The shape of it

Tell Stronge you’re managing something (an Achilles, a patellar tendon, a hip) and a staged protocol starts underneath everything else:

  1. Calming isometrics. Holds first. Quiet the area before you load it.
  2. Heavy slow strength. Load the tissue, slowly, under weight, when completions are clean.
  3. Spring work. Return the stretch–shorten cycle that running and riding actually use.
  4. Sport-specific loading. Then the running or riding the injury has to survive.

Each rung has a number of clean sessions that steps you up. A pain flag on the flagged movement resets the count on that rung; a settled morning the next day withdraws the flag. The ladder never disappears; stage one is the floor.

Why it runs underneath, not instead

You keep your plan. The ladder shapes the session, deciding what is forced in and what is held back, without replacing the strength and mobility work for the rest of you. The session says which pins or exercises were held back and why (a clinical rule, your kit, the time you had).

What it is not

It is not medical advice and it does not replace a physiotherapist. Stronge’s clinical rules are hand-written and sit above the engine: contraindicated work does not appear, whatever you pin.
