Tibialis Posterior Strength Exercise: Anytime Anywhere!

A Twitter follower of mine just asked me for a simple exercise to target the small but important Tibialis Posterior muscle of the lower leg.

While I’ve already uploaded a video showing my favourite Tibialis Posterior Stretch, it’s important to also build strength in this often weak, and sometimes dysfunctional muscle.

Try this… all you need is a step!:

  • James,
    Great video and explanation of how to strengthen the tibialis posterior. I’m definitely going to pass along your videos to some of my patients.

  • James, After going through a tibial stress fracture and returning to my normal routine I have encountered what feels similar to the pains I had prior to taking time off. It isn’t constant but very random at the beginning of my runs. I would describe it as a ‘phantom’ pain at the injury site. What is your experience with this? I have read similar experiences online

  • Great idea for an exercise – perhaps the eccentric component is useful in tendinopathy of tin post, not sure if this has been studied.

  • Hi James,
    good video and exercise. My only concern is regarding a tib post tendinopathy. A lot of the time it can be a compressive tendinopathy, especially when too much dorsiflexion is applied. Maybe limit the ROM or performing the exercise on a flat ground for this type of circumstance? Any thoughts?

    • Hi Dan,

      Great point, and nice adaptation for the exercise. Performing the exercise on flat ground, or down into a very small amount of dorsiflexion would certainly help avoid excessive compression.



  • Hello, could you please tell me do this works for peroneal tendonitis. thanks
