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 the exercise in the video above… all you need is a step!

  1. 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

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

  3. 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?

    1. 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.



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