How to Perform

Stand tall holding a medicine ball pressed against your chest, keeping the core tight and shoulders back. Ensure feet are hip-width apart and look straight ahead before initiating the movement.

  1. Step forward with one leg, sinking the hips down toward the floor while maintaining an upright torso.
  2. Lower until the front thigh is parallel and the back knee hovers above the floor (90/90 degree angles).
  3. Drive through the heel of the front foot to push back to the starting standing position.
  4. Bring the forward foot back to meet the rear foot.
  5. Alternate the leading leg and repeat for the desired number of repetitions.

Coaching Tips

Form Cues

  • Torso upright
  • Knee tracks over foot
  • Drive through heel
  • Maintain chest position
  • Lead with hips

Breathing

Inhale as you descend into the lunge; exhale forcefully as you drive back up to the starting position. Brace the core throughout the movement.

Tempo

2-0-1

Range of Motion

Lower the body until the front thigh is parallel to the ground and the back knee is just above or lightly touches the floor.

Safety

Safety Notes

  • Avoid collapsing the knee past the toes to protect the joint.
  • If pain occurs in the knees, reduce the depth of the lunge.
  • Ensure a stable landing before starting the descent.

Spotting

Not recommended. Focus on controlling the movement and use a lighter ball if stability is compromised.

Common Mistakes

  • Front knee caving inward
  • Leaning torso too far forward
  • Not reaching 90-degree angles
  • Allowing the medicine ball to drop

When to Avoid

  • Acute knee pain or injury
  • Significant balance deficits
  • Recent lower back injury

Flexibility Needed

  • Adequate hip flexor mobility in the trailing leg
  • Good ankle dorsiflexion in the front leg

Build Up First

  • Mastery of the bodyweight lunge movement pattern
  • Basic core bracing competency
