An advanced plyometric exercise that develops reactive strength and explosive power through rapid deceleration and maximal vertical rebound.

Depth Jump

Instructions

  • Stand upright on a sturdy plyometric box with feet hip-width apart and toes near the front edge.
  • Step off the box with one foot, dropping straight down toward the floor without jumping upward or outwards.
  • Land softly on the balls of both feet simultaneously with knees slightly bent to absorb impact.
  • Immediately reverse the downward momentum by exploding vertically into a maximum-effort jump.
  • Reach upward with both arms during takeoff and land softly in a balanced, athletic position on the ground.

    Common Mistakes

    • Jumping up off the box instead of stepping down, which increases drop height and alters timing.
    • Excessive ground contact time caused by sinking too deep into a squat upon landing.
    • Knee valgus (knees caving inward) during impact and takeoff.
    • Using a box that is too high, leading to protective inhibition rather than reactive power.
    • Performing repetitions under fatigue, which degrades neural recruitment and increases injury risk.

      • Variations

      • Depth Jump to Box Jump: Rebounding directly onto a second elevated box.
      • Depth Jump to Broad Jump: Redirecting vertical drop force into maximal horizontal distance.
      • Single-Leg Depth Jump: An elite progression emphasizing unilateral deceleration and reactive force.
      • Drop Jump: Landing with minimal knee flexion to prioritize ankle stiffness and ultra-short ground contact times.

        • About This Exercise

        Originally popularized as the ‘shock method’ by Soviet sport scientist Yuri Verkhoshansky, the depth jump is considered the pinnacle of reactive plyometric training. By dropping from an elevated platform, the athlete experiences rapid eccentric loading upon contact with the ground. This stimulates the stretch reflex (myotatic reflex) and stores elastic strain energy in the tendon structures, which is immediately unleashed during the subsequent vertical jump. It specifically targets the fast stretch-shortening cycle (SSC < 250 milliseconds), significantly improving rate of force development and reactive strength index (RSI).

        Tips

        • Step, do not jump, off the box.
        • Minimize ground contact time—treat the floor like hot coals.
        • Land with stiff ankles and reactive knees.
        • Drive the arms forcefully upward as you rebound.
        • Absorb the final landing with control in a quarter-squat position.

          • Notes & Safety

          Depth jumps place intense mechanical stress on the lower extremity joints, patellar tendons, and Achilles tendons. Athletes should possess a solid base of general strength (traditionally able to back squat 1.5 to 2.0 times bodyweight) before incorporating depth jumps. Discontinue immediately if acute joint or tendon discomfort arises.

          Introduction

          The depth jump is one of the most powerful and demanding exercises in athletic performance training. Pioneered by Professor Yuri Verkhoshansky as part of the shock method, this exercise trains the neuromuscular system to absorb high impact forces and instantly convert them into maximal explosive output. For athletes seeking to increase vertical jump height, sprinting speed, and change-of-direction speed, mastering the depth jump is an essential milestone.

          Benefits & Muscles Involved

          The depth jump targets the entire lower-body kinetic chain. The primary drivers of the movement are the quadriceps and the calves (specifically the gastrocnemius and soleus complex working with the Achilles tendon). The glutes and hamstrings act as secondary contributors, providing hip extension and stabilizing the pelvis during high-force contact.

          Key benefits include:

          • Enhanced reactive strength index (RSI) and tendon stiffness.
          • Optimized stretch-shortening cycle (SSC) efficiency.
          • Superior rate of force development (RFD).
          • Improved neuromuscular coordination under high-velocity eccentric loads.

          How It Fits Into Training

          Because the depth jump requires maximal central nervous system (CNS) recruitment, it should be placed early in a workout immediately following a thorough dynamic warm-up. It fits naturally into power and speed training blocks, paired with sprint work or preceding heavy, low-volume strength training within complex training protocols.

          Who Should Use It

          This exercise is designed for advanced and elite athletes involved in power-dependent sports such as track and field (sprinting, jumping), basketball, volleyball, football, and rugby. Beginners and intermediate athletes should develop basic landing mechanics and lower-body strength through drop landings and countermovement jumps before progressing to depth jumps.

          Programming Considerations

          Volume for depth jumps should be strictly limited to ensure quality over quantity. Prescribe 2 to 4 sets of 3 to 6 repetitions per session, with 2 to 3 minutes of passive rest between sets to allow full neural recovery. Total weekly contacts should generally range between 20 and 40 jumps for most competitive athletes. Box height typically begins around 30 to 45 cm, only advancing if ground contact time does not increase.

          Tips for Better Performance

          To maximize benefits, prioritize short ground contact times rather than deep squatting. Focus on stepping off the box rather than jumping down, and imagine bouncing off the floor as if it were a rigid spring. Use your arms aggressively to assist in vertical displacement, and maintain an upright, braced torso throughout the ground strike.

          FAQs

          What is the difference between a drop jump and a depth jump?
          While often used interchangeably, a drop jump typically emphasizes minimal knee flexion and the shortest possible contact time, relying primarily on ankle stiffness. A depth jump allows slightly more knee and hip flexion to generate maximum jump height.

          How high should the box be?
          Optimal box height varies by individual strength and reactive ability, usually falling between 30 cm and 75 cm. If increasing height causes longer ground contact times or lower jump heights, the box is too high.

          Conclusion

          The depth jump stands as the gold standard for developing reactive power and tendon efficiency. When applied with strict technique, adequate recovery, and appropriate volume, it delivers unmatched improvements in athletic explosiveness.
