Does Band Ankle Inversion work the tibialis posterior?

Yes, resisted inversion is one of the standard ways to load it. In an MRI study of five healthy adults, open-chain resisted foot supination, the movement closest to this exercise, raised tibialis posterior activity by about 26%, while a closed-chain foot adduction drill raised it by about 50%.

Should I do inversion exercises after rolling my ankle?

Yes, once the ankle tolerates it, because a sprain weakens the ankle in every direction and rehab programs train all four. Start with pain-free isometric holds or a partial range, since turning the foot fully inward stretches the healing ligaments on the outside of the ankle, and build to the full movement as pain and swelling settle.

How many sets and reps should I do?

Rehab and prehab programs commonly use 2 to 3 sets of 10 to 20 slow reps per foot, a few times a week. Choose a band light enough that you can finish every rep with the knee and thigh still, and move up a band when the last reps feel easy.

How is this different from Band Ankle Eversion?

It is the same seated setup with the band anchored on the other side. Here the anchor sits outside the foot and you turn the sole inward, while in Band Ankle Eversion the anchor sits inside the foot and you turn the sole outward, so most ankle programs pair the two.

Can this exercise help with flat feet or shin splints?

It can be one part of a plan, but not a fix on its own. The tibialis posterior helps support the inner arch, so clinicians often include resisted inversion for inner-ankle and inner-shin complaints alongside calf raises, footwear or orthotic changes and sensible running load, and arch pain that keeps getting worse needs a professional assessment.

Band Ankle Inversion

What Is the Band Ankle Inversion?

Band Ankle Inversion is an isolation exercise that primarily targets the lower legs, specifically the muscles that turn the sole of the foot inward. It is a beginner-level movement done seated, with a resistance band looped around the forefoot and anchored low on the outside of the working foot, so the band pulls the foot outward and you turn it back in against that pull.

The main mover is the tibialis posterior, a deep calf muscle whose tendon runs behind the inner ankle bone and helps hold up the inner arch of the foot. The tibialis anterior at the front of the shin assists, especially while the toes stay slightly lifted. Because few gym exercises turn the foot inward against resistance, physical therapists use resisted inversion to rebuild ankle strength after a sprain or a spell in a boot, and as a staple for irritated posterior tibial tendons and weakness on the inner side of the ankle.

It is the mirror image of Band Ankle Eversion, which uses the same seated setup with the anchor on the inside of the foot, and the two are usually trained together. Add Band Seated Tibialis Raise and Band Seated Calf Raise and you have the standard four-direction ankle band routine. It fits at the end of a lower-body session, in a warm-up for running and court sports, or as a stand-alone rehab block, and it works best with a light band and higher reps rather than heavy resistance.

Runners, field and court athletes with a history of rolled ankles, people returning from foot or ankle surgery and older adults working on foot control all benefit. The movement is small, so attention matters: the foot should pivot at the ankle while the knee and thigh stay still, because turning the whole leg from the hip is the easiest way to fake the range. If moving against the band hurts, start with gentle Ankle Circles or with pain-free isometric holds against the band before adding movement.

Instructions

Sit tall on a sturdy chair with both feet on the floor and your hands resting on your thighs.
Loop a light resistance band around the forefoot of the working foot and anchor the other end low to a rack upright or another sturdy post on the outside of that foot, roughly level with it.
Slide the working foot forward so the knee is a little straighter than 90 degrees, rest the heel on the floor and let the toes lift slightly.
Shift the chair away from the anchor until the band is taut and gently pulls the forefoot outward. This is the start position.
Keeping the heel planted and the knee pointing forward, turn the sole of the foot inward, sweeping the toes toward your other foot against the band.
Pause briefly at the end of your pain-free range.
Return slowly to the start over about two seconds, letting the band draw the foot outward without snapping it back.
Complete your reps, then reposition so the anchor sits on the outside of the other foot and repeat.

Common Mistakes

Turning the leg from the hip
Letting the knee swing inward and the thigh rotate moves the foot without the ankle doing the work, so keep the knee pointing forward and pivot only at the ankle.
Sliding or lifting the heel
The heel stays planted as the pivot point, because dragging the whole foot across the floor or lifting the heel turns the drill into a leg movement.
Letting the band snap back
Rushing the return lets the band yank the foot outward and skips the controlled lowering, so take about two seconds to come back to the start.
Starting with a slack band
If the band is loose at the start, the first part of each rep has no resistance, so sit far enough from the anchor that the band is already pulling the forefoot outward.
Anchoring on the wrong side
An anchor on the inside of the foot resists turning the foot outward instead, so the band must come from the outside of the working foot for this exercise.

Injuries

Band Ankle Inversion is a low risk exercise when performed with proper technique. The load is light, the body is supported by the chair and only the ankle moves, so the main things to watch are the tendon behind the inner ankle bone and, after a sprain, the ligaments on the outside of the ankle, which are stretched as the sole turns fully inward.

Keep the movement slow in both directions and stay within a pain-free range. After a recent rolled ankle, begin with isometric holds, pressing the foot inward against the band without moving it, or with a partial range, and work toward the full movement as pain and swelling settle. Check that the band sits securely around the forefoot and the anchor is solid before each set, since a band that slips off can snap back toward the foot or face.

To progress, use a heavier band, slow the return to three seconds or add a pause at the end of the range, then move on to standing work such as Bodyweight Single-Leg Calf Raise and balance drills like Wobble Board Single-Leg Balance. Stop if you feel sharp pain behind the inner ankle bone or along the inner shin, pain that lingers into the next day, new swelling, or the ankle giving way. Inner ankle pain with an arch that is flattening over time should be assessed by a clinician rather than trained through.
