Exercise guide

Kettlebell Side Lunge

  • Intermediate
  • Compound
  • Rep-based
  • Lower legs
  • Upper legs

The Kettlebell Side Lunge is a powerful lateral movement that develops lower body strength and hip mobility while specifically targeting the glutes, quads, and adductors. It improves frontal plane stability and functional athleticism by challenging the muscles in a different plane of motion than standard lunges.

Equipment

  • Kettlebell

Setup

  1. Stand with your feet hip-width apart, holding a kettlebell at chest height in a goblet grip (by the horns).
  2. Engage your core and pull your shoulder blades back and down to create a stable shelf for the weight.
  3. Ensure your toes are pointing straight forward and your weight is balanced across your mid-foot.

How to do it

  1. Inhale as you take a wide step to the side, keeping your trailing leg completely straight and both feet flat on the floor.
  2. Hinge your hips back and bend the knee of the stepping leg, lowering your hips until your thigh is nearly parallel to the ground.
  3. Exhale and drive forcefully through the heel and mid-foot of the bent leg to push yourself back to the starting position.
  4. Maintain a controlled 2-second descent (eccentric) and an explosive 1-second return (concentric).

Form checklist

  • Keep the trailing leg locked straight throughout the entire rep.
  • Ensure the knee of the working leg tracks directly over your toes, preventing it from caving inward.
  • Maintain a flat back and upright chest; do not let the kettlebell pull your torso forward.
  • Keep both heels glued to the floor to ensure proper force production and balance.

Pro tips

  • Think about 'sitting back' into your hip rather than just 'stepping out' to maximize glute and hamstring loading.
  • Pause for a split second at the bottom of the movement to eliminate momentum and increase time under tension for the adductors.

Make it harder

  • Hold the kettlebell in a front-rack position on the side of the working leg to increase the demand on your lateral core stabilizers.
  • Perform the movement with a 'floating' trailing foot, where you return to a single-leg balance at the top of each rep.
