Hopping Knee Drive

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

The Hopping Knee Drive is a dynamic, explosive movement that combines a reverse lunge with a powerful jump to build lower body power and cardiovascular endurance. It effectively targets the quadriceps and calves while requiring significant core and upper body stabilization to maintain balance.

Equipment

  • Body weight

Setup

  1. Stand with your feet hip-width apart, core engaged, and chest tall.
  2. Step your right foot back into a shallow reverse lunge, keeping your weight centered over the left mid-foot.
  3. Position your arms in a 'sprinter' stance with the left arm forward and right arm back to prepare for momentum.

How to do it

  1. Drive your right knee forward and upward toward your chest with explosive force while pushing off the left foot to perform a small hop.
  2. Vigorously pump your arms in a running motion, engaging the chest and shoulders to generate upward momentum.
  3. Exhale forcefully during the knee drive and hop, then inhale as you land softly on the ball of the left foot.
  4. Immediately return the right foot to the starting lunge position and repeat the movement, alternating legs after each rep or completing a set per side.

Form checklist

  • Keep your torso upright and avoid leaning too far forward or rounding your back.
  • Land softly on the mid-foot to absorb impact and protect your joints.
  • Drive the knee high to maximize hip flexor and lower abdominal recruitment.
  • Maintain a steady, rhythmic pace while keeping your core braced for stability.

Pro tips

  • Focus on 'triple extension'—fully extending the ankle, knee, and hip of the standing leg—to maximize power output.
  • Keep your gaze fixed on a point in front of you to help maintain balance during the flight phase.

Make it harder

  • Increase the depth of the initial lunge into a full reverse lunge to increase the range of motion and muscle recruitment.
  • Hold a light pair of dumbbells to increase the resistance on the legs and the demand on the shoulders and chest during the arm drive.
