameworks.
8. Protein and strength training are critical, especially for perimenopausal women looking to protect bone and muscle mass.

Key Takeaways:

1. 30/30 intervals (30 seconds on, 30 seconds off) effectively recruit fast-twitch fibers and promote adaptations in both the cardiovascular and muscular systems.
2. These short intervals stimulate VO2 max while minimizing long-term fatigue compared to longer intervals.
3. Power output is higher during 30/30s than in 4x5 minute VO2 workouts, leading to better adaptations in well-trained athletes.
4. Recovery periods between intervals are key—passive recovery enables myoglobin resaturation and better performance.
5. 30/30s can benefit even Ironman athletes, despite the lack of specificity to long race paces.
6. Athlete type matters: “Diesel” athletes may prefer longer intervals; “twitchy” athletes often thrive with short ones.
7. Tools like Athletica’s workout reserve and power profile analysis help guide interval prescription.
8. Heart rate and power trends during sets can indicate whether an athlete is adapting well—or overreaching.

Key Episode Takeaways

• Race anxiety is normal—even beneficial. It's your sympathetic nervous system preparing you for peak performance.
• The amygdala triggers the fight-or-flight response, but emotions like anxiety can be short-lived if not mentally recycled.
• Preparation is your best defense: mental rehearsal, race plans, and pacing practice reduce unpredictability.
• Visualize the whole experience: from arriving in town to the final push—especially what to do if things go wrong.
• Human connection helps regulate cortisol: smiling, eye contact, and small interactions ease stress.
• Breathe to break the anxiety loop: techniques like box breathing calm the nervous system and restore focus.
• Self-efficacy is key: confidence from training and process goals reduces pressure on outcome.
• Reframe nerves as excitement and privilege: gratitude turns stress into motivation.

• Paul Warloski - Simple Endurance Coaching
• Marjaana Rakai - Tired Mom Runs - Where fitness meets motherhood.

Key Takeaways

• Mental performance is a skillset, not a personality trait or a feeling like motivation.
• “Ready” is a decision—you don’t have to feel ready to be ready.
• Athletes often underperform not due to fitness but because of emotional overload and mental unpreparedness.
• Motivation is unreliable—it fades when things get hard. Discipline is a decision.
• Physical discomfort is normal; learning to push through it (safely) is trainable.
• Performance blocks (like freezing or anxiety) are neurological disruptions, not signs of weakness.
• Language matters: Shift “I have to” to “I want to” to create a sense of choice and control.
• Fear of failure in youth athletes is often rooted in fear of looking like a beginner, not true failure.
• Emotions last 90 seconds—what prolongs them is rumination.
• Reframing isn’t toxic positivity—it’s productive thinking.

Key Takeaways

• Insulin is essential for moving glucose into muscle and fat cells but becomes problematic when chronically elevated.
• Advanced Glycation End Products (AGEs) from persistent high glucose contribute to aging and health decline.
• You can't outrun a bad diet—even fit athletes can become metabolically unhealthy with excessive sugar intake.
• Insulin sensitivity declines with age, high stress, or sugar-heavy diets, but can be reversed.
• Strength training and endurance training increase insulin sensitivity by increasing muscle mass and GLUT4 activity.
• Common signs of insulin resistance: stubborn fat, reduced performance, fatigue, poor sleep, and high blood pressure.
• Fasted training and reducing sugar can restore insulin sensitivity and boost fat metabolism.
• Lifestyle plays a huge role: stress and processed foods drive insulin resistance, especially in aging athletes.

• Paul Warloski - Simple Endurance Coaching
• Marjaana Rakai - Tired Mom Runs - Where fitness meets motherhood.

Key Takeaways

• Base training is critical: It builds aerobic capacity and sets the stage for effective high-intensity training later.
• Adaptation energy matters: Without a solid aerobic base, athletes struggle to respond to more intense sessions.
• Periodization isn't just for pros: Everyday athletes benefit from a structured plan tailored to their goals and life constraints.
• VO2 max work shouldn’t disappear during base phase—tapping into it year-round yields continued adaptation.
• Athletica allows for flexibility, letting athletes shift between base and build weeks depending on how they're feeling or recovering.
• Heart rate variability (HRV) can guide periodization, indicating readiness for harder work or a need to rest.
• Avoid over-racing: Always being in build or race mode leads to fatigue, poor performance, and mental burnout.
• Nutrition can be periodized too, aligning fueling strategies with session intensity to maximize benefits.

Key Episode Takeaways

• Strength training is essential—and beneficial—at any age, even into your 90s.
• Muscle strength ≠ maximal strength. Women don’t need to lift 1RMs to see progress.
• The common phrase “women are not small men” is often used to push shaky science.
• There’s no evidence to support that fasted training harms women; much of this fear is based on rodent studies.
• Women can build muscle across a range of rep schemes, not just with “lift heavy or fail.”
• Variation and personal preference are more important than rigid sex-specific protocols.
• Coaches must listen, adapt, and respect individual contexts—especially during menopause.
• Exercise doesn't need to be heroic; consistent daily movement wins over time.
