Exercise guide

Star Squat

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

The Star Squat is an explosive, full-body plyometric exercise that builds lower-body power and shoulder mobility by transitioning from a deep squat into a mid-air 'star' extension. It effectively targets the entire posterior chain and quadriceps while utilizing the deltoids for the outward arm reach.

Setup

  1. Stand with your feet hip-width apart and your arms relaxed at your sides.
  2. Engage your core and maintain a neutral spine with your chest lifted.
  3. Position your weight evenly across your feet, focusing on the mid-foot and heels.

How to do it

  1. Inhale as you lower into a deep squat, reaching your hands down toward your outer ankles.
  2. Exhale forcefully as you explode upward into a jump, pushing through the balls of your feet to engage the calves.
  3. While in mid-air, simultaneously extend your arms and legs out to the sides to form a 'star' shape.
  4. Quickly pull your limbs back toward the midline and land softly on the balls of your feet, immediately absorbing the impact by descending into the next squat.

Form checklist

  • Land softly with knees slightly bent to protect your joints.
  • Keep your chest up and avoid rounding your lower back during the squat phase.
  • Ensure your knees track over your toes and do not cave inward (valgus) during takeoff or landing.
  • Fully extend your elbows and knees at the peak of the jump to maximize muscle activation.

Pro tips

  • Focus on 'snapping' your limbs back to the center quickly after the peak of the jump to ensure a stable and controlled landing.
  • Visualize reaching for the corners of the room to maximize the engagement of the lateral deltoids and hip abductors.
  • Maintain a rhythmic tempo to turn this into a high-intensity cardiovascular challenge.

Make it harder

  • Minimize ground contact time by exploding into the next rep as soon as your feet touch the floor.
  • Hold light dumbbells in each hand to increase the resistance on the deltoids and lower body.
