Box Jump — CrossFit Technique Guide
BB
By Borja Bes — CrossFit Athlete & Hyrox Finisher
The box jump is a plyometric movement that develops explosive lower-body power, coordination, and the ability to absorb impact safely. In CrossFit, box jumps are performed to standard heights of 24 inches (men) and 20 inches (women) and require the athlete to reach full hip and knee extension (standing tall) at the top of the box. Box jumps appear in benchmark workouts and Hero WODs as a power-based conditioning tool. Step-downs between reps are encouraged for safety — the Achilles tendon ruptures that have occurred in CrossFit are almost always from rebounding (jumping back down rapidly).
Quick answer
Box Jump is best used when the workout goal matches its main demand: bodyweight capacity, clean mechanics, and scalable intensity.

Best For, Avoid If, and Scaling
| Best for | Bodyweight WODs, skill practice, and athletes who can keep box jump mechanics consistent under fatigue. |
|---|---|
| Avoid if | Pain changes your movement pattern, fatigue makes reps sloppy, or the workout asks for a standard you cannot repeat safely. |
| Scaling | Step-ups (step one foot, then the other), lower box height, box jumps with step-down. |
How to Do the Box Jump
1
Stand facing the box, feet hip-width apart, arms at sides.
2
Dip into a quarter squat and swing arms back, then explosively extend hips, knees, and ankles.
3
Pull knees up and land softly on the box with both feet, hips above knees.
4
Stand to full hip and knee extension at the top.
5
Step down one foot at a time (recommended) or jump down with control.
6
Reset and repeat.
Common Mistakes
✕
Not reaching full extension at the top — a common shortcut; judges will no-rep it.
✕
Rebounding off the box — jumping down rapidly increases Achilles tendon rupture risk significantly.
✕
Landing with excessive forward lean or soft knees that collapse inward.
Coaching Tips
✓
Step-downs can be a controlled alternative when rebounding is not appropriate for your experience or current capacity.
✓
Box height should allow a two-inch clearance — if you are barely making it, drop the height.
Scaling Options
Easier / Beginner
Step-ups (step one foot, then the other), lower box height, box jumps with step-down.
Harder / Advanced
Higher box, weighted box jumps (light vest), box jump overs.

Frequently Asked Questions
Should I rebound or step down from box jumps in CrossFit?
Step-downs reduce repeated rebound demand and are a sensible choice for many training sessions. Rebounding requires experience, consistent landing mechanics and appropriate volume; ask a qualified coach when unsure.
