Actionable Insights

1. Understand HRV

Learn about Heart Rate Variability (HRV) as a biomarker of resilience, as a higher HRV indicates greater control over your autonomic response to stress.

2. Commit to 10-Week Breathing Protocol

Engage in a 10-week protocol of resonant frequency breathing for 15 minutes, twice daily, to strengthen the baroreflex and create an automatic, moderating response to stress.

3. Find Your Resonant Breathing Rate

Identify your personal resonant frequency breathing rate (typically 5-6.5 breaths per minute) that maximizes heart rate oscillations, using tools like Elite HRV or CoreSense, or by finding the rate that feels most effortless.

4. Schedule Daily Breathing Sessions

Practice resonant frequency breathing for 15 minutes upon waking and 15 minutes before bedtime to enhance deep, restorative sleep and address sleep issues.

5. Train Physiology for Mind Control

Begin by training your physiology, specifically heart rate variability and heart oscillations, as this is the foundational step to gaining control over your mind and self-talk.

6. Address Unhealed Trauma

Recognize that unhealed past traumas can shape your self-narrative and hinder personal growth; dedicate time and space to process and heal these experiences.

7. Integrate Life Experiences

Understand that all life experiences, positive and traumatic, shape you; learn to sit with them, feel deeply, and let go when needed, integrating them as energy and fuel rather than compartmentalizing them.

8. Optimize Physiology for Decisions

Prioritize optimizing your physiological state before and during decision-making, as a parasympathetic state enhances cognitive dexterity, allowing you to see multiple options rather than being myopic.

9. Cultivate Parasympathetic Flow State

Learn to shift into a parasympathetic state, which is characterized by being open, engaged, aware, and receptive to the moment, rather than just calm, allowing for optimal response to situations.

10. Track Your HRV Range

Use tracking devices like Oura Ring or Elite HRV to understand your personal HRV range, noting nocturnal HRV and the differences between your highest and lowest days to identify influencing factors.

11. Reduce HRV Variability

Aim to decrease the disparity in HRV readings between nights, striving for more consistent, higher HRV levels to improve the body’s ability to process the world and perform at its peak.

12. Connect to Heart-Moving Experiences

Identify three personal experiences that evoke deep feelings of inspiration, gratitude, or love, and during your inhale, connect to that feeling, then on the exhale, release the rest of the world, training your heart to activate these states on demand.

13. Visualize Loving Moments During Breathing

During 15-minute breathing sessions, visualize and deeply feel your best moments with loved ones, embracing these emotions and then learning to let them go and bring them back, fostering emotional healing and openness.

14. Shift Physiological State Instantly

Develop the ability to rapidly shift your physiological state from sympathetic (fight or flight) to parasympathetic (flow) in just a few breaths during stressful moments.

15. Use Breathing Before Key Decisions

Implement 3-5 breaths of resonant frequency breathing immediately before critical decision-making moments (e.g., timeouts) to center yourself and make optimal choices.

16. Master Energy Fluctuation

Understand that peak performance isn’t about maintaining a single state, but rather about skillfully fluctuating your energy and manipulating the environment and momentum to create positive effects.

17. Prioritize Restorative Sleep

Recognize that high HRV correlates with better sleep, while low HRV is linked to sleep issues; prioritize restorative sleep to positively impact your HRV and overall resilience.

18. Practice Consistent Meal Timing

Eat at consistent, timed intervals (e.g., 7 AM, 1 PM, 6 PM) five days a week, as this predictability creates a sense of safety in the body, which is a precursor to a flow state and maximizes HRV.

19. Monitor Alcohol Intake

Understand your body’s specific response to alcohol by observing its impact on your HRV; if two glasses significantly lower it, consider avoiding alcohol during the week, competition, or training decision-making periods.

20. Limit Caffeine Intake

Keep caffeine consumption to two cups or less, as five or more cups of coffee can negatively impact daily performance and heart rate variability.

21. Create a Flow State Music Playlist

Develop a personalized playlist of 5-8 songs that consistently keep you in a flow state and promote a parasympathetic state, using it an hour before high-stakes events to optimize your body and mind.

22. Expect and Accept Stress

Acknowledge that stress is inevitable, which helps in managing its impact rather than being caught off guard.

23. Control Stress Duration

Aim to control the duration of stress responses, returning to a physiological baseline as quickly as possible to maintain performance and well-being.

24. Cultivate Malleability for Stress

Develop a malleable body, mind, and heart to adapt to varying forms of stress, understanding that stress is inevitable but its manifestation differs, allowing you to handle opportunities effectively.

25. Develop Somatic Awareness

Train yourself to identify whether you are in a fight-or-flight (sympathetic) or flow (parasympathetic) state, as making important decisions or competing from a parasympathetic state is crucial for optimal outcomes.

26. Control Self-Talk via Physiology

Gain physiological control over your heart and brain responses to inhibit negative self-talk, noise, and fear, thereby gaining control over your internal narrative and fostering positive self-talk.

27. Implement Post-Game Recovery Routine

After intense events, follow a recovery routine including a hot shower, stretching, a 15-minute breathing session, and a diet of easily digestible foods like steamed vegetables to aid body recovery and sleep.

28. Use Breath Pacer Apps

Utilize breath pacer apps like Breathe Plus, Awesome Breathing, or Easy Air to guide your breathing at different rates and identify your most effortless, resonant frequency.

29. Track HRV Periodically

Avoid obsessive daily HRV tracking; instead, monitor it periodically (e.g., once a week or every few weeks), or specifically during weeks 1, 4, 7, and 10 of a training program, to observe baseline changes.

30. Utilize Quick Physiological Shifts

Employ immediate actions like 20 jumping jacks, listening to specific music, or finding a quiet, safe space to quickly shift your physiology and return to baseline in stressful moments.

31. Choose a Guiding Word

Select a guiding word for a specific period (e.g., a year or six months) and intentionally apply its meaning to every area of your life to drive continuous improvement.

32. Avoid Holding Breath Under Stress

Be aware of the tendency to hold your breath during stressful moments, as this tenses the body and hinders proper decision-making; instead, maintain proper breathing.

33. Execute Predetermined Acts

Plan and execute predetermined actions, even if they feel uncomfortable initially, to intentionally shift momentum and energy in critical situations, allowing others to feed off your controlled oscillation.

34. Return to Baseline After Action

After an intense, momentum-shifting action, consciously bring your heart rate down and oscillate back to baseline to maintain a technical, clear approach for subsequent decisions.

35. Anticipate Stressful Moments

By maintaining a physiological baseline and building body-mind awareness through breathing, you can anticipate stressful moments and prepare yourself to operate effectively.

36. Improve Risk Assessment

Through physiological control, develop a more precise and multi-strategic approach to risk assessment, allowing for calculated and intentional risk-taking without the typical sympathetic over-activation.

37. Heal Trauma for Self-Compassion

Understand that a lack of self-compassion may stem from unhealed past traumas; actively engage in processing these emotions to cultivate greater self-compassion.

38. Take Emotional Risks for Self-Expression

To access deeper emotional connections, practice taking emotional risks in life, fostering greater self-expression and authenticity.

39. Continuously Reinvent Yourself

Focus on consistent self-improvement, aiming to be a better person each year by constantly finding small areas in your life to reinvent and grow.

40. Strive for Daily Consistency

Define success by your daily consistency in pursuing personal and professional goals, striving to be a consistently improving person in all areas of life.

41. Engage in Endurance Sports

Participate in endurance sports (e.g., running) to increase and maximize your HRV, especially if you naturally have a large HRV.

42. Seek ADHD Alternatives

If using excessive caffeine (e.g., 12+ cups) to self-medicate for ADHD, explore alternative methods with an MD’s recommendation to avoid sacrificing HRV and autonomic flexibility.

43. Avoid Chronic Alcohol Use

Be aware that chronic alcohol consumption can lead to a sustained reduction in HRV, indicating distress on the body and reduced autonomic flexibility.

44. Avoid Late Night Eating

Observe how eating within three hours before bedtime affects your sleep quality and adjust your eating schedule accordingly to improve rest.

45. Identify Personal HRV Amplifiers

Pay attention to daily activities or interactions that naturally elevate your HRV, and incorporate more of these heart-moving experiences into your routine.

46. Use Breathing for Night Wake-ups

If you experience multiple wake-ups due to a racing mind, employ specific breathing techniques to help you return to sleep.

47. Turn Off Your Brain for Sleep

Develop the ability to quiet your mind before sleep, as a busy brain prevents deep recovery and negatively impacts REM and deep sleep cycles.

48. Cultivate Empathy and Connection

Through self-awareness and emotional work, develop increased empathy and the ability to connect with others by meeting them where they are.

49. Influence Environment with Breathing

Use breathing and self-awareness to actively influence the energy and momentum of your environment, such as in a game or meeting.

50. Re-Center During Stoppages

Utilize natural pauses or stoppages (like timeouts) to re-center, return to baseline, enhance cognitive dexterity and focus, review past transitions, and anticipate future ones for positive impact.

51. Position for Optimal Stress Response

Focus on positioning your physiology in the best possible state before encountering different kinds of stress, rather than rigidly planning for specific scenarios, to enhance your adaptive capacity.

52. Assess Trauma’s Impact

Build awareness of how past traumas are affecting you, discerning whether their impact is positive or negative, and then develop strategies to navigate these effects.

53. Build Self-Awareness to Lead

Develop a deep awareness of how your body, mind, and heart react to stress, enabling you to lead effectively and provide what your team needs in high-pressure situations.

54. Expect Cognitive Gains by Week 7

Understand that significant cognitive benefits like increased focus, creativity, authenticity, and dexterity typically manifest around week seven of consistent resonant frequency breathing practice.

55. Optimize Baseline in First 4 Weeks

Focus on consistent, regular resonant frequency breathing for the first four weeks to strengthen the baroreflex, leading to a faster ability to let go of stress and increased control over irritations.

56. Use HRV for Sleep Recovery

Utilize HRV tracking to objectively assess your body’s recovery from sleep, observing how different sleep durations (e.g., 5 vs. 8 hours) impact your resilience metric.

57. Find Your Optimal Sleep Rhythm

Maximize your sleep by tracking and identifying the specific amount of sleep (e.g., 7 or 9 hours) that best supports your body’s recovery and HRV.

58. Incorporate Abdominal Breathing

Ensure your breathing practice includes abdominal breathing, as this is a key component of the consistent, regular practice.

59. Trust Effortless Breathing Rate

If physiological feedback tools are unavailable, choose the breathing rate (from 5, 5.5, or 6 breaths per minute) that feels most effortless and natural, as this is often your resonant frequency.

60. Dance Along Emotional Spectrum

Embrace the ability to navigate and express a full range of emotions without restriction, empowering you to be deeply connected and responsive in every moment.

61. Pause Automatic Reactions

Gain physiological control to pause automatic reactions and consciously decide whether to engage with intensity or disengage, rather than instinctively responding.

62. Intervene Early in Oscillations

Become attuned to your internal state and recognize when physiological oscillations are occurring, allowing for earlier intervention through breathing or other tools.

63. Use Breathing as Re-Centering Ritual

Adopt resonant frequency breathing (e.g., 4-second inhale, 6-second exhale) as a personal ritual to re-center yourself in the present moment, letting go of past events and focusing on the task at hand.

64. Integrate Breathing On-Demand

Practice resonant frequency breathing (e.g., 4-second inhale, 6-second exhale) so consistently that you can deploy it on-demand whenever you feel yourself entering a suboptimal state.
