Setup

  1. Stand with feet hip-width apart and step one foot back into a long lunge stance.
  2. Lower your hips until your front thigh is nearly parallel to the floor, keeping the back heel elevated.
  3. Hinge forward at the hips to bring your torso over your front thigh, placing your fingertips on the floor on either side of your front foot.
  4. Ensure your front knee is stacked directly over your ankle and your back leg is fully extended.

How to do it

  1. Inhale and sink deeper into the lunge, feeling a stretch in the back leg hip flexor and tension in the front glute.
  2. Exhale and drive through the front heel to lift the hips slightly, maintaining the forward-leaning 'sprinter' torso angle.
  3. Maintain a slow, controlled tempo (3 seconds down, 1 second up) to maximize time under tension.
  4. Complete all repetitions on one leg before switching to the opposite side.

Form checklist

  • Keep your spine neutral and chest open; avoid rounding your upper back.
  • Ensure the front knee stays aligned with the second toe and does not cave inward.
  • Keep the back leg active and straight by pushing the back heel toward the wall behind you.
  • Distribute 70-80% of your weight through the front heel to prioritize glute engagement.

Pro tips

  • Think about 'pulling' your front hip back while 'pushing' your back hip forward to square the pelvis and intensify the glute stretch.
  • Hover your fingertips an inch off the ground to force your core and stabilizing muscles to work harder.

Make it harder

  • Add a plyometric element by explosively driving the back knee toward the chest into a high-knee jump.
  • Hold a pair of dumbbells at your sides while maintaining the forward torso lean to increase the load on the lower body.
