GUEST SERIES | Dr. Andy Galpin: Maximize Recovery to Achieve Fitness & Performance Goals

Feb 15, 2023 3h 5m 36 insights
In this episode 5 of a 6-part special series on fitness, exercise and performance with Andy Galpin, PhD, professor of kinesiology at California State University, Fullerton, he explains how to optimize post-training recovery and how to avoid overtraining in order to better achieve your fitness and exercise goals. He explains the cellular mechanisms of muscle soreness and pain, why adequate recovery is essential for all physical adaptations, and how to enhance recovery using breathwork, thermal, movement, and pressure-based techniques. He describes how overtraining impedes exercise progress and how to assess if you are overreaching or overtraining, by using specific biomarkers and indicators. Like other performance metrics, recovery is a skill that can and should be trained, and that can be learned. This episode provides an actionable toolkit for how to monitor and improve your exercise recovery abilities, which will improve your overall mental and physical health.

Actionable Insights

1. Prioritize Recovery for Adaptation

Understand that progress and adaptation from exercise occur during recovery, not during the workout itself. Ensure your recovery strategies consistently outpace the stress input from training to achieve your fitness goals and avoid regression.

2. Balance Acute vs. Long-Term Recovery

Differentiate between optimizing for immediate recovery (e.g., for competition) and long-term adaptation. Acute recovery tactics might make you feel better now but could blunt long-term gains, so align your recovery methods with your overarching training goals.

3. Monitor Three Recovery Markers

To assess your recovery status and avoid overreaching, track three types of markers: a performance metric (e.g., speed, power), a physiological marker (e.g., HRV, resting heart rate), and subjective symptomology (e.g., mood, motivation, sleep quality).

4. Practice Down-Regulation Breathing Post-Workout

Immediately after training, engage in 3-10 minutes of structured nasal breathing (e.g., box breathing: inhale, hold, exhale, hold for 3-8 seconds each) to accelerate recovery by shifting your nervous system into a parasympathetic (calm) state.

5. Train Your Recovery System

Deliberately expose your body to controlled stressors through training, thermal exposure, and breath work to expand its capacity to handle stress and recover. This ‘widens your alley,’ making you more resilient and less sensitive to minor physiological deviations.

6. Understand Cortisol’s Dual Role

Recognize that cortisol spikes are essential for triggering exercise adaptation and anabolic responses, but chronically elevated cortisol is detrimental. Aim for sharp, high cortisol peaks during stress (like exercise) followed by rapid return to baseline.

7. Regulate Cortisol with Light and Sleep

Promote a healthy cortisol rhythm by getting bright light exposure (ideally sunlight) early in the morning to enhance the natural cortisol spike. Minimize psychological and physical stress 6-8 hours before bedtime to allow cortisol to naturally decline, aiding sleep and recovery.

8. Use Low-Level Movement for Soreness

If experiencing acute muscle soreness, engage in low-level, non-high-intensity movement (e.g., light cardio, active recovery) to contract muscles, pump fluid out of tissues, and alleviate discomfort more quickly than passive rest.

9. Measure HRV Consistently

Take Heart Rate Variability (HRV) measurements first thing in the morning, under consistent circumstances, for at least a month to establish your personal baseline and normal variations. Compare current readings to your historical average and the same day of the week to identify meaningful trends.

10. Act on Significant HRV Changes

If your HRV consistently deviates more than 5% outside your normal standard deviation for more than 3-5 consecutive days, it may indicate chronic overreaching. Consider adjusting your training load or deploying chronic recovery strategies.

11. Ignore Acute HRV Drops During Adaptation

If you experience an acute, single-day drop in HRV while in an adaptation phase (i.e., intentionally pushing training limits), do not immediately adjust your training. This drop might indicate that the training stimulus is effectively triggering adaptation.

12. Use Acute State Shifters for Bad Days

On single days when you feel poorly (but are not in a peaking phase), employ ‘acute state shifters’ such as physical movement (even hard training), up-regulation breathing, motivational music, or bright light exposure to quickly alter your mental and physical state.

13. Address Chronic Overreaching with Multi-Modal Strategies

If experiencing prolonged low HRV (over 7 days) or during a peaking phase, implement ‘chronic state shifters’ like thermal stress (cold/heat), enhanced sleep protocols, social connection, journaling, or meditation to facilitate deeper recovery and rebound.

14. Select 1-2 Key Recovery Metrics

Avoid tracking every possible recovery metric due to redundancy. Instead, choose one subjective daily measure (e.g., mood, libido) and one objective daily measure (e.g., HRV, CO2 tolerance test), plus a few quarterly/annually (e.g., blood work, body fat) that are relevant and accessible to you.

15. Utilize CO2 Tolerance Test

Perform the CO2 tolerance test daily under standardized conditions as a reliable, zero-cost indicator of systemic stress and recovery. This metric tracks closely with HRV and can provide good insight into your physiological state.

16. Wear Compression Gear for Soreness

Wear tight-fitting compression garments (pants, leggings, rash guards) during or immediately after strenuous workouts. This can help prevent and reduce muscle soreness by promoting fluid movement and enhancing blood flow in the working tissues.

17. Consider Cold Water Immersion for Acute Soreness

For acute muscle soreness, consider cold water immersion (e.g., 40-50°F for >15 minutes or sub-40°F for ~5 minutes). This is effective for reducing soreness, but be aware it may temporarily blunt hypertrophic adaptations if done immediately post-workout.

18. Ease into Cold Exposure and Circulate Water

When using deliberate cold exposure, start with tolerable temperatures and gradually increase intensity. To enhance the effect of cold water, make the water circulate around your body, as stillness allows a thermal layer to form.

19. Use Heat for Recovery with Caution

Hot baths or saunas can aid recovery by increasing blood flow. However, be mindful of potential acute swelling and, for males trying to conceive, avoid excessive heat exposure to the groin or use ice packs to protect sperm health.

20. Kickstart Recovery Immediately Post-Workout

Begin your recovery process as soon as your training session ends. This immediate transition from high stress to recovery is crucial for maximizing the adaptive signals and overall results from your workout.

21. Listen to Slow-Paced Music Post-Workout

Transition from stimulating workout music to slower, lower-cadence music immediately after your training session. This can help signal to your nervous system that the intense period is over and kickstart the recovery process.

22. Use Breathing for General Stress Reduction

Engage in deliberate respiration practices, particularly those emphasizing extended exhales, to significantly reduce overall stress levels and improve heart rate variability, contributing to better daily well-being and recovery capacity.

23. Prioritize Speed-Based Performance Tests

To detect early signs of overreaching or overtraining, use speed-based performance tests (e.g., vertical jump, medicine ball throw) rather than strength-based tests. Power and speed declines are often earlier indicators of fatigue.

24. Avoid Over-Reliance on Single Metrics

Do not make significant training or lifestyle decisions based solely on a single recovery score from an app or watch. These scores often combine multiple assumptions and may not accurately reflect your overall physiological state.

25. Practice ‘Drawing a Line’ for Focus

Before starting a training session, mentally or physically ‘draw a line’ and commit to not crossing it until you are fully ready to give the desired effort. This practice enhances focus and intentionality during your workout.

26. Engage in ‘Brain Games’ for Mental Shift

Use short brain games, puzzles, or playful activities (e.g., Tetris, thumb wars) to quickly shift your mental state before training or during a recovery dip. This can help break negative thought patterns and improve focus.

27. Use DALDA Questionnaire Periodically

Complete a comprehensive subjective survey like the DALDA questionnaire monthly or at the end of training phases. This provides a detailed assessment of overall well-being, sleep, and life stressors, facilitating deeper insights and conversations.

28. Monitor Body Fat Monthly/Quarterly

Track your body fat percentage monthly or quarterly, especially if maintaining weight or body composition. Changes in body fat can signal non-functional overreaching or overtraining, which are associated with appetite and metabolic disruptions.

29. Get Basic Blood Work Quarterly

Obtain basic blood work (e.g., CBC and CMP) quarterly to monitor hidden stressors. Look at markers like cortisol, DHEA, testosterone, inflammatory markers (e.g., TNF-alpha, IL-6), and the neutrophil to lymphocyte ratio for insights into your physiological state.

30. Be Cautious with Antioxidant/Cortisol Supplements

Avoid prophylactic use of high-dose antioxidant, anti-inflammatory, or cortisol-reducing supplements (e.g., Vitamin C/E, ashwagandha, turmeric) unless indicated by biological testing or specific training phases. These can blunt adaptation and cause unintended side effects like reduced libido.

31. Use Grip Strength as Low-Cost Metric

Purchase an inexpensive hand grip dynamometer and test your grip strength daily under standardized conditions. This provides a simple, low-cost objective metric that can indicate your recovery status.

32. Standardize Performance Test Conditions

When using performance tests (e.g., vertical jump, medicine ball throw) to assess recovery, standardize all conditions including warm-up, stretching, and load. Inconsistent pre-test routines can confound results and obscure true recovery trends.

33. Understand Your Normal Metric Variations

For all objective and subjective metrics, identify your personal normal range and standard deviation. Only consider taking action when values consistently fall outside this ‘gray zone’ of typical fluctuation, as what’s normal varies greatly between individuals.

34. Assess Libido as a Recovery Marker

Pay attention to your libido as a subjective indicator of recovery. Establish your personal baseline during a stable, low-intensity training phase and recognize that significant deviations can signal overreaching or other physiological imbalances.

35. Address Acute Soreness by Reassessing Training

If experiencing significant acute soreness, it’s often a sign that training volume or intensity was increased too quickly, or other life stressors are impacting your recovery. Reassess your training program and overall stress bucket before deploying symptom-treating tactics.

36. Use Carbohydrates Strategically

Ingest carbohydrates strategically, particularly in the evening, to signal energy availability to your body. This can help lower cortisol, promote sleep, and aid recovery by reducing the physiological need to liberate stored energy.
