  • Weight plate

Setup

  1. Position a barbell across your upper traps and unrack it, standing with feet hip-width apart.
  2. Ensure you have clear space approximately 3-4 feet both in front of and behind you.
  3. Engage your core and pull your shoulder blades together to create a stable shelf for the bar.

How to do it

  1. Step forward with one leg into a lunge, inhaling as you lower your hips until both knees are at 90-degree angles.
  2. Exhale and drive forcefully off the front foot to swing that same leg directly into a reverse lunge without touching the floor in the center.
  3. Inhale as you lower into the reverse lunge, then exhale and drive through the stationary foot to return to the starting standing position.
  4. Complete the full forward-backward sequence on one leg before switching sides or alternating.

Form checklist

  • Keep your torso upright throughout the transition to prevent the barbell from shifting forward.
  • Maintain a 'tracks, not a tightrope' stance by keeping feet hip-width apart during the lunges.
  • Ensure the knee of the lead leg tracks in line with your toes, avoiding any inward collapse.
  • Keep your core braced tightly to stabilize the spine against the moving weight.

Pro tips

  • Focus on the stationary leg as an anchor; it should remain rooted while the moving leg acts like a pendulum.
  • To maximize stability, fix your gaze on a stationary point on the floor about 5-10 feet in front of you.
  • Minimize the 'tap' in the middle transition to keep constant tension on the stabilizing glute and quad.

Make it harder

  • Add a 2-second pause at the bottom of both the forward and backward phases of the movement.
  • Increase the speed of the transition through the center to challenge your reactive stability and balance.
