Exercise guide

Dumbbell Single Leg Split Squat With Low Box

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

The dumbbell single-leg split squat with a low box targets the glutes and quads while improving unilateral stability and hip mobility. Using a low box reduces the balance requirement compared to a high bench, allowing for heavier loading and better focus on muscle recruitment.

Setup

  1. Stand approximately two feet in front of a low box or step, holding a dumbbell in each hand at your sides.
  2. Place the top of your rear foot on the box, ensuring your front foot is positioned far enough forward to allow a deep squat.
  3. Engage your core, pull your shoulders back, and shift your weight primarily onto the front leg.

How to do it

  1. Inhale and lower your hips by bending at the front knee and hip, maintaining a slight forward torso lean.
  2. Continue the descent until your front thigh is at least parallel to the floor, keeping your front knee aligned with your toes.
  3. Exhale and drive through the mid-foot of your front leg to return to the starting position.
  4. Perform the movement with a controlled 3-second eccentric (lowering) phase and a 1-second concentric (rising) phase.

Form checklist

  • Keep the front heel firmly planted on the ground at all times.
  • Avoid letting the front knee cave inward; keep it tracking over your toes.
  • Maintain a neutral spine and avoid excessive arching in the lower back.
  • Ensure the rear leg is used only for balance, not for pushing upward.

Pro tips

  • Think of the rear leg as a 'kickstand'—80-90% of your weight should remain on the front leg throughout the set.
  • To maximize glute engagement, hinge slightly more at the hips while keeping your chest up.

Make it harder

  • Add a 2-second pause at the bottom of each rep to increase time under tension.
  • Hold a single dumbbell in the hand opposite to the working leg (contralateral) to increase core and hip stabilizer demands.
