Setup

  1. Stand with feet hip-width apart, holding a kettlebell by the horns in a goblet position tucked firmly against your chest.
  2. Pull your shoulder blades back and down to create a stable upper back and 'shelf' for the weight.
  3. Engage your core and fix your gaze forward to maintain a neutral spine and balance.

How to do it

  1. Inhale as you take a controlled step forward, landing softly on the heel then transitioning weight to the midfoot.
  2. Lower your hips vertically until both knees are bent at approximately 90 degrees, with the back knee hovering just above the floor.
  3. Exhale as you drive powerfully through the front midfoot to return to the starting standing position in one fluid motion.
  4. Repeat the movement by stepping forward with the opposite leg, alternating sides for the duration of the set.

Form checklist

  • Keep the front knee tracked directly over the second toe, preventing it from caving inward.
  • Maintain an upright torso; do not let the weight of the kettlebell pull your chest forward or round your shoulders.
  • Ensure your stride is long enough so the front heel stays glued to the floor throughout the descent.
  • Keep your hips square and level, avoiding any tilting or swaying as you step.

Pro tips

  • Focus on 'pushing the floor away' with your front foot to maximize glute and quad recruitment during the ascent.
  • To increase oblique activation, actively resist the kettlebell's tendency to pull your ribcage down, keeping your spine long.

Make it harder

  • Hold the kettlebell in a single-arm rack position to significantly increase the anti-lateral flexion demand on the core.
  • Add a 2-second pause at the bottom of each lunge to eliminate momentum and increase time under tension.
