Exercise guide

Double High Knee Side Hop

  • Intermediate
  • Compound
  • Timed hold
  • Lower legs

This plyometric movement builds lateral power, cardiovascular endurance, and core stability by combining explosive side-to-side hops with rapid high-knee drives. It effectively targets the lower body while challenging the hip flexors and abdominals through the high-knee phase.

Equipment

  • Body weight

Setup

  1. Stand with your feet hip-width apart and a slight bend in your knees.
  2. Engage your core and keep your chest upright with your arms in a ready position at your sides.
  3. Ensure you have at least 4-5 feet of clear space to your left and right for lateral movement.

How to do it

  1. Push off your outside foot to hop laterally to the side, landing softly on the opposite foot with a slight bend in the knee to absorb impact.
  2. Immediately perform two rapid high-knee drives, bringing each knee up to hip height while pumping your arms in a running motion.
  3. Exhale sharply during the high-knee drives and inhale as you prepare for the next lateral hop.
  4. Repeat the movement by hopping back to the starting side and immediately performing two high-knees again.

Form checklist

  • Land softly on the balls of your feet to protect your joints.
  • Keep your torso upright and avoid leaning forward during the high-knee phase.
  • Drive your knees up to at least hip height for maximum abdominal engagement.
  • Maintain a steady, rhythmic pace without pausing between the hop and the knee drives.

Pro tips

  • Focus on 'quiet landings' to ensure you are using your muscles, not your joints, to decelerate.
  • Coordinate your arm swing with your legs—opposite arm to opposite leg—to increase explosive power and balance.

Make it harder

  • Increase the lateral distance of the hop to further challenge the glutes and lateral power.
  • Hold a light medicine ball at chest height to increase the demand on your core and shoulders.
