Tibialis posterior holds the arch

This tendon supports the arch on every step. When it tires the arch drops and the inner shin takes the strain.

Navicular drop

How far the arch drops under load is one of the few repeatable risk factors for shin pain — and it responds to foot and calf training.

Calf strength lowers tibial load

A stronger calf absorbs force that would otherwise pass through the tibia. Strengthening it is shin protection, not just calf training.

How to run it

  1. The shin muscles brake the foot on every landing. Weak there, and the bone takes the shock instead.
  2. Tibialis posterior holds the arch; tibialis anterior lowers the foot. Both get trained here.
  3. A hip that lets the pelvis drop sends more load down the shin — that is why hip work is in this phase.
  4. Burning along the front or inside of the shin during the set is expected. Point tenderness on the bone afterwards is not.
