Pain as a Request for Change

Pain is a signal from the body indicating a need for attention or adjustment, rather than an automatic sign of injury. It can be influenced by factors like stress, sleep, and nutrition.

Desensitization

Techniques (like massage, scraping, isometrics) used to reduce the brain's interpretation of a symptom or information as a threat, thereby decreasing perceived pain and increasing tolerance for movement.

Movement Choice

The ability to access and utilize a full range of motion and diverse movement patterns, allowing the body to adapt to various physical demands and solve movement problems effectively.

Ventilation Efficiency

The skill of breathing effectively, utilizing the full range of motion of the trunk and diaphragm, which impacts spinal mobility, force production, and CO2 tolerance during physical activity.

Intra-abdominal Pressure

The pressure created within the abdominal cavity by breath control, crucial for spinal stability and force production during heavy lifts, which can be trained to improve lifting performance.

Sedentary Behavior

Any activity that involves falling in half below 1.5 metabolic equivalents (METs), such as prolonged sitting. Breaking these bouts with movement can significantly improve health outcomes.

Movement Snacks

Short, informal bursts of physical activity integrated throughout the day, which can significantly improve health, reduce sedentary risks, and enhance overall well-being, even without formal exercise.

Musculoskeletal Syndrome of Menopause

A condition affecting women in their 40s and 50s, where hormonal changes (like decreased estrogen) can lead to occult tendon issues, frozen shoulder, and other musculoskeletal problems.

Youth Sport Industrial Complex

A system where youth sports become overly structured, specialized, outcome-driven, and expensive, often leading to high injury rates, burnout, and kids dropping out due to lack of fun and focus on development.

?
Does pain always mean you're injured?

No, pain is often a request for change from your body and can be modulated by stress, sleep, and nutrition, rather than a direct indicator of injury.

?
Can foam rolling help with pain and mobility?

Yes, research indicates foam rolling can help with range of motion, blood flow, and desensitizing painful areas, especially when combined with controlled breathing and muscle contraction.

?
Do you need to be sore to have had a good workout?

No, soreness is not a prerequisite for a good workout; while beginners may experience it, over time, excessive soreness can hinder performance and doesn't necessarily indicate progress in strength or bone density.

?
What should a warm-up accomplish?

A warm-up should prepare your body by increasing tissue readiness, improving movement quality, and enhancing performance, rather than solely focusing on injury avoidance.

?
How can I assess hip mobility at home?

Simple tests include being able to squat with your hip crease below your knee, pulling your knee past 90 degrees while standing on one leg, or performing the sit-and-rise test (lowering and rising from the floor without support).

?
Can the sit-and-rise test predict longevity?

The sit-and-rise test is a proxy for overall movement choice, balance, and ability to solve movement problems, which are associated with longevity, rather than being a direct predictor itself.

?
Why is breathing mechanics important for spinal mobility?

Efficient breathing, particularly diaphragmatic and lateral rib expansion, mobilizes the trunk and improves shoulder blade function, which in turn enhances overall arm function and spinal health.

?
Can breath holds improve athletic performance?

Yes, practicing breath holds (hypoxic work) can train the brainstem to tolerate higher circulating CO2 levels, allowing for greater oxygen utilization from hemoglobin and improved work capacity during high-intensity exercise.

?
How should non-athletes think about training?

Non-athletes should focus on finding enjoyable ways to move their bodies in community, aiming for minimum effective doses of loading and cardiorespiratory demand, and integrating movement throughout the day rather than adhering to rigid, specialized training plans.

?
Why is floor sitting important?

Floor sitting helps maintain hip and knee range of motion, improves the ability to get up and down independently (a key factor in avoiding nursing homes), and exposes the body to diverse postures that promote better joint function.

?
Why does mobility not have to decline with age?

Unlike some other physiological aspects, range of motion does not inherently have to decline with age; consistent practice and exposure to full body movements can maintain or even reclaim mobility.

?
Why are kids dropping out of sports at age 13?

Kids often drop out of sports around age 13 because it ceases to be fun, becomes overly focused on outcomes (winning/losing), and they are no longer playing with their friends in an enjoyable environment.

?
When should kids start strength training?

Formal strength training can be layered in as children move into middle school, focusing on bodyweight control, jumping, crawling, and sprinting, rather than heavy lifting. Gymnastics, tumbling, and parkour are good early forms of structured movement.

?
What should be removed from a young athlete's program before adding new things?

First, remove "junk volume" and overly specialized, "sciency-feeling" agility training that doesn't contribute to gross motor skill development. Focus on foundational movement skills and play.

1. Reframe Pain as a Request

View pain not as an injury, but as a signal from your body requesting a change. Don’t catastrophize; instead, become curious about what your body needs.

2. Desensitize Painful Tissues

Use simple tools like scraping, cupping, massage, isometrics, or percussion to reduce pain sensitivity and create a window for movement. This signals safety to the brain and can improve blood flow.

3. Prioritize a Comprehensive Warm-up

Treat your warm-up as an opportunity to assess your body’s readiness, remind the brain of fundamental movement patterns, get hot and sweaty, wake up the nervous system, and explore positions safely. The goal is improved tissue readiness and performance, not just injury avoidance.

4. Integrate Movement Throughout Day

Break up long periods of sitting by incorporating “movement snacks” or short bursts of activity. Aim for at least 8,000 steps daily to reduce all-cause mortality.

5. Practice Floor Sitting Daily

Spend 20-30 minutes daily sitting on the ground in various postures (cross-legged, kneeling, legs straight) to maintain hip and knee range of motion and improve your ability to get up and down independently.

6. Maintain Shoulder Mobility with Hanging

Incorporate hanging from a bar for a total of three minutes a day to improve neck, back, and shoulder health. This acts as an isometric exercise, signaling to the brain that overhead positions are safe.

7. Practice Intentional Breathing During Exercise

During static holds like planks or heavy lifts, focus on maintaining a large, controlled breath volume. This trains your brain to tolerate higher CO2 levels, improving work capacity and reducing reliance on breath-holding.

8. Prioritize Youth Athlete Sleep

Ensure children and young athletes get sufficient sleep per night. This is the most critical factor for injury prevention, recovery, growth, and athletic adaptation.

9. Promote Movement Diversity in Youth Sports

Encourage kids to sample multiple sports and engage in diverse movement activities (e.g., gymnastics, martial arts, track and field fundamentals like jumping, sprinting, throwing) rather than early specialization.

10. Protect Unstructured Play for Kids

Create opportunities for children to engage in free, unstructured play to develop motor skills, problem-solving abilities, and intrinsic motivation for movement.

11. Teach Fundamental Movement Skills to Youth

Incorporate basic calisthenics (push-ups, lunges, pull-ups), jumping, landing, tumbling, and throwing/catching games into youth training. Focus on bodyweight control and skill development through play, rather than heavy lifting too early.

12. Optimize Your Desk Setup for Movement

Use a standing desk with a footrest and a bar stool to allow for varied postures, fidgeting, and movement choice throughout your workday. This helps you stay above sedentary metabolic equivalents.

13. Use Soft Tissue Work for Recovery

Engage in 10 minutes of soft tissue work (e.g., foam rolling) in the evening to decrease delayed onset muscle soreness (DOMS), improve blood flow, and promote parasympathetic down-regulation for better sleep.

14. Breathe During Soft Tissue Work

When performing soft tissue work or foam rolling, ensure you can breathe deeply and maintain some muscle control. If it’s too painful to breathe or control muscles, you might be signaling threat to your nervous system.

15. Use Breath Holds to Prime Nervous System

Incorporate short breath hold exercises during warm-ups or low-intensity activities (like cycling or walking) to improve CO2 tolerance and prepare your nervous system for higher workloads.

16. Engage in Leisure Time Activity

Dedicate at least one hour per week to enjoyable, non-structured physical activities like dancing, playing tennis, or group bike rides. This fosters community, joy, and often provides additional fitness benefits.

17. Incorporate Running for Recovery

If you experience soreness after heavy training, going for a light run the next day can significantly aid recovery by increasing blood flow, restoring tissue gliding, and reducing DOMS.

18. Use Heat Exposure for Recovery

Utilize saunas, hot tubs, or hot baths to increase blood flow, promote relaxation, and potentially aid tissue healing. This is a low-skill way to improve recovery.

19. Consider Cold Exposure Judiciously

While cold exposure can build psychological resilience, use it carefully around training if your goal is maximal adaptation, as it can blunt some exercise benefits. For general well-being, short cold exposures are beneficial.

20. Focus on Foundational Nutrition

Prioritize eating adequate fruits, vegetables, and protein. This approach naturally controls calories, improves gut health, and supports overall tissue and bone health.

21. Increase Outdoor Time

Aim to spend more time outdoors, especially in green, natural environments. This improves mental health, circadian rhythm, and fosters community.

22. Ruck for Added Load and Fitness

Incorporate rucking (walking with a weighted backpack or vest) to add load, improve bone density, and enhance fitness, especially if running isn’t feasible. Start with a comfortable weight and gradually increase.

23. Fuel Young Athletes Adequately

Address underfueling in young athletes by ensuring consistent, nutritious meals and appropriate snacks, especially around late practices. Prioritize whole foods over reactive, processed options.

24. Remove Junk Volume from Youth Training

Prioritize removing unnecessary, non-beneficial training volume and overly specialized, “sciency-feeling” agility drills from youth programs. Focus on gross motor skill development and play.

Pain is a request for change.

Dr. Kelly Starrett

Your brain interprets what's going on with your body. Your elbow isn't screaming pain. Your brain thinks that that is maybe a threat signal or it's interpreting this symptom, this information as threat.
