Muscles worked

Primary

  • Calves

Secondary

  • Glutes
  • Hamstrings
  • Quadriceps

Equipment

  • Resistance band

Setup

  1. Sit on a flat bench with your legs extended forward.
  2. Loop a light resistance band around the ball of your working foot.
  3. 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.
  4. 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

  1. Rotate your foot inward (inversion) against the band's resistance, pulling your sole toward the midline of your body.
  2. Exhale as you reach the end of the range of motion and hold the contraction for one second.
  3. Inhale as you slowly return the foot to the starting position using a controlled 3-second tempo.
  4. 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.
