Banded ankle inversion is a seated strengthening exercise: a resistance band loops around the front of your foot and is anchored to the outside, and you turn the sole of your foot inward against it, then return slowly. It mainly works the tibialis posterior, the muscle whose tendon runs behind the inner ankle bone and helps hold up the arch, so it appears in rehab for posterior tibial tendon problems and as one direction of strength work after an ankle sprain. This page is general education, not a prescription; a physical therapist sets the band strength and range after examining your ankle.

Which muscle does banded inversion target, and why does it matter for the arch?
Banded inversion targets the tibialis posterior, a deep calf muscle whose tendon wraps behind the inner ankle bone and attaches under the arch. It is one of the main active supports of the arch, so when its tendon is irritated or weak, the arch can gradually flatten and the inner ankle can ache.
That pattern is described on the posterior tibial tendonitis page. Early on it often feels like pain and swelling along the inner ankle after walking, and it can be mistaken for a simple sprain. The arch pain in the foot page covers other causes of pain in the same area.
Where does inversion strengthening fit after a rolled ankle?
After a common ankle sprain, therapists usually strengthen the ankle in all directions, with turning the foot outward (eversion) often emphasized; inversion is added carefully because rolling inward is the movement that injured the ligament. It is kept within a pain-free range and progressed as the ligament settles.
Strength is only part of sprain rehab; balance and hopping drills matter just as much before returning to court or field sports. The ankle sprain page and the answer on how long a sprained ankle takes to heal set out the usual stages.
How do you keep the movement in the ankle instead of the hip?
The usual cheat is rolling the whole leg inward from the hip so the foot appears to turn without the ankle doing much. Keep the kneecap pointing at the ceiling, or rest a hand on your thigh to feel it stay still.
- Pointing the toes down hard, which shifts work to the calf; keep the ankle roughly at a right angle.
- Letting the band snap the foot back instead of returning slowly.
- Using a band so heavy that the range shrinks to a twitch.
- Curling the toes to help; they should stay relaxed.
What comes after the band for inner ankle strength?
Once seated band work is easy, therapists usually move to standing exercises that load the tibialis posterior with body weight, because walking and running ask far more of it than a band can.
| Stage | Exercise | Purpose |
|---|---|---|
| Early | Isometric push of the inner foot against the other foot or a wall | Load without movement when the tendon is sore |
| Band | Seated banded inversion, light to moderate band | Strength through range |
| Band, harder | Slower return, heavier band, leg crossed over the other knee | More load and better isolation |
| Standing | Double-leg heel raise holding a ball between the heels | Body-weight load with the heels kept from rolling out |
| Advanced | Single-leg heel raise | Closer to the demands of walking and running |
How to do banded ankle inversion, step by step
Anchor the band
Tie or loop a resistance band to a sturdy table leg or post on the outside of the foot you are training.
Sit and set the foot
Sit on the floor or a chair with the leg straight or crossed over the other knee, and loop the band around the inner side of the forefoot so it pulls the foot outward.
Find the start
Begin with the foot turned slightly outward by the band, ankle at roughly a right angle, toes relaxed.
Turn the sole inward
Breathing out, turn the sole of the foot inward against the band, keeping the ankle at a right angle and the knee and hip still.
Return slowly
Let the foot return to the start over a slow count, then repeat for the number your therapist set.
Stop and get your ankle examined if
- You felt a pop along the inner ankle, or you cannot rise onto your toes on that foot.
- Your arch has visibly flattened over weeks or months, or the inner ankle stays swollen.
- You have diabetes and notice foot numbness, a wound, or changes in foot shape.
- After a sprain, the bone is tender to touch or you could not put weight on the foot.
If you think it is an emergency, call 911.
