Muscles worked
Setup
- Sit on a flat bench with your legs extended forward.
- Loop a light resistance band around the ball of your working foot.
- Anchor the other end of the band to a stable post or loop it around your opposite foot to create lateral tension pulling your foot outward.
- Cross your working leg over the opposite knee or keep it straight, ensuring the band is taut in the starting position.
How to do it
- Rotate your foot inward (inversion) against the band's resistance, pulling your sole toward the midline of your body.
- Exhale as you reach the end of the range of motion and hold the contraction for one second.
- Inhale as you slowly return the foot to the starting position using a controlled 3-second tempo.
- Perform the desired number of repetitions before switching to the other leg.
Form checklist
- Keep your lower leg and knee completely still; movement should only occur at the ankle joint.
- Avoid curling your toes to compensate; focus on moving the midfoot and heel.
- Maintain constant tension on the band throughout the entire set.
- Ensure the movement is smooth and rhythmic, avoiding jerky motions.
Pro tips
- Think about 'scooping' the arch of your foot upward and inward to maximize the engagement of the posterior tibialis.
- Visualize showing the bottom of your foot to your opposite shin to ensure a full range of motion.
Make it harder
- Increase the resistance by using a thicker band or increasing the distance from the anchor point.
- Add a 3-second isometric hold at the point of maximum contraction.
