Weighted Sissy Squat

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

The Weighted Sissy Squat is an advanced quad-dominant movement that emphasizes the rectus femoris by placing the quadriceps under extreme stretch. By leaning back and keeping the hips extended, you shift the entire load onto the knee extensors for maximum hypertrophy.

Setup

  1. Stand with feet shoulder-width apart, holding a weight plate firmly against your chest with one arm.
  2. Place your free hand on the top of an incline bench or a sturdy upright for balance.
  3. Lift your heels slightly off the floor, putting your weight on the balls of your feet.
  4. Engage your core and squeeze your glutes to create a straight line from your knees to your shoulders.

How to do it

  1. Inhale and begin the movement by pushing your knees forward and down toward the floor while leaning your torso backward.
  2. Maintain a rigid straight line from your knees to your head; do not allow your hips to hinge or 'sit' back.
  3. Lower yourself until your knees are a few inches from the floor or you reach the limit of your quad flexibility.
  4. Exhale and drive through the balls of your feet to return to the starting position, keeping the tension on the quads throughout the ascent.

Form checklist

  • Keep hips fully extended throughout the entire range of motion.
  • Maintain a neutral spine and avoid arching the lower back excessively.
  • Ensure the movement is controlled; avoid 'dropping' into the bottom position.
  • Keep your weight centered on the balls of your feet, not your toes.
  • Use the bench only for balance, not to pull yourself up.

Pro tips

  • Focus on the mind-muscle connection by imagining your quads stretching like a rubber band on the way down.
  • Squeeze your glutes as hard as possible to prevent hip flexion, which is the most common way to 'cheat' this movement.
  • Pause for a split second at the bottom of the rep to maximize the loaded stretch on the rectus femoris.

Make it harder

  • Implement a 4-second eccentric (lowering) phase to increase time under tension.
  • Perform 1.5 reps by going all the way down, coming halfway up, going back down, and then standing fully.
