Dr Kelly Starrett on Pain, Movement & Longevity: Key Insights from the FoundMyFitness Podcast with Dr Rhonda Patrick
Key insights: 60-second read
- Pain is a request for change, not a sign of injury - treat it as a check engine light, not a catastrophe. Most pain can be modulated through sleep, nutrition, stress, and movement.
- Walking 8,000 steps daily reduces all-cause mortality by 51% - a simple, accessible benchmark that most people can achieve without formal exercise.
- Soft tissue work (foam rolling, lacrosse ball) is most effective in the evening - it promotes parasympathetic activation and better sleep when done 10 minutes before bed.
- You do not need to be sore to have a good workout - soreness is not a reliable metric of progress. Nutrition (iron, omega-3s) and recovery play bigger roles.
- The sit and rise test predicts longevity - being able to get up and down off the ground without support is a powerful proxy for overall functional capacity.
What if everything you thought you knew about pain, exercise, and recovery needed a rethink?
Dr Kelly Starrett - physiotherapist, coach to Olympians, and author of the bestselling book Becoming a Supple Leopard - joined the Found My Fitness podcast with Dr Rhonda Patrick for a wide-ranging conversation about movement, pain, longevity, and the modern sedentary lifestyle. As someone who has worked with elite athletes, Navy SEALs, and everyday people, Starrett brings a refreshingly practical perspective to how we should think about our bodies.
This article summarises the key insights from this conversation, covering everything from pain science and soft tissue work to youth sports, desk ergonomics, and the simple movements that can change your health trajectory.
"Pain doesn't always mean you are injured. Pain is a request for change. That is a great place to start. Use it a little bit like a check engine light."

Pain is a request for change
One of the most important reframes in the entire conversation is how Starrett thinks about pain.
"Pain doesn't always mean you're injured," he says. "Pain is a request for change. Use it a little bit like a check engine light." When your knee hurts after a run, do not panic. It is asking you to pay attention. Consider:
- Are you super stressed?
- Did you go drinking last night?
- Did you sleep poorly?
- How is your nutrition?
- Did you warm up properly?
- Did you go from redlining like an elite athlete straight to sitting at your desk?
The brain interprets pain as a threat signal. But that signal can be modulated by many factors. Starrett encourages becoming curious rather than catastrophising. "All the pros, everyone I have ever worked with, is basically like, 'I have never been 100%.' Maybe when I was 10 years old. Everything else is working around some discomfort."
The truth about sitting and movement
Starrett is clear: sitting itself is not bad. The problem is marathon bouts of sitting. Harvard defines a sedentary lifestyle as sitting more than six hours a day in aggregate (including TV, dinner, commuting).
The solution? Movement snacks and breaking up sitting time. "Walking 8,000 steps a day reduces all-cause mortality by 51%. That is a pretty good bargain."
Desk ergonomics tips from Starrett:
- Standing workstations are not enough until you have a place to put your foot (a stack or bar stool) to get out of extension
- A bar stool allows you to perch, lean, prop a foot, and change positions throughout the day
- Sitting on the floor for 20-30 minutes in the evening (cross-legged, kneeling, legs straight) exposes you to end ranges you never touch
"The number one reason people end up in nursing homes is they cannot get up and down off the ground independently. Let's practice that. Sit on the ground while watching TV. Your range of motion does not have to change as you age - as long as you are practicing it."
Soft tissue work: foam rolling and balls
Starrett is a fan of soft tissue work, but with important caveats.
"Foam rolling doesn't solve all the problems. If it solved all the problems, there would be no problems." However, the research is clear that soft tissue work can help with range of motion, blood flow, and desensitising painful tissues.
Practical guidelines:
- Limit to 5 minutes per muscle system to avoid overdoing it
- If it is so painful you cannot breathe, it is too much (you should be able to breathe and maintain muscle control)
- Do soft tissue work in the evening - it has a huge parasympathetic input and promotes better sleep
- Using a ball (lacrosse ball or tennis ball) allows you to target specific spots more precisely than a foam roller
Starrett also notes that research supports that soft tissue work after heavy training decreases DOMS (delayed onset muscle soreness).
The soreness myth
There is a pervasive belief that you need to be sore to have had a good workout. Starrett pushes back strongly on this.
"You do not have to get sore. Beginners will be sore, sorry not sorry. But over time, soreness gets in the way of your performance. It decreases force production."
The goal is to have a sufficient stimulus to disrupt homeostasis, not to brutalise yourself. Starrett shares a personal example: he recently discovered he needed iron and omega-3 supplementation. After addressing this, he gets less sore from his training.
"Did all that soreness change your bone density? Did you get stronger? You are just sore. You did a bunch of work and are sore. Again, you have not moved the needle; you have just created a lot of noise."
Range of motion and fundamental tests
Starrett advocates for simple movement tests that everyone should be able to perform.
The sit and rise test: Lower yourself to the ground cross-legged without falling, then stand back up without putting a knee or hand down. This test is a powerful proxy for overall functional capacity and has been associated with longevity.
Hip flexion: You should be able to pull your knee to your chest past 90 degrees while standing on one leg.
Shoulder internal rotation: With your elbow bent at 90 degrees and arm parallel to the ground, you should be able to rotate your hand up to 90 degrees and down to your hip (when lying on the ground) without your shoulder coming forward.
"Your range of motion is the one part of your physiology that does not have to change as you age. Muscles and tissues are like obedient dogs. They adapt and readapt. It will be slower than when you were 17, but you can reclaim that position and shape."
The warm-up: more than just preparation
Starrett views the warm-up as an opportunity to feel better, not just prepare for exercise.
"Who am I today as I show up at this gym? Your range of motion is a moving target - like a credit score. You are touching base with how tired you are, how springy you are. You are getting to know this carcass today."
A good warm-up should:
- Get you hot and sweaty
- Wake up the nervous system
- Remind the brain of fundamental movement patterns
- Be an opportunity to add play and exploration
- Include breath work and activation
Starrett notes that the first thing most people do when an exercise gets hard is hold their breath. "You are not actually limited by your strength; you are limited by your ability to manage oxygen use because you are not breathing."
Breath work and CO2 tolerance
Starrett incorporates breath work into warm-ups and training, particularly for athletes.
One example from French free divers: during a simple warm-up, take a 10-second inhale, then a maximum breath hold on that inhale. Recover with nose-only breathing. Repeat every minute.
Why does this matter? High levels of CO2 allow you to strip oxygen off haemoglobin. If you can train your brain stem to handle high circulating CO2 levels, you can tolerate higher workloads and get more work done while feeling less stressed.
"It is the CO2 that is triggering the breathing response. That is very trainable. You can suddenly get a lot more work done and feel better and less stressed on your body if you can handle those high CO2s."
Practical application: "At Berkeley, we try to have seven hypoxic events before we compete. We jump rope and hold our breath and put a little bit of that hypoxic load on. Later on in the pool or doing something of consequence, it is a lot easier."
Youth sports and athletic development
Starrett is critical of what he calls the "industrial youth sport complex." Most kids drop out of sports by age 13 because it is not fun anymore. Injuries are through the roof.
Key principles for youth athletes:
- Prioritise sleep - 8-10 hours minimum. No study says a child needs less than that.
- Prioritise nutrition - kids are chronically underfuelled, relying on energy drinks and reactive snacks.
- Do not specialise too early. Sampling multiple sports develops motor skills and problem-solving.
- Free play does not exist anymore. Parents need to create environments for it.
- Strength training can start early, but focus on bodyweight control, jumping, landing, and tumbling - not heavy loading.
"Norway does not keep score with kids until age 13. They have national programs that work on development so kids love it and continue to move. The goal is the most kids for the longest."
Starrett also notes that children's bones are softer than they used to be. Surgeons now hand-turn drills for ACL reconstructions because the cortical bone is so soft. This demineralisation is a real concern linked to lack of movement and loading.
Conclusion: train for life, don't live to train
The overarching theme of the conversation is summed up in Starrett's quote: "Train for life, don't live to train." Exercise and movement should be in service of living a full, enjoyable life - not an end in themselves.
For the average person, the goal is not Olympic-level performance. It is to have a body you can trust that does not hurt, to maintain movement choice, to pick up new skills, and to enjoy time with family.
Starrett's advice for where to start:
- Walk 8,000 steps a day
- Sit on the ground for 20-30 minutes in the evening
- Do 10 minutes of soft tissue work before bed
- Prioritise sleep and nutrition
- Find a way to move that you enjoy, ideally in community
As Starrett says, "What is the goal today? Find relative loads and relative speeds and relative skill - and then go on."
One key insight from this conversation
"Walking 8,000 steps a day reduces all-cause mortality by 51%. The number one reason people end up in nursing homes is they cannot get up and down off the ground. Your range of motion does not have to change as you age - as long as you are practicing it. Pain is not a sign of injury; it is a request for change."
Frequently asked questions
Is foam rolling actually effective?
Yes, for specific purposes. The research is clear that foam rolling can help with range of motion, blood flow, and desensitising painful tissues. However, Starrett emphasises that it is not a magic solution. For best results, spend 5 minutes per muscle system, breathe through any discomfort, and do it in the evening to promote parasympathetic activity and better sleep.
How do I know if my pain is serious or just normal?
If you have red flags (night sweats, dizziness, fever, vomiting, nausea, a clear mechanism of injury with a pop, or a bone sticking out), seek medical attention immediately. Otherwise, most pain is a feature of training, nutrition, and sleep. Treat pain as a check engine light. Consider your stress, sleep, nutrition, and recent activity before catastrophising.
What is the sit and rise test and why does it matter?
The sit and rise test involves lowering yourself to the ground cross-legged without using your hands, then standing back up without putting a knee or hand down. It is a powerful proxy for functional capacity and has been associated with longevity. Being unable to perform this test suggests missing range of motion, particularly in hip flexion, and should be addressed through floor sitting and mobility work.
Should I be sore after every workout?
No. Soreness is not a reliable metric of progress. Beginners will be sore, but as you adapt, excessive soreness gets in the way of performance and decreases force production. You want enough stimulus to disrupt homeostasis, not to brutalise yourself. Factors like nutrition (iron, omega-3s) and recovery have a major impact on soreness.
How can I help my young athlete avoid injury?
Prioritise sleep (8-10 hours). Ensure proper nutrition (kids are chronically underfuelled). Do not specialise too early - sampling multiple sports develops motor skills and problem-solving. Incorporate fundamental movement work: jumping, landing on one leg, tumbling, throwing. Avoid junk volume and private lessons that hyper-specialise too early. Make training fun - kids should want to play, not dread practice.
This conversation with Dr Kelly Starrett is a great practical discussion on movement, pain, and longevity. His approach is refreshingly straightforward: do not overcomplicate things. Walk more. Sit on the ground. Breathe intentionally. Play with your kids. Prioritise sleep. Eat real food.
If you are dealing with persistent pain, nagging injuries, or simply want to move better, start with the fundamentals. Test your sit and rise. Check your shoulder range of motion. Spend time on the floor. Break up your sitting with movement snacks. And remember: pain is not your enemy. It is information.
