Muscles worked

Primary

  • Tibialis

Secondary

  • Calves

Equipment

  • Resistance band

Setup

  1. Sit on the floor with your legs extended straight in front of you.
  2. Loop a resistance band or rope around the ball of your foot, specifically favoring the inner edge.
  3. Hold the ends of the band firmly with both hands, sitting with a tall, neutral spine.

How to do it

  1. Rotate your foot inward (inversion) so the sole of the foot faces toward your other leg.
  2. Pull the band toward your body to bring your toes toward your shin (dorsiflexion) while maintaining the inward rotation.
  3. Exhale as you hold the peak stretch for 20-30 seconds, feeling the tension along the inner calf and ankle.
  4. Slowly release the tension, then switch the band to the other foot and repeat.

Form checklist

  • Keep your knee straight but not hyperextended throughout the stretch.
  • Ensure the rotation occurs at the ankle joint rather than rotating the entire leg from the hip.
  • Maintain a tall posture; avoid rounding your lower back as you pull the band.
  • Keep your toes relaxed rather than curling them tightly.

Pro tips

  • To maximize the stretch, focus on 'scooping' the big toe side of your foot up and back toward your inner shin.
  • Think about creating length from the inner arch of your foot all the way up the back of your tibia.

Make it harder

  • Incorporate PNF stretching: push your foot against the band's resistance for 5 seconds, then relax and pull into a deeper stretch.
  • Perform the stretch while seated on a chair with the leg crossed over the opposite knee to change the angle of pull.
