Exercise guide

Dumbbell Single Leg Squat

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

This advanced unilateral exercise builds exceptional lower body strength and stability by isolating one leg, placing intense demand on the quadriceps and glutes. It requires significant core control and ankle mobility to maintain balance throughout the full range of motion.

Equipment

  • Dumbbell

Setup

  1. Stand tall holding a single dumbbell at chest height with both hands (goblet grip).
  2. Shift your weight onto the working leg and extend the opposite leg straight out in front of you, hovering just off the floor.
  3. Engage your core and fix your gaze on a point 5-10 feet ahead of you for balance.

How to do it

  1. Inhale and slowly lower your hips back and down as if sitting into a chair, keeping the non-working leg elevated and straight.
  2. Descend until your working thigh is at least parallel to the floor, ensuring your heel stays glued to the ground.
  3. Exhale and drive through the mid-foot of the standing leg to return to the starting position with control.
  4. Maintain a controlled 3-second eccentric (lowering) phase and a 1-second concentric (rising) phase.

Form checklist

  • Keep the heel of the working foot firmly planted; do not let it lift.
  • Ensure the knee tracks directly over the toes and does not cave inward.
  • Maintain a proud chest and avoid excessive rounding of the spine.
  • Keep the non-working leg fully extended to prevent it from touching the floor.

Pro tips

  • Hold the dumbbell slightly away from your chest to act as a counterweight, which helps keep your torso more upright.
  • Focus on 'gripping' the floor with your toes to create a stable arch and improve balance.
  • Squeeze the glute of the working leg at the top of the movement for maximum peak contraction.

Make it harder

  • Perform the movement standing on a small box or bench to allow for a deeper range of motion.
  • Incorporate a 2-second pause at the bottom of the squat to eliminate momentum.
