Split Squats

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

The split squat is a foundational unilateral movement that builds lower body strength and stability while correcting muscle imbalances. It primarily targets the quadriceps and glutes through a deep range of motion while challenging core stability.

Equipment

  • Body weight

Setup

  1. Stand with your feet hip-width apart to maintain a stable base of support.
  2. Take a large step forward with one leg, keeping your back heel lifted off the floor.
  3. Ensure your hips are square to the front and your torso is upright with your core engaged.

How to do it

  1. Inhale and lower your hips straight down by bending both knees until your back knee is just above the floor.
  2. Keep your front knee tracked over your mid-foot, ensuring it does not cave inward.
  3. Exhale and drive through your front heel to return to the starting position without locking out the front knee.
  4. Maintain a controlled 2-second descent and a powerful 1-second ascent.

Form checklist

  • Keep your front knee aligned with your second toe throughout the movement.
  • Maintain a neutral spine and avoid excessive arching in the lower back.
  • Ensure the back knee travels straight down toward the floor rather than forward.
  • Keep your weight primarily in the heel and mid-foot of the front leg.

Pro tips

  • Focus on 'pushing the floor away' with your front heel to maximize glute and quad recruitment.
  • Lean your torso slightly forward (about 15 degrees) to shift more emphasis onto the glutes while maintaining a flat back.
  • Imagine your hips are on a vertical track, moving straight up and down rather than shifting forward and back.

Make it harder

  • Add a 3-second pause at the bottom of each rep to increase time under tension and stability demands.
  • Perform the movement with a 4-second eccentric (lowering) phase to maximize muscle fiber recruitment.
