Every angle.
Every stair.
Every rep clean.

Foot position, stairs and the five-second lower — the three ways to make a heel raise harder without more weight.

Eccentric control brakes you

Lowering strength — downhill, decelerating, the last mile — is lost first and is where calves tear.

Both legs get weak

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

Carries load the leg upright

Walking with load trains the calf, foot and hip together in the position running uses.

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.
