Dr. Kelly Starrett, a physical therapist, coach, and author, has revolutionized the way athletes and everyday individuals approach mobility, performance, and pain management. His philosophy, articulated through his company The Ready State (formerly MobilityWOD) and his bestselling books, emphasizes that all human beings should be able to perform basic maintenance on themselves to move freely and live a full, pain-free life. [1][2]

On Mobility and the "Supple Leopard"

The "supple leopard" is Starrett's metaphor for the ideal state of physical being: an individual who is not only strong and powerful but also agile, flexible, and pain-free. [3]

  1. On the definition of mobility: "'Mobility' is a kind of wonky term that refers to something quite beautiful: the harmonious convergence of all the elements that allow you to move freely and effortlessly through space and life. Everything is in sync – your joints, muscles, tendons, ligaments, fascia, nerves, brain, and the vasculature that runs through the body.” [4][5]
  2. The goal of mobility: "Mobility is about having the range of motion you need to do what you want with your body, pain-free." [6]
  3. Proactive self-care: Starrett champions the idea of "mobility maintenance," which involves regularly addressing movement limitations to prevent injuries and enhance performance. [7] He believes our bodies should be maintained and tuned for optimum performance, much like a high-performance machine. [7]
  4. Mobility is for everyone: "Dr. Starrett's work is not limited to coaches and athletes; his methods apply equally well to children, desk jockeys, and anyone dealing with injury and chronic pain." [2]
  5. Daily commitment is key: He encourages a daily commitment to mobility work, suggesting at least 10 to 15 minutes each day to maintain joint health and prevent injuries. [8]
  6. Mobilizations over simple stretching: "Stretching is fine; go ahead and stretch if you like it. But if you want to have less pain, move more fluidly, and be better able to recover from physical stress...mobilizations, not stretching, are your ticket to success." [9]
  7. The body as a system: His holistic approach combines principles of physical therapy, strength training, and mobility work to create a well-rounded approach to human movement. [8]

On Pain and Injury Prevention

A core tenet of Starrett's philosophy is that pain is a signal that should not be ignored and that most non-traumatic injuries are preventable.

  1. Don't wait for pain: "Unfortunately, most people only think about mobility when pain enters the equation. But Kelly's on a mission to change the conversation." [1]
  2. Focus on performance, not just injury reduction: "No one cares about preventing injuries until they have gotten injured... The fix to this problem is to approach injury prevention from a performance improvement angle." [10]
  3. Movement as medicine: "We are designed to run, squat, jump... Move more because movement is medicine and no pill, brace or diet can change that." [10]
  4. Own your own pain: Starrett believes that with the right information, people can take responsibility for their own pain, movement limitations, and recovery. [2]
  5. Address the root cause: "Addressing the mobility alone is not sufficient, we need to change the underlying movement dysfunction." [11]
  6. Pain is not normal: He challenges the idea that aches and pains are a normal part of aging or training. Instead, they are indicators of poor mechanics or tissue restrictions that need to be addressed.

On Movement Principles

Starrett outlines several fundamental principles for safe and effective movement that apply to both elite athletics and daily life.

  1. Prioritize spinal mechanics: Maintaining a neutral, braced spine is the foundation of all safe and powerful movements. [3][8]
  2. The Bracing Sequence: He provides a step-by-step guide to achieving spinal stability, which is crucial for protecting the back and generating force. [8]
  3. Generate Torque: "Torque: The Key to Joint Stability and Force Generation." [8] Creating torque by externally rotating the hips and shoulders stabilizes these joints and is essential for powerful movement.
  4. The One-Joint Rule: When moving, the primary motion should come from the hips and shoulders, while the spine remains stable. This protects the back from injury. [8]
  5. Movement Hierarchy: Starrett created a framework for understanding and progressing movement patterns, from basic to complex. [7][8]
  6. Innate range of motion: "Humans should be able to complete basic movements from the moment we get out of bed. We should have normal range of motion in our joints prior to the warm-up." [11]
  7. The warm-up's true purpose: "The shorter the event, the more speed and power required, the more warm-up." [4][9] The goal is to prime the system, not to create range of motion you don't already have. [11]
  8. Get hot: "I think that there's really one box [for a good warm-up] and that is getting tissue warm full stop done yeah get hot right." (Source: The Ready State Podcast, https://www.youtube.com/watch?v=Ddumv0TaK4E) [12]

On Modern Lifestyles (Sitting, Walking, Sleeping)

Starrett is a vocal critic of sedentary modern life and offers simple, actionable correctives.

  1. Sitting is the new smoking, but it's the lack of movement that's the problem: "While people have latched onto the catch-phrase 'sitting is the new smoking,' it's not sitting itself that harms us but rather lack of movement." [13]
  2. The danger of prolonged sitting: "Women and men who sit more than six hours a day are, respectively, 37 percent and 18 percent more likely to die before people who sit less than three hours a day." [4][13]
  3. Exercise won't reverse the effects of sitting: "The cold, hard truth is that exercise will not reverse the potentially harmful and irrefutable effects that too much sitting has on our bodies." [9]
  4. The power of walking: "We need to walk because walking gets everything flowing in our body. It's how we nourish all our tissues, how we decongest, how we stimulate the body to release waste.” [4][13]
  5. Sit on the floor: "Your ultimate goal here is to work up to sitting on the floor at least thirty cumulative minutes a day, every day.” [13] This simple habit improves hip mobility and counters the effects of sitting in chairs. [6]
  6. Sleep is non-negotiable: Starrett emphasizes that adequate sleep (7-8 hours) is fundamental for healing, learning, and hormonal regulation. [14] He debunks the "hustle culture" myth of thriving on little sleep. [14][15]
  7. Create a movement-rich environment: We need to consciously reintroduce varied movements into our daily routines to expand our "movement vocabulary." [6]

On Breathing

Breathing is not just for survival; it's a tool for stability, performance, and pain management.

  1. Breathing and mechanics are linked: "How well you breathe has a direct correlation to your body mechanics, helping you move more efficiently, avoid injury, and feel less musculoskeletal pain." [9]
  2. Nasal breathing is superior: He advocates for "breathing slowly and breathing through your nose rather than your mouth, even, whenever possible, during times of exertion.” [13]
  3. Breathing as an intensity gauge: "You should always be able to take a full breath while doing any kind of mobilization. Breathing is a great built-in 'intensity gauge.'" [13]
  4. Increase CO2 tolerance: "The longer you can hang on to carbon dioxide in your system, the more oxygen you'll be able to utilize... the more energy you'll have available for whatever it is you want to do.” [4][5]

On Mindset and Consistency

Lasting change comes from consistent habits, not heroic, unsustainable efforts.

  1. Consistency over heroism: “Before you show me heroic, show me consistency.” (Source: The Better Man Podcast, https://manflowyoga.com/blog/kelly-starrett-better-mobility/) [1]
  2. Do what you can, but don't do nothing: This quote from his book Built to Move emphasizes that even small actions are better than inaction. [5][9]
  3. Small changes lead to big results: He advocates for integrating small, positive habits into your existing routines for long-term success. [1][15]
  4. The gym as a laboratory: The gym is a place to experiment and learn about your body's movement and limitations. [8]
  5. You don't win, you just play better tomorrow: "You don't win being a parent. You just play better tomorrow." This philosophy applies to health and fitness as well; it's a continuous practice. (Source: The Better Man Podcast, https://manflowyoga.com/blog/kelly-starrett-better-mobility/) [1]
  6. Lifestyle factors are the foundation: Nutrition, sleep, and stress management are the bedrock upon which movement quality is built. [8][16]
  7. Enjoy life: "Eat a cookie... You should enjoy life and if one cookie per day keeps you sane and happy it definitely outweighs whatever the negatives are." [10] This highlights his balanced, non-dogmatic approach.

  4. Balance is an unsung hero: "Of all the many physical competencies we possess, balance is the unsung hero... that affects just about every aspect of mobility.” [13][17]
  5. Rewild your body: This concept involves restoring the natural processes and movements our bodies were designed for. [13][14]
  6. There is no one-size-fits-all mobility plan: "Each person has unique mobility deficits and compensations... There is no mobility recipe for everyone." [11]
  7. The Ready State: The goal is to be in a state of readiness, able to handle life's physical demands at any moment, rather than having to "turn it on." [18]
  8. Democratizing high performance: Starrett aims to take the lessons learned from elite performers and make them accessible and practical for everyone. [18]
  9. You are your own best advocate: "We believe that every human being should be able to perform basic maintenance on themselves. We wrote this manifesto back in 2008 and we still believe it." [2]
  10. Movement is a language: Modern lifestyles have narrowed our "movement language" to just a few "words." We must consciously work to expand this vocabulary. [6]
  11. You have more control than you think: "When people have better information, they can make better decisions." [2] Starrett's work is ultimately about empowering individuals with the knowledge and tools to take control of their own physical well-being.
