Exercise guide

Side Lunge Stretch

  • Beginner
  • Compound
  • Timed hold
  • Lower legs
  • Upper legs

This lateral movement improves hip mobility and flexibility in the adductors and glutes while building stability in the lower body. It is highly effective for opening up the hips and preparing the legs for explosive lateral movements.

Equipment

  • Body weight

Setup

  1. Stand with your feet in a wide stance, roughly double shoulder-width apart.
  2. Point your toes forward or slightly outward, keeping your chest tall and core braced.
  3. Distribute your weight evenly across both feet with hands held at your chest for balance.

How to do it

  1. Shift your weight to one side by hinging at the hips and bending the knee, while keeping the opposite leg completely straight.
  2. Lower your hips as far as your mobility allows, exhaling as you descend into the stretch.
  3. Hold the bottom position for 2-3 seconds to feel the stretch in the inner thigh of the straight leg.
  4. Inhale as you drive through the heel of the bent leg to return to the wide standing starting position.

Form checklist

  • Keep the heel of the working leg firmly planted on the ground.
  • Ensure the knee of the bent leg tracks in line with the toes, not caving inward.
  • Maintain a flat back and proud chest throughout the entire range of motion.
  • Keep the non-working leg fully extended with the foot flat on the floor.

Pro tips

  • To maximize the adductor stretch, rotate the foot of the straight leg so the toes point toward the ceiling as you descend.
  • Think about 'sitting back' into your hip rather than just pushing your knee forward to better engage the glutes and protect the joint.

Make it harder

  • Perform the movement dynamically by stepping into the lunge from a narrow stance and pushing back to center in one fluid motion.
  • Hold a light weight at chest height in a goblet position to increase the demand on your core and leg stabilizers.
