Setup

  1. Stand upright facing a step or low platform with your feet hip-width apart.
  2. Keep your arms relaxed at your sides and maintain a tall, neutral posture.
  3. Position yourself approximately one step's distance away from the platform.

How to do it

  1. Step forward with your right foot onto the center of the step while simultaneously swinging both arms forward and up to shoulder height.
  2. Lower your hips into a lunge until your front thigh is nearly parallel to the floor, inhaling during the descent.
  3. Exhale and push powerfully off the step with your right foot to return to the starting position, swinging your arms back down to your sides.
  4. Repeat the movement by stepping forward with your left foot, continuing to alternate sides.

Form checklist

  • Keep your torso upright and avoid leaning forward as you step onto the platform.
  • Ensure your front knee stays aligned with your toes and does not cave inward.
  • Engage your core throughout the movement to maintain balance during the arm swing.
  • Land with your entire foot flat on the step, rather than just the toes or heel.

Pro tips

  • Focus on the mind-muscle connection by squeezing your glutes and abs at the bottom of the lunge to stabilize the swing.
  • Use a controlled, rhythmic tempo to ensure the arm swing assists your momentum rather than throwing you off balance.

Make it harder

  • Increase the height of the step to deepen the lunge and increase the demand on the quadriceps and glutes.
  • Hold light weights or water bottles in each hand to increase the resistance for the deltoids and pectorals.
