Side Squat

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

The side squat is a powerful lateral movement that builds unilateral lower-body strength while significantly improving hip mobility and adductor flexibility. It targets the glutes and quads of the working leg while providing a deep stretch to the inner thigh of the trailing leg.

Setup

  1. Stand with your feet significantly wider than shoulder-width apart, with toes pointing forward or slightly outward.
  2. Engage your core and hold your hands in front of your chest for balance.
  3. Distribute your weight evenly across both feet to establish a stable base.

How to do it

  1. Inhale as you shift your weight to one side, hinging at the hips and bending the knee while keeping the opposite leg completely straight.
  2. Lower your hips as deep as your mobility allows, ensuring the heel of the working foot stays firmly planted on the floor.
  3. Exhale and drive through the heel of the bent leg to push yourself back to the starting center position.
  4. Maintain a controlled tempo, taking 2 seconds to descend and 1 second to return to the start.

Form checklist

  • Keep the chest lifted and avoid rounding the spine or leaning too far forward.
  • Ensure the knee of the working leg tracks directly over the toes, preventing it from caving inward.
  • Keep the trailing leg fully extended with the foot remaining flat on the ground.
  • Keep your weight centered in the heel and midfoot of the working leg.

Pro tips

  • Focus on 'sitting back' into the hip of the working side rather than just pushing the knee forward to maximize glute engagement.
  • Actively pull yourself down into the stretch using your hip flexors to improve active range of motion.
  • At the bottom of the movement, pause briefly to feel the stretch in the adductors before driving upward.

Make it harder

  • Hold a kettlebell or dumbbell in the goblet position to increase the load on the quadriceps and core.
  • Incorporate a 3-second isometric pause at the bottom of each repetition to increase time under tension.
