Twenty-five is the standard

A healthy adult should manage in the region of 25 full-range single-leg heel raises. Most runners with shin pain cannot.

Return is judged on symmetry

Readiness to run is judged on heel-raise count and hop symmetry between legs, not on weeks passed.

Flares are normal

A flare that settles within 24–48 hours is sensitivity, not new damage. Hold the level, do not stop.

How to run it

  1. Straight knee loads the gastrocnemius, bent knee loads the soleus. Both, every week.
  2. The soleus is the one that carries running. It is trained with the knee bent and it is trained heavy.
  3. Three seconds up, one at the top, three seconds down. Count only full-range reps.
  4. Cramp means the muscle is working at a load it is not used to. Shake it out, drop a level, carry on.
