How to Exercise for Strength Gains & Hormone Optimization | Dr. Duncan French

Episode 45 Nov 8, 2021 1h 28m 25 insights
In this episode, I talk to Dr. Duncan French, Ph.D., the Vice President of Performance at the UFC Performance Institute and a world-class performance specialist. We discuss specific resistance (weight) training regimens for increasing testosterone in men and women and how to vary mechanical loads and rest between sets and workouts to optimize hormone output and training results. We also discuss how stress-induced "catecholamines" can increase testosterone or decrease it, depending on duration and mindset. And we discuss specific cold- and heat- therapies for increasing resilience, reducing inflammation, heat shock proteins and more. We discuss nutrition for training and how to match nutrition to training goals and metabolic flexibility. We discuss mental focus and how long to train for skill development. Finally, we discuss how mixed martial arts and the UFC Performance Institute are a template for exploring human performance more generally. This episode is intended for anyone interested in athletic and mental performance: athletes, students, and recreational exercisers and includes both science and many practical tools people can apply in their own training.  Read the full show notes for this episode at hubermanlab.com.
Actionable Insights

1. Optimize Resistance Training for Anabolism

To maximize anabolic environments and muscle growth, perform resistance training with six sets of ten repetitions at about 80% of your one-repetition max, ensuring two minutes of rest between sets to drive metabolic stimulus. Adjust loads to sustain 10 repetitions per set.

2. Needs-Based Eating for Training

Practice needs-based eating by timing carbohydrate intake strategically around training sessions (pre, during, immediately post) to fuel high-intensity efforts. Maintain a largely reduced carbohydrate diet for the rest of the day to promote metabolic efficiency.

3. Implement Heat Acclimation Protocol

To improve heat tolerance and sweat rates, begin with 15 minutes of sauna exposure (around 200°F) and gradually increase to 30-45 minutes continuously. Aim for about 14 exposures over 8-10 weeks for significant adaptation.

4. Strategic Cold Exposure for Recovery

Use cold exposure strategically: avoid it during periods of high training load focused on muscle growth, as it can hinder hypertrophy and strength adaptations by dampening the mTOR pathway.

5. Quality Over Quantity in Skill Learning

For physical skill development, prioritize quality over quantity by keeping sessions shorter and stopping when fatigue impacts movement accuracy. This ensures the rehearsal of correct movement mechanics.

6. Embrace Adaptation-Led Programming

Adopt an ‘adaptation-led programming’ mindset, understanding that the body is highly plastic and will adapt to specific stimuli. Consciously change overload and stimulus across all training, nutrition, and recovery aspects to drive desired adaptations.

7. Be a Self-Aware Athlete

Become a ’thinking man’s athlete’ by consciously understanding your body’s state at all times. Use subjective feedback (mood, sleep, feelings) and objective training logs to interpret individual responses and optimize performance.

8. Master State Toggling

Develop the ability to toggle effectively between high-alert, focused states and calm, relaxed states. This skill is crucial for managing energy, preventing burnout, and sustaining high-quality performance over extended periods.

9. Leverage Acute Stress for Performance

Embrace and leverage acute stress, such as pre-workout arousal or anticipation of a challenging event, as it can increase testosterone and sympathetic arousal (epinephrine/adrenaline), leading to higher physical performance.

10. Ensure Proper Hydration & Electrolytes

Dissolve one packet of Element in 16-32 ounces of water first thing in the morning and during physical exercise to ensure proper hydration and adequate electrolytes (sodium, magnesium, potassium) for optimal brain and body function.

11. Support Basic Nutritional Needs

Take Athletic Greens once or twice a day to cover basic nutritional needs, make up for deficiencies, and support microbiome health with probiotics.

12. Supplement Vitamin D3K2

Supplement with Vitamin D3K2 as D3 is essential for brain and body health and K2 regulates cardiovascular function and calcium in the body.

13. Utilize Meditation & NSDR

Use the Waking Up app for meditation, mindfulness, yoga nidra, or non-sleep deep rest (NSDR) sessions of varying durations to place the brain and body into different states and restore cognitive and physical energy.

14. Prioritize Metabolic Stress in Lifting

When lifting for muscle growth, prioritize metabolic stress by keeping rest periods around two minutes, rather than extending them to lift heavier. Shorter rests drive a more beneficial metabolic environment.

15. Intense Lifting Frequency

For challenging, high-intensity resistance training protocols like six sets of ten repetitions at 80% 1RM, aim for about two times a week to allow for adequate recovery and sustained progress.

16. Diversify Weekly Workouts

Beyond intensive muscle growth protocols, incorporate other workouts throughout the week with varying emphasis, such as higher volume (12-20 reps, lower intensity) or lower volume (higher intensity) to target different fitness outcomes like endurance or power.

17. Enhance Pre-Workout Arousal

Utilize pre-workout routines and music to enhance sympathetic arousal, as this prepares the body for challenging physical exertion and can lead to increased epinephrine/norepinephrine release and improved performance.

18. Adapt to Stressors Over Time

Understand that repeated exposure to the same stressor will lead to accommodation; the body adapts, so new or increased stressors are needed to continue driving adaptation and performance improvements.

19. Cold for Competition Recovery

During competition phases, when the goal is to maintain performance and technical execution rather than build muscle, use cold exposure as a recovery intervention to reduce inflammation and optimize the body.

20. Cognitive Engagement in Skill Learning

During skill learning sessions, engage consciously and cognitively, aiming for mental fatigue as much as physical. Complete engagement in the learning process is essential for effective motor skill acquisition.

21. Avoid Full Ketosis for High-Intensity Sport

For high-intensity, intermittent sports, avoid a completely ketogenic diet, as carbohydrate fueling is often required for optimal performance during high-intensity efforts.

22. Cycle Ketosis for Metabolic Efficiency

For general health or during periods of lower-intensity activity, consider cycling into ketosis to improve metabolic management and efficiency, teaching the body to preferentially use fats as fuel.

23. Train Metabolic Fuel Utilization

Actively train your body to preferentially use fat at lower exercise intensities and carbohydrates at higher intensities through diet and exercise manipulation. This prevents early fatigue and optimizes fuel availability.

24. Assess Interventions Over 12 Weeks

When trying a new training regimen, diet, or recovery intervention, commit to a 12-week period. This is generally sufficient to observe physiological adaptations, progression, or regression within the body.

25. Cultivate a Beginner’s Mindset

Cultivate a ‘white belt mentality’ or beginner’s mindset, continuously seeking to learn and adapt. New insights and understanding of human performance emerge daily, even with extensive experience.
