Box Jumps
Jump, land soft, stand tall. Box jumps build explosive power when height and volume stay honest—and they punish ego heights fast.
Quick answer: Two feet on, quiet landing, stand to extension when required. Choose a height you can repeat safely. 5mm sleeves ($49.00) keep knees warm on volume days; step down when impact adds up.
Why Box Jumps Are Programmed
Explosive power
Train triple extension in a simple, measurable way.
Coordination under fatigue
Common in WODs paired with barbell or gymnastic work.
Scalable
Lower the box or switch to step-ups without losing the session intent.
How to Box Jump
Set Feet roughly hip width, eyes on the landing zone, arms ready to swing.
Load Quick dip—do not turn it into a deep squat every rep unless teaching.
Jump Extend hips, knees, ankles; swing arms; travel up and slightly forward.
Land Full foot on the box, quiet knees, chest up.
Finish / exit Stand to extension if required; step down for high-rep pieces.
Jump vs Step-Up
| Box jump | Step-up | |
|---|---|---|
| Stimulus | Explosive power | Unilateral grind / lower impact |
| Risk | Higher if height is ego-driven | Lower impact |
| Example | Many Open-style WODs | Chad (1,000 step-ups) |

What is a box jump?
A box jump is a two-foot jump onto a box, landing in a squat stance and usually standing to full extension to finish the rep (confirm workout standards).
Box jump vs step-up?
Jumps train explosive power. Step-ups reduce impact and appear in workouts like Chad. Use the movement that is written—or scale jumps to step-ups when needed for safety.
How high should the box be?
High enough to challenge but low enough for safe landings. Ego height that produces stomping or hand assistance is counterproductive.
Soft vs sticking landings?
Land quietly with bent knees, full foot on the box. Stand to extension if the standard requires it. Rebound only when the workout and your joints allow.
Knee sleeves for box jumps?
Helpful for warm knees and high-volume sessions. 5mm ($49.00) is popular for jumping; 7mm ($55.00) if the day also has heavy squats.
Common injuries / risks?
Shin slips, Achilles irritation, and rushed rebounds. Use a stable box, dry surface, and honest height. Scale when fatigued.
Do I need to open my hips fully on the box?
Most CrossFit standards require standing tall on the box before stepping or jumping down. Check the workout.
Jump down or step down?
Stepping down reduces impact on high-rep pieces. Jumping down is fine for low-rep power work if soft and controlled.
Shoes?
Stable trainers with grip. Avoid slick soles on wooden boxes.
Programming?
Power: low reps, full rest. Conditioning: manageable height, crisp reps, planned step-downs.
Warm-up?
Ankle rocks, easy pogo jumps, low box practice, then working height.
Belt?
Not for box jumps.
Sweat / grip on the box?
Wipe the box; dry shoes. Sweatbands help hands if you are also doing bar work in the same WOD.
