Plyo Sit Squat Wall

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

This explosive variation of the wall sit combines isometric tension with plyometric power to develop lower body strength and reactive force. It specifically targets the quadriceps and glutes while engaging the calves for the vertical drive.

  • Body weight

Setup

  1. Stand with your back against a flat wall and feet shoulder-width apart, roughly 18-24 inches away from the base.
  2. Slide your back down the wall until your thighs are parallel to the floor, creating 90-degree angles at the hips and knees.
  3. Press your entire spine firmly against the wall and keep your arms at your sides or held in front of your chest.

How to do it

  1. From the seated position, explosively drive through the balls of your feet to jump vertically as high as possible, pushing slightly away from the wall.
  2. Exhale forcefully during the jump and swing your arms upward to assist with vertical momentum.
  3. Land softly on the balls of your feet with knees slightly bent to absorb the impact, then immediately step back to the wall.
  4. Slide back down into the wall sit under control, inhaling as you reset for the next repetition.

Form checklist

  • Keep your knees tracked over your toes and prevent them from caving inward.
  • Maintain a flat back against the wall during the isometric sitting phase.
  • Ensure a soft, quiet landing by rolling from the balls of your feet to your heels.
  • Maintain a full 90-degree depth during the sit to maximize quad recruitment.

Pro tips

  • Focus on a rapid transition from the static hold to the jump to maximize the stretch-shortening cycle of the muscles.
  • Squeeze your glutes at the peak of the jump to ensure full hip extension and maximum power output.

Make it harder

  • Increase the isometric hold time to 5-10 seconds between each jump to significantly increase muscular fatigue.
  • Hold a medicine ball or dumbbell at chest height to add external resistance to the jump.
