Depth Jump
A plyometric exercise where an athlete steps off an elevated platform and immediately jumps vertically, utilizing the stretch-shortening cycle to develop explosive lower-body power.
Instructions
Stand on a plyometric box at a height of 12-24 inches (30-60 cm) with feet hip-width apart. Step off the box with one foot, landing softly on both feet with bent knees. Immediately upon landing, explode upward into a maximal vertical jump, swinging arms for momentum. Land softly and repeat for prescribed repetitions.
Common Mistakes
Landing stiffly with locked knees, which increases joint stress. Stepping off the box instead of stepping directly down. Spending too much time on the ground before jumping (exceeding 200-250ms). Landing with uneven weight distribution. Using excessive box height beyond current capability. Allowing knees to cave inward during landing. Failing to fully extend hips during the jump.
Variations
Depth Jump to Box: Jump onto a second higher box after landing. Single-Leg Depth Jump: Perform the exercise on one leg for increased difficulty. Depth Jump with Med Ball Press: Hold a medicine ball overhead during the jump. Lateral Depth Jump: Jump laterally off the box instead of straight down. Depth Jump to Sprint: Transition immediately into a sprint after landing.
About This Exercise
The depth jump is a fundamental plyometric exercise that develops explosive power through the stretch-shortening cycle (SSC). When you step off the box and land, your muscles undergo an eccentric stretch that stores elastic energy, which is then released during the subsequent jump. This exercise was popularized by Soviet sport scientists and has become a staple in explosive power development programs across many sports. The key to an effective depth jump is minimizing ground contact time while maximizing jump height, which trains the nervous system to recruit muscle fibers more rapidly. Unlike standard vertical jumps, depth jumps create greater force output due to the pre-stretch of the muscles, making them particularly valuable for athletes who need to generate power quickly.
Tips
Land quietly like a cat. Minimize ground contact time. Drive hips through and extend fully at the ankle, knee, and hip. Keep core tight throughout the movement. Use arm swing to complement lower-body power. Maintain neutral spine during flight and landing.
Notes & Safety
Only perform depth jumps after establishing a solid foundation of strength and basic plyometric competency. Ensure proper landing mechanics with soft, bent knees to absorb impact. Start with lower box heights (12-18 inches) before progressing higher. Do not perform on wet or slippery surfaces. Allow adequate recovery between sessions as depth jumps place significant stress on joints. Discontinue if experiencing knee pain during or after the exercise. Not recommended for beginners or individuals with lower-body injuries.
Deep Dive & Exercise Guide
Introduction
The depth jump is one of the most effective plyometric exercises for developing explosive lower-body power. This exercise involves stepping off an elevated platform and immediately transitioning into a maximal vertical jump, capitalizing on the stretch-shortening cycle to generate greater force output than a standard jump. Used extensively by athletes across sports, the depth jump is a cornerstone movement in any explosive power development program.
Benefits & Muscles Involved
Depth jumps offer numerous performance benefits, including improved reactive strength, increased vertical leap, enhanced rate of force development, and better neuromuscular efficiency. The primary muscles engaged during depth jumps include the quadriceps and glutes, which provide the majority of the explosive power during the upward phase. Secondary muscles include the hamstrings, calves, hip flexors, and core musculature, which work together to stabilize the body during flight and landing phases. The stretch-shortening cycle activates the elastic components of muscles and tendons, allowing for greater power production than isolated strength exercises alone.
How It Fits Into Training
Depth jumps should be placed early in your training session when you are fresh and your nervous system is fully activated. They pair well with heavy strength work and are commonly programmed after the main strength lifts or as part of a dedicated plyometric circuit. Typically, depth jumps are performed for 3-5 sets of 3-6 repetitions with adequate rest between sets (2-3 minutes). This exercise is particularly beneficial for athletes in sports requiring explosive jumping, sprinting, or rapid direction changes, including basketball, volleyball, track and field, football, and soccer.
Who Should Use It
Depth jumps are best suited for intermediate to advanced athletes who have already developed a solid foundation of strength. Beginners should first master basic plyometric movements and build adequate lower-body strength before attempting depth jumps. Athletes looking to improve vertical jump height, sprint acceleration, or reactive strength will benefit significantly from incorporating depth jumps into their training. However, individuals with knee, ankle, or lower-back injuries should approach this exercise with caution or avoid it entirely until fully recovered.
Programming Considerations
When programming depth jumps, start with lower box heights (12-18 inches) and focus on quality over quantity. Progress by increasing box height gradually or by adding variations such as depth jumps to box or lateral depth jumps. Always ensure proper recovery between sessions, as plyometric exercises place significant stress on joints and connective tissues. Two to three depth jump sessions per week with at least 48 hours between sessions is appropriate for most athletes. Monitor for signs of excessive fatigue, such as declining jump height or deteriorating landing mechanics.
Tips for Better Performance
To maximize the effectiveness of depth jumps, focus on minimizing ground contact time. Your goal should be to leave the ground within 200-250 milliseconds of landing. Step off the box with control but avoid hesitating at the edge. Land with bent knees and soft feet, distributing weight evenly across both legs. Drive your arms upward as you jump to complement lower-body power. Keep your core engaged throughout the movement to maintain stability. Practice landing mechanics regularly, as perfect technique will prevent injury and improve performance.
FAQs
How high should the box be for depth jumps?
For most athletes, box heights between 12-24 inches are appropriate. Beginners should start at 12 inches and progress gradually. Higher boxes create greater impact forces but also increase injury risk if technique is poor.
How many depth jumps should I do?
Perform 3-5 sets of 3-6 repetitions with 2-3 minutes rest between sets. Total weekly volume should not exceed 50-100 foot contacts to avoid overtraining.
Can beginners do depth jumps?
Depth jumps are not recommended for complete beginners. You should first establish a strength base and master basic jumping mechanics before adding this advanced plyometric exercise.

Conclusion
The depth jump is a powerful exercise for developing explosive lower-body power through the stretch-shortening cycle. When performed with proper technique and appropriate progression, it can significantly enhance athletic performance, particularly for athletes requiring rapid force production. Always prioritize quality over quantity, respect your current fitness level, and allow adequate recovery to maximize benefits while minimizing injury risk.
