Surface and shoes shift load

Changing surface, shoes or terrain changes where the load lands. Change one thing at a time and give it two weeks.

Calf strength and walking speed

Plantarflexor strength is the biggest single contributor to walking speed, and walking speed tracks with independence in later life.

Energy availability

Bone stress injuries are more common when training load is high and fuelling is low. Under-eating is a bone risk factor.

Each couplet: 60 s scored → the loading set → 10 s to move on. Done at 12:00.

How to run it

  1. Calf endurance fails long before calf strength does — that is why these sets are long.
  2. Bone and tendon adapt over months. Add load in small steps and let the week's numbers decide.
  3. Two clean sessions at a load earn the next. In doubt, add a rep before adding a kilo.
  4. Soreness in the muscle is fine. One sore spot on the bone that is worse the next day is not.
