Exercise guide

Deep Sumo Squat Pulse

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

This high-tension variation targets the glutes, adductors, and quads by maintaining constant time under tension in the deepest part of the squat. It is highly effective for building lower-body endurance and improving hip mobility through a wide-stance range of motion.

Setup

  1. Stand with your feet significantly wider than shoulder-width apart.
  2. Turn your toes outward at approximately a 45-degree angle.
  3. Keep your chest upright and clasp your hands in front of your chest for balance.
  4. Engage your core to maintain a neutral spine before beginning the descent.

How to do it

  1. Inhale as you lower your hips back and down until your thighs are at least parallel to the floor.
  2. From the bottom of the movement, rise up only 2-3 inches, then immediately lower back down to the deep starting position.
  3. Exhale small, sharp breaths with each pulse while maintaining a rhythmic, controlled tempo.
  4. Stay in this bottom range for the duration of the set, never standing up fully until the set is complete.

Form checklist

  • Keep your knees pushed out so they track directly over your toes, avoiding internal collapse.
  • Maintain a proud chest and avoid leaning too far forward at the hips.
  • Keep your weight distributed through your heels and midfoot to maximize glute recruitment.
  • Ensure the movement is a controlled muscular contraction rather than a momentum-based bounce.

Pro tips

  • Imagine trying to 'spread the floor' apart with your feet to further engage the lateral glutes and adductors.
  • Focus on a 'mind-muscle connection' by squeezing your glutes hard at the bottom of every pulse.

Make it harder

  • Hold a dumbbell or kettlebell in a goblet position at chest height to add external resistance.
  • Perform the pulses while slightly lifting your heels off the floor to significantly increase calf and quad demand.
