Phase 4 · Load and endurance · Session W

Both muscles.
Both ends.
Both legs.

The full calf and shin load in one session, straight-kneed and bent, with the endurance to back it.

The calf is two muscles

Gastrocnemius crosses the knee and the ankle; soleus crosses only the ankle. One programme has to load both.

Both legs get weak

After calf or shin pain, strength deficits usually show on both sides. Train the good one too.

Two sessions a week holds it

Calf strength fades within weeks of stopping. Two sessions a week keep thirty days of work in place.

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.
