Equipment

  • Resistance band

Setup

  1. Anchor a resistance band to a low, sturdy point behind you and loop the other end around the front of your ankle, positioned just below the ankle bones (malleoli).
  2. Place your front foot firmly on a flat bench, ensuring there is significant tension in the band pulling your ankle backward.
  3. Step your trailing leg back into a long lunge stance on the floor for stability.
  4. Keep your torso upright and hold onto a rack or wall for balance if necessary.

How to do it

  1. Inhale and slowly drive your front knee forward as far past your toes as possible while keeping your heel glued to the bench.
  2. Hold the end range for 2 seconds, feeling the band pull the ankle joint backward as the knee moves forward.
  3. Exhale and push through the midfoot of the front leg to return to the starting upright lunge position.
  4. Perform the movement with a controlled 3-second descent and a 1-second return.

Form checklist

  • Keep the front heel firmly planted; do not let it lift as the knee moves forward.
  • Ensure the front knee tracks directly over the second toe, avoiding any inward collapse.
  • Maintain a low band position on the ankle to ensure the force is applied to the talus bone, not the shin.
  • Keep your hips square and your core braced to prevent lower back arching.

Pro tips

  • Think of the band as 'clearing' the ankle joint, allowing your tibia to slide forward more freely.
  • Drive your weight into the front heel to maximize glute activation during the return phase.
  • Focus on a deep, active stretch in the Achilles and calf at the bottom of the movement.

Make it harder

  • Hold a kettlebell or dumbbell in the 'goblet' position to add load and increase the stretch intensity.
  • Increase the resistance of the band or move the bench further from the anchor point to create more posterior pull.
