How to Improve Your Mobility, Posture & Flexibility | Dr. Kelly Starrett

KEYPOINTS

• 01

  Most people's 'movement language' has shrunk to a few words

  Starrett describes a typical day as sit, stand, walk slowly, with exercise that repeats the same shapes. An exercise bike or elliptical, for example, never asks for hip extension. Bodies are adaptation machines, so unused ranges stop being expressed and the brain may stop treating them as safe, which limits the movement options it will allow.

• 02

  Exposure is the first lever for restoring range of motion

  Before choosing techniques, Starrett asks how to expose the body to the range you want back. He cites a PT instructor's line that 'muscles and tissues are like obedient dogs': at no age do you stop adapting or healing, though both slow down. Time spent in hip, hamstring and ankle ranges lets tissue adapt.

• 03

  Cultures that live on the floor show fewer age-related problems

  Starrett notes that in cultures that toilet, sit and sleep on the ground, fall risk in older adults drops close to zero and rates of hip and low-back osteoarthritis are lower. He offers this as an association, suggesting that regularly using these shapes may tell the body to keep normal hip range.

• 04

  The sit-and-rise test works like a movement vital sign

  Cross your feet, lower yourself to the floor with control, then stand up without using hands or a knee. Ideally you should be able to do it with either foot in front. Starrett says the data show it predicts all-cause mortality and morbidity, but its real value is revealing a childhood skill you've lost because you're missing end ranges. He compares such 'movement minimums' to a blood pressure reference.

• 05

  Protect gym time and move maintenance work elsewhere

  Starrett criticizes 'decorative' fitness that fills sessions with accessory drills, and recursive training such as doing zone 2 only to do more zone 2. Gym time is 'sacred' and should go to squatting, pressing, sprinting and play. Mobility, floor time and small doses of loading belong at home, such as a loaded bar in the garage for sets while dinner cooks.

• 06

  Pain and stiffness can be handled with the 'D2R2' sequence

  Desensitize first (scraping, isometrics, rolling, blood-flow restriction), because a painful tissue can't produce normal force. Decongest next: swollen or congested tissue (including 'cankles' after a flight) is more sensitive and heals more slowly, and muscle contraction drives lymphatic drainage. Then reperfuse, since a pumped, warm tissue often hurts less; one example is a few minutes of leg extensions before heavy squats with an old knee issue. Finally, restore full normal range in the joint.

• 07

  Most pain is an 'incident', not an injury

  Starrett reserves 'injury' for pain or dysfunction so severe you can't fill your role at home, at work or on the team, which needs medical care. Everything else is an incident. He borrows Charles Perrow's idea of 'normal accidents' (via Laurence Gonzalez's 'Deep Survival'): breakdowns are often the system expressing itself after a long run of getting away with something.

• 08

  Foam rolling has evidence for pain and range of motion, but it should target something

  There's no wrong way to roll, says Starrett, only ways that waste time. The research is clear that soft-tissue work can reduce pain and restore range. He points to Brent Brookbush's institute for research summaries and recommends asking what's stiff or painful today rather than mindlessly rolling the whole body.

• 09

  A tight pelvic floor needs relaxation, not more Kegels

  Huberman recounts prostate pain in his 30s with a normal PSA that he traced to a tight pelvic floor. Citing Dr. Michael Eisenberg, he says Kegels can worsen urinary and erectile function when the pelvic floor is already tight. Starrett suggests mobilizing around the pelvis and glutes with a ball, staying away from the sit bones and soft areas and using contract-relax. Pain under compression tells you where the problem is.

  Hip extension is a weak spot for most people

  Starrett ties the back extensors, glutes, hamstrings and calves into one extension system (drawing on Philip Beach and Thomas Myers' Anatomy Trains). Without hip extension, the hamstrings take on extra work. Yoga's camel and wheel poses are useful tests of whole-spine extension, which he prefers to loading one or two segments as in an anterior pelvic tilt. He notes B.K.S. Iyengar introduced blocks and belts to support students into shapes they couldn't reach.
