How high should the box be for a beginner?

Beginners should typically start with a 12 to 18-inch box. The goal is to develop mechanics and land softly rather than testing maximum vertical height.

Is it better to jump or step down?

You should always step down from the box. Jumping backward puts excessive eccentric load on the Achilles tendon and increases the risk of acute injury.

How many reps should I perform for power?

For explosive power, keep repetitions low, generally between 3 to 5 reps per set. Focus on maximum effort and quality of movement rather than cardiovascular fatigue.

Learn how to perform box jumps with proper form. Our coach-led guide covers setup, safety tips, and common mistakes to build lower body explosiveness.

How to Perform

Stand approximately one foot away from the box with your feet positioned shoulder-width apart.
Hinge at your hips and swing your arms back to load your posterior chain and create momentum.
Explode upward by extending your hips, knees, and ankles while swinging your arms forward and up.
Land softly in the center of the box with both feet hitting simultaneously in a partial squat position.
Stand up fully on top of the box to complete the repetition and demonstrate total control.
Step down carefully one foot at a time rather than jumping backward to protect your Achilles tendons and joints.

Common Mistakes

Landing with locked knees which increases joint impact.
Jumping off the box backward instead of stepping down.
Using a box that is too high, leading to a deep crouch landing.
Allowing the knees to cave inward during takeoff or landing.
