Starrett treats health behaviors like vital signs: objective values that tell you whether to pay attention, the way blood pressure of 120 over 80 does. The book distills years of elite work into a handful of hinges that swing the biggest doors, each with a benchmark you can clinically validate against any goal. Movement becomes a vital sign at roughly 6,000 to 8,000 steps a day. Nutrition gets benchmarks of about 0.7 to 1.0 grams of protein per pound of bodyweight and 800 grams of fruits and vegetables for micronutrients and fiber. Mobility keeps two original objective measures from Becoming a Supple Leopard: non-negotiable range of motion, and output such as wattage and poundage. Because these are first principles, a vegan, a carnivore, or a powerlifter can all hit them, letting the benchmarks respect identity while still measuring what matters.
Origin
Starrett and Juliet Starrett distilled 15 to 20 years of work with elite teams and athletes into a set of vital-sign benchmarks, extending the two objective measures (range of motion and output) first published in Becoming a Supple Leopard.
Core principles
- 01Give people objective values, like blood pressure, so they know if they are above or below
- 02Range of motion is non-negotiable; output is the second objective
- 03First principles validate against any sport or goal you choose
- 04Benchmarks respect cultural and personal identity while still measuring
How to run it
- 1
Set the movement benchmark
Aim for 6,000 to 8,000 steps a day, where most of the health benefits of moving start to appear. Push to 10,000-12,000 if you struggle to fall asleep.
Pro tip It is about total movement and fidgeting, not just formal step count.
Watch out Don't treat 15,000 steps as a pass/fail line; the good benefits kick in far earlier.
- 2
Set the protein benchmark
Target about 0.7-0.8g protein per pound of bodyweight if sedentary, and roughly 1g per pound if growing, injured, or changing body composition.
Pro tip Spread protein across the day rather than cramming it into one meal.
- 3
Set the micronutrient benchmark
Eat 800 grams of fruits and vegetables daily for the micronutrients and fiber linked to major improvements in health and chronic disease.
Pro tip Expand food rather than restrict it; a pound of cherries is only about 230 calories.
- 4
Keep range of motion non-negotiable
Hold the native ranges every clinician expects, such as a hip that squats to around 120 degrees, as a fixed objective.
- 5
Track output and validate against your goal
Use output like wattage and poundage as the second objective, then prove the benchmarks by testing them against whatever goal you care about.
Pro tip First-principle benchmarks let you validate them in any sport or context.
In the wild
At Dave Asprey's conference, a woman gasped when Starrett mentioned eating two bananas, worried about the sugar. He pointed out she had eaten zero fruits and vegetables that day and an 800-calorie fat coffee with no micronutrients, while his two bananas cost about 170 calories and delivered nutrients. The exchange illustrates how a micronutrient benchmark, rather than fear of individual foods, keeps the focus on what the body actually needs.
→ The benchmark reframes food choices around nutrient density instead of fad-driven fear.
Common mistakes
Chasing an arbitrary number
Prescribing 15,000 steps or an exact stretch duration turns a useful benchmark into a pass/fail cudgel; the benefits start far lower.
Restricting food instead of expanding it
Cutting foods to lose weight often strips out the micronutrients and protein the benchmarks exist to guarantee.
Is it for you?
Best for
Anyone who wants a durable, goal-agnostic set of health targets instead of chasing fads.
Not ideal for
People seeking a single rigid prescription with no room to adapt to their own life.
From the transcript
“when we give people objective values... they can say, okay, I'm above or below that”
“we really can start to see a lot of the good benefits of moving more kick in at six to eight”
