Demo: Exercise Demo

Sets

3

Reps

8-10 per side

Rest

1:15

Contraindications

Same knee demands as bodyweight version, amplified by load — control the box height to your strength level.

Setup

Hold a dumbbell in each hand at the sides. Stand facing a knee-height box.

Execution

  1. 1Drive through the working foot, keeping the dumbbells over mid-foot
  2. 2Avoid pushing off the back leg
  3. 3Stand to full extension at the top
  4. 4Control the descent
  5. 5Alternate legs or complete all reps per side

Key cues

  • Load stays over the mid-foot
  • Drive with the working leg only
  • Stand tall at the top
  • Control the way down
  • Keep the chest up throughout

Common faults

  • Dumbbells swinging, shifting the load off mid-foot
  • Pushing off the back leg
  • Box too high for controlled loading
  • Knee caving inward
  • Rushing reps for momentum

Tweaks

  • Hold a single dumbbell for unilateral core challenge
  • Try goblet-style holding for more upright torso
  • Increase box height once strength allows
