When somebody involves me with an harm (or a kind of nagging aches that’s been hanging round for weeks they usually can’t determine why) I run the identical diagnostic virtually each time.
It’s easy. You possibly can run it on your self. And it’ll train you what to search for to dodge future points.
The three-part diagnostic
I’m in search of a latest spike in any of those three:
- Quantity – how a lot of the factor you’re doing
- Depth – how exhausting the factor is
- Novelty – how new the factor is to your physique
An enormous soar in any ONE of those will increase your harm danger. A soar in two or three without delay? Bingo.
Listed here are some examples:
- You fall in love with a brand new passion, like mountaineering (novelty), and spend hours on the climbing fitness center your first week (quantity), however decide up a nagging wrist harm you possibly can’t appear to shake.
- You resolve to join a half-marathon race together with your pal. A couple of weeks out, you soar proper into the later phases of a coaching program to catch up (quantity & depth), however get shin splints and may’t full the race.
- You begin a brand new power coaching program and resolve to max out on every carry to actually take a look at your self (novelty, depth), however partway by way of your shoulder does one thing funky and now it aches if you attempt to sleep in your aspect.
Operating the diagnostic in actual life
I’ve been teaching Steve (founder and Insurgent Chief of Nerd Health) for the final couple of months, and just lately his again began getting tight after a spherical of golf.
After we ran the diagnostic, issues turned clearer:
- His step rely jumped from round 6,500 on a traditional day to 17-20k on golf days (quantity spike)
- He went from sitting at a desk straight into cranking full-power swings (depth spike)
- Golf additionally asks the physique for rotational energy it doesn’t get a lot of day-to-day (novelty spike)
His again was responding as we’d count on after we flip the dial up on all three variables without delay.

Right here’s how we use that data to construct a plan.
✅ Increase his baseline day by day strolling week over week so 15k+ steps isn’t a shock to the system
✅ Construct in an actual warm-up earlier than he tees off to prep his physique correctly
✅ Create a much bigger buffer of power, mobility, and stability within the areas golf calls for most (rotation, hip mobility, and many others.)
The larger concept: graded publicity
This diagnostic works as a result of it factors on the identical precept operating beneath virtually the whole lot we do in teaching: graded publicity (AKA Progressive Overload).
Energy coaching? The purpose is to problem your physique simply the correct quantity. Too little, nothing occurs. An excessive amount of, you place your self in danger. It’s the Goldilocks zone we’re after. 👧🐻🐻🐻
Coaching for an occasion? Give your self loads of time to construct up for it so that you by no means need to spike up your depth or quantity on the identical time. My consumer CJ simply completed a half marathon and felt wonderful the entire means – however solely as a result of we spent 16 weeks of constant, gradual coaching getting him prepared. He’d beforehand handled shin splints and different points. This time? Harm-free. Right here’s what he messaged me after the race:
Rolling away from bed and operating a 10k with some left within the tank by the top was a distant dream a 12 months in the past! It was the proper day and a implausible race setting. I do know I put the work in, however I couldn’t have carried out this with out your plan and steerage, so I can not thanks sufficient! So, what’s subsequent coach? 😁

Recovering from an harm or persistent ache? First, ensure you get checked out by your doc. Good bodily remedy is mainly graded publicity with further steps. You’re slowly rebuilding capability and tolerance within the space, educating your physique it might deal with load once more.
Heck, this even applies to behavior change. An excessive amount of change without delay? Exhausting to maintain, straightforward to burn out. Too little change? Progress is so sluggish it’s exhausting to guage what’s working. We would like simply sufficient problem to maneuver the needle.
Similar precept. Totally different purposes.
Run the diagnostic on your self
Whether or not you’re feeling one thing nagging proper now, OR you’re about to start out one thing new (a category, a sport, a season, a undertaking) – ask your self:
- Am I (or did I just lately) make an enormous soar in quantity? (Quantity of the factor)
- Am I (or did I just lately) make a sudden leap in depth? (How exhausting the factor is)
- Am I doing one thing utterly new? (First Zumba class, first hike of the season, first pickup basketball recreation in 5 years)
In case you mentioned sure to 1 -> ease in. In case you mentioned sure to 2 or three -> actually ease in.
This doesn’t imply you possibly can’t do exhausting issues. It means giving your physique a good likelihood to maintain up with what you’re asking of it.
Degree up one step at a time. That’s the way you keep within the recreation for the lengthy haul. 💪
