Exercise guide

Dumbbell Side Lunge

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

The dumbbell side lunge is a powerful lateral movement that builds lower body strength while improving hip mobility and targeting the adductors. It challenges stability and strengthens the glutes and quads through a functional plane of motion often missed in traditional forward lunges.

Equipment

  • Dumbbell

Setup

  1. Stand with your feet hip-width apart, holding a single dumbbell vertically against your chest with both hands in a goblet grip.
  2. Engage your core and pull your shoulder blades back and down to maintain a tall, upright posture.
  3. Ensure you have sufficient clear space to your sides to perform a wide lateral step.

How to do it

  1. Take a wide step out to the side, keeping your toes pointed forward and your trailing leg completely straight.
  2. Inhale as you shift your weight onto the stepping leg, hinging your hips back and bending the knee as if sitting into a chair.
  3. Lower your hips until your working thigh is nearly parallel to the floor, keeping your chest lifted.
  4. Exhale and drive powerfully through the heel of the bent leg to push yourself back to the starting position in one fluid motion.

Form checklist

  • Keep the heel of the working leg firmly planted on the floor at all times.
  • Ensure the knee of the working leg tracks in line with your toes, not collapsing inward.
  • Maintain a straight trailing leg to maximize the stretch and engagement of the adductors.
  • Keep your spine neutral and avoid rounding your shoulders forward as you descend.

Pro tips

  • Focus on 'sitting back' into the hip of the working leg rather than just pushing the knee forward to maximize glute activation.
  • Pause for one second at the bottom of the movement to emphasize the eccentric control and the stretch in the inner thigh.

Make it harder

  • Hold a dumbbell in each hand and frame the working knee with the weights at the bottom of the movement.
  • Perform the exercise by returning to a single-leg balance position instead of touching the foot back down to the floor.
