Depth Jump

Body Part: Plyometrics

Muscle: Other

Equipment: Body Weight

Depth Jump is a body-weight plyometric drill that trains reactive power, landing control, and the ability to absorb force before exploding back up. The exercise starts on a low box or bench, where you step off rather than jump down, hit the floor in an athletic landing, and rebound into a vertical jump as quickly and cleanly as you can control.

The setup matters because the box height changes the demand on the ankles, knees, and hips. A lower box gives you a faster, safer contact point and makes it easier to learn the timing of the landing-to-jump transition. A higher box increases impact and usually turns the drill into a sloppy drop instead of a crisp reactive jump.

This movement is useful when your goal is to improve power transfer, sprint carryover, or lower-body explosiveness without adding external load. It also teaches you to keep the trunk stacked while the legs absorb the landing. The supporting muscles listed in this record help stabilize the knees, hips, and trunk, but the real training effect comes from a sharp stretch-shortening cycle, not from fatigue.

Quality reps are fast but not rushed. Step off the box under control, land with the knees tracking over the toes, and use the landing to load immediately into the next jump. If the first landing turns into a deep squat, the rebound gets slow and the exercise stops being a true depth jump.

Use this drill early in a power session, after a warm-up and before heavy strength work, when the nervous system is fresh. Keep the repetitions low, the rest periods generous, and the box height conservative so every rep looks the same. If you cannot land quietly and rebound with the same shape, the set is too hard for the current level.

Instructions

• Place a low box or bench in front of you and stand tall on top with your feet about hip-width apart and your toes near the edge.
• Brace your trunk, keep your chest tall, and prepare to step off rather than jump down from the box.
• Step off the box in control so both feet leave the platform without a push or hop.
• Land on the floor softly with both feet, letting the ankles, knees, and hips bend together into a short athletic squat.
• Keep your knees tracking over your toes and your heels grounded as you absorb the landing.
• As soon as you have a stable landing, drive up forcefully into a vertical jump.
• Swing your arms naturally if they are part of your version, and reach full extension through the hips, knees, and ankles at the top of the jump.
• Land again with the same quiet, balanced mechanics and reset before the next rep.
• Repeat for the planned number of low-volume reps, stopping the set if the landing gets loud or slow.

Tips & Tricks

• Choose a box height that lets you land in the same stance every rep; if you collapse into a deep squat, the box is too high.
• Think of the first contact as an absorb-and-go moment, not a pause, but do not sacrifice knee control for speed.
• The landing should be quiet; noisy feet usually mean you are crashing into the floor instead of storing force.
• Keep your torso slightly forward and your ribs stacked over your pelvis so the jump stays powerful instead of tipped backward.
• Let the knees travel in line with the toes; if they cave inward, lower the box and clean up the landing pattern.
• Use short sets because this drill is about quality and reactivity, not fatigue.
• Rest long enough between reps or sets to keep the jump sharp; plyometrics lose value once you start feeling slow.
• Stop the set if your Achilles, knees, or shins feel overloaded, especially on hard surfaces or with a box that is too tall.

Frequently Asked Questions

What does a depth jump train most?

It trains lower-body explosiveness, landing control, and reactive strength through the stretch-shortening cycle.

Should I jump off the box or step off it?

Step off the box under control. You are preparing for the landing and rebound, not performing a jump down.

How high should the box be for a depth jump?

Use a low box that lets you land in an athletic position without collapsing. If the landing gets deep or sloppy, lower the height.

What is the biggest mistake on the landing?

Letting the knees cave inward or sinking too deeply before jumping again. The landing should be controlled and springy, not a full squat.

How many reps should I do?

Keep the sets short. Depth jumps are usually done for low reps because each rep should stay fast and crisp.

Do I need to use my arms?

You can use an arm swing if that is how you are training the drill, but keep the timing coordinated with the jump rather than flailing for momentum.

Is this exercise good for beginners?

Usually not as a first plyometric. It is better for people who can already land and jump with clean mechanics.

What should I do if the jump feels heavy or slow?

Lower the box, reduce the number of reps, or rest longer. If it still feels slow, the drill is too demanding for that session.
