Jump Squat

  • Intermediate
  • Compound
  • Timed hold
  • Lower legs
  • Upper legs

The jump squat is a high-intensity plyometric exercise that builds explosive power and lower-body strength by combining a traditional squat with a vertical leap. It primarily targets the quadriceps and glutes while significantly increasing heart rate and athletic performance.

Setup

  1. Stand with your feet shoulder-width apart and toes pointed slightly outward.
  2. Engage your core and maintain a neutral spine with your chest lifted.
  3. Position your arms at your sides or held together in front of your chest.

How to do it

  1. Inhale as you lower your hips back and down into a squat until your thighs are parallel to the floor.
  2. Exhale forcefully and drive through the balls of your feet to explode vertically as high as possible.
  3. Swing your arms upward as you jump to generate momentum and maintain balance.
  4. Land softly on the balls of your feet, immediately absorbing the impact by transitioning smoothly into the next squat.

Form checklist

  • Land with 'soft knees' to protect your joints from impact.
  • Keep your knees tracking in line with your toes; do not let them cave inward.
  • Maintain an upright torso and avoid rounding your lower back.
  • Ensure your heels stay on the ground during the initial squat phase before the jump.

Pro tips

  • Focus on 'triple extension'—fully extending your hips, knees, and ankles simultaneously at the peak of the jump.
  • Minimize the time spent on the ground between reps to maximize the stretch-shortening cycle of the muscles.

Make it harder

  • Perform 'Tuck Jump Squats' by pulling your knees toward your chest at the peak of the jump.
  • Hold a light medicine ball or wear a weighted vest to increase the resistance and power requirement.
