How to do it

  1. Begin with a box of an appropriate height 1-2 feet in front of you.
  2. Perform a short squat in preparation for jumping, swinging your arms behind you.
  3. Rebound out of this position, extending through the hips, knees, and ankles to jump as high as possible.
  4. Land on the box with the knees bent, absorbing the impact through the legs.

Coaching cues

The two cues IronPack shows on this exercise's card mid-workout:

Logging it

IronPack suggests working in the 3 to 8 rep range, progressing in 1 kg jumps when you own the top of the range. Bodyweight movement: log added weight only, and your records account for your logged bodyweight. Records are tracked automatically at every rep count from 1 to 12. Check your estimated 1RM from any hard set.
