Most athletic training programmes are dominated by bilateral exercises: two-leg squats, two-leg box jumps, two-leg depth jumps. These exercises are valuable and form an important foundation, but they share a significant limitation for most sports: almost no athletic action of consequence is bilateral.
Running uses one leg at a time. Jumping for a basketball rebound uses one leg at a time. Changing direction in football uses one leg at a time. Kicking a ball uses one leg at a time. The only common athletic actions that are truly bilateral are swimming starts and powerlifting. For every other sport, the primary explosive actions are unilateral, and bilateral plyometric training only partially prepares athletes for these demands.
Single-leg plyometrics specifically develop the explosive power, reactive strength, and stability of one leg at a time, in the patterns that athletic performance actually requires. This guide covers the complete single-leg plyometric exercise toolkit, the prerequisites for using it safely, and a structured programme that develops the unilateral explosive power that bilateral training alone cannot provide.
Why Single-Leg Plyometrics Are Different
The difference between bilateral and single-leg plyometrics is not simply a matter of difficulty. They develop qualitatively different physical qualities.
Bilateral strength deficit: Research has consistently found that the sum of the forces two legs produce individually in single-leg tests exceeds the force they produce together in a bilateral test. This bilateral strength deficit means that two-leg exercises are performed at a fraction of the capacity available to each leg individually. Single-leg exercises force each leg to operate at its actual capacity rather than at the reduced output of the bilateral pattern.
Stability and balance demands: Single-leg plyometrics require the hip abductors, external rotators, and ankle stabilisers to work actively to maintain balance during the brief contact phase. These stability demands are absent from bilateral exercises. In athletic contexts where stability failures produce injury (ankle sprains, ACL tears), the stability training of single-leg plyometrics provides specific protection.
Asymmetry identification: Single-leg plyometric testing reveals strength and power asymmetries between legs that bilateral testing conceals. Research has found that leg-to-leg asymmetries of more than 10 to 15 percent in reactive strength are associated with increased injury risk and reduced performance. Bilateral testing cannot identify these asymmetries.
Sprint and running specificity: Every running stride involves a single-leg contact of 80 to 300 milliseconds. The reactive strength that determines running performance is the single-leg reactive strength of each stride contact. No bilateral exercise replicates this demand.
Prerequisites for Single-Leg Plyometric Training
Single-leg plyometrics are more demanding than their bilateral equivalents and require adequate strength and control foundations before being introduced.
Strength prerequisites:
- Ability to perform 5 single-leg squats (pistol squat progression) per leg with full depth and controlled descent
- Single-leg calf raise: 15 consecutive reps per leg on a flat surface
- Single-leg Romanian deadlift: ability to perform 8 reps per leg with bodyweight or light load with controlled balance
Balance and stability prerequisites:
- Single-leg balance: 30 seconds per leg with eyes open and minimal wobble
- Single-leg balance with eyes closed: 15 seconds per leg
- Single-leg hop and stick: ability to hop forward from one leg and land on the same leg, holding the landing position for 3 seconds without falling
Bilateral plyometric prerequisites:
- Bilateral box jump competency: 3 sets of 5 at 50cm with quiet, controlled landings
- Bilateral depth jump competency: 3 sets of 5 at 40cm with minimal knee bend
- RSI above 1.0 on bilateral depth jump testing
Athletes who cannot meet these prerequisites should develop the bilateral plyometric and strength foundations before introducing single-leg plyometric work.
Assessing Single-Leg Asymmetry
Before beginning a single-leg plyometric programme, assessing the strength and power asymmetry between legs identifies which leg needs additional attention.
Single-leg box jump assessment:
Perform 3 single-leg box jumps per leg onto a 40cm box. Observe:
- Which leg can jump onto a higher box?
- Which leg shows more knee valgus (inward collapse) during the jump?
- Which leg produces a louder, less controlled landing?
The weaker leg should receive additional volume in the single-leg plyometric programme.
Single-leg hop for distance assessment:
Stand on one leg and hop forward as far as possible, landing on the same leg. Measure the distance from the toe of the standing foot to the heel of the landing foot. Compare both legs. A difference of more than 10 percent between legs warrants targeted single-leg work on the shorter-hopping leg.
Single-leg drop and stick:
Step off a 30cm box onto one leg and hold the landing position for 3 seconds. Observe:
- Does the knee collapse inward?
- Does the trunk lean excessively to one side?
- Does the ankle roll?
These observations identify the specific stability deficits that single-leg plyometric training needs to address.
Single-Leg Plyometric Exercises
Foundation Exercises
Single-Leg Pogo Jump
Athletic quality developed: Unilateral Achilles tendon reactive strength and ankle stiffness, the primary determinants of single-leg ground contact time in running.
How to do it:
- Balance on one foot on the ball of the foot
- Perform continuous rapid jumps using only ankle extension
- The knee remains relatively straight throughout
- Maintain a consistent, rapid rhythm
- Complete 3 sets of 15 reps per leg with the same rhythm quality on both sides
Key cue: Compare the sound and height of each leg. A noticeably louder or lower bounce on one side indicates an Achilles reactive strength deficit on that side. Give the weaker side an additional set until symmetry approaches.
Single-Leg Ankle Hop
Athletic quality developed: Basic single-leg reactive coordination and ankle stability at low intensity. The entry-level single-leg plyometric.
How to do it:
- Stand on one foot
- Perform small, rapid hops using only ankle extension
- Keep the height minimal and focus on consistency of rhythm
- Complete 3 sets of 20 reps per leg
Hop and Stick
Athletic quality developed: Single-leg landing mechanics and deceleration control. Essential before progressing to any reactive single-leg exercises.
How to do it:
- Stand on one leg
- Hop forward, sideways, or backward a short distance (30 to 50 centimetres)
- Land on the same leg and hold the landing position completely still for 3 seconds
- The knee should track over the second toe on landing
- No wobble, no additional hop to regain balance
- Complete 3 sets of 6 hops in each direction per leg
Key cue: The landing quality is everything in this exercise. A wobbly or collapsed landing means the stability foundations are not adequate for more reactive single-leg work. Master this before progressing.
Single-Leg Box Jump
Athletic quality developed: Unilateral concentric jump power and landing control.
How to do it:
- Stand on one leg facing a box of 30 to 40cm
- Lower slightly and jump onto the box from one leg
- Land on both feet on the box
- Step down and repeat
- Complete 3 sets of 5 reps per leg
Progression: Increase the box height as single-leg jump power develops. Advanced athletes can land on one leg rather than two on the box.
Intermediate Exercises
Single-Leg Broad Jump (Hop for Distance)
Athletic quality developed: Horizontal single-leg explosive power directly relevant to sprint acceleration mechanics.
How to do it:
- Stand on one leg
- Load into a quarter squat position on the standing leg
- Drive forward explosively, covering maximum horizontal distance
- Land on both feet
- Measure the distance and compare legs
- Complete 3 sets of 5 reps per leg
Progression: Land on the jumping leg rather than both feet. This single-leg to single-leg hop (standing long jump on one leg) is significantly more demanding and develops both the push-off and landing mechanics of unilateral bounding.
Lateral Single-Leg Bound
Athletic quality developed: Lateral explosive power from a single-leg push-off, directly relevant to direction changes, defensive footwork, and cutting movements.
How to do it:
- Stand on one leg
- Push off powerfully to the side, covering maximum horizontal distance
- Land on the opposite leg
- Stabilise the landing and push off again
- Continue alternating for the prescribed repetitions
- Complete 3 sets of 6 bounds per side
Key cue: The landing must be fully controlled before the next push-off. Athletes who immediately push off from an unstable landing are developing poor movement habits that increase injury risk during sport-specific direction changes.
Single-Leg Depth Jump
Athletic quality developed: Unilateral fast SSC performance at the highest reactive strength demand. The most powerful single-leg plyometric exercise.
How to do it:
- Step off a box of 30 to 40cm onto one leg
- Contact the ground with minimal knee bend on the landing leg
- Immediately jump upward from the single leg contact
- Drive the free knee and opposite arm upward during the jump
- Complete 3 sets of 4 reps per leg with full recovery
Prerequisites: Solid bilateral depth jump technique and competency, hop and stick mastery, RSI above 1.0.
Key cue: The single-leg depth jump exposes reactive strength deficits between legs clearly. The weaker leg typically shows a longer contact time, deeper knee bend, and lower jump height. Track the difference and give the weaker leg additional volume until asymmetry reduces below 10 to 15 percent.
Continuous Single-Leg Hop
Athletic quality developed: Single-leg reactive endurance, the ability to sustain reactive force production through repeated contacts on the same leg.
How to do it:
- Stand on one leg
- Perform 5 continuous forward hops on the same leg
- Cover maximum distance with each hop
- Land and immediately take the next hop with minimal contact time
- Complete 3 sets of 5 hops per leg
Progression: Increase the number of hops per set (5 to 8 to 10). Further progress to hopping over low hurdles (20 to 30cm) to add a consistent height demand.
Single-Leg Hurdle Hop
Athletic quality developed: Reactive single-leg power over a consistent obstacle, developing the approach-to-hurdle mechanics relevant to sprint hurdles and jump events.
How to do it:
- Set up 3 to 5 hurdles of 20 to 40cm in a line, spaced 1 to 1.5 metres apart
- Hop over each hurdle on one leg consecutively
- Focus on minimal contact time and consistent rhythm
- Complete 3 passes per leg
Key cue: The rhythm between hurdles should be consistent. Inconsistent rhythm between contacts indicates reactive strength endurance is limiting. Begin with fewer hurdles and build to more as endurance develops.
Advanced Exercises
Single-Leg Depth Jump to Sprint
Athletic quality developed: The transition from unilateral reactive landing to explosive sprint acceleration. The most sport-specific single-leg plyometric exercise.
How to do it:
- Step off a box of 35 to 45cm onto the takeoff leg
- Contact the ground and immediately accelerate into a maximal 20 to 30m sprint
- The sprint should begin within one stride of the single-leg landing contact
- Complete 4 to 6 reps with full recovery
Sport applications: Any field or court sport where an explosive first step follows a reactive landing or direction change.
Reactive Single-Leg Hop With Direction Change
Athletic quality developed: Reactive single-leg power with an added cognitive and reactive agility component, the most sport-specific agility-plyometric combination available.
How to do it:
- Stand on one leg
- A partner calls a direction (forward, backward, left, right) at the moment of the hop
- Immediately redirect the hop in the called direction
- Land and hold or continue as directed
- Complete 4 sets of 6 calls per leg
Triple Hop for Distance (Single-Leg)
Athletic quality developed: Single-leg reactive endurance across multiple contacts, used as both a training exercise and an athletic performance assessment.
How to do it:
- Stand on one leg
- Perform 3 consecutive maximum-distance hops on the same leg
- Measure the total distance covered by the 3 hops
- Compare both legs
- Complete 3 sets per leg
Athletic benchmarks for the triple hop:
- Recreational athletes: 3.5 to 4.5 metres per leg
- Trained athletes: 4.5 to 6.0 metres per leg
- Elite athletes: 6.0 to 7.5 metres per leg
A difference of more than 10 percent between legs indicates a meaningful asymmetry.
Bounding (Alternating Single-Leg)
Athletic quality developed: Alternating single-leg explosive power in the horizontal direction, the most specific exercise for sprint and running performance.
How to do it:
- Push off from one leg and land on the opposite leg
- Immediately push off from the landing leg
- Cover maximum distance per bound
- Drive the opposite arm and free knee upward with each bound
- Complete 3 to 4 sets of 40 to 60 metres
Why bounding is the most running-specific single-leg plyometric: Every running stride involves a single-leg push-off followed by a single-leg landing on the other side. Bounding replicates this pattern with maximum effort, developing the specific reactive qualities of running at distances that meaningful ground contact time training occurs.
How Single-Leg Plyometrics Connect to Running Performance
The connection between single-leg plyometric training and running performance is the most direct of any training intervention:
Ground contact time: Running ground contact time (80 to 300 milliseconds depending on pace) is a single-leg reactive event. Every improvement in single-leg reactive strength from single-leg pogo jumps and single-leg depth jumps directly reduces ground contact time at a given running pace, improving running economy.
Stride length: Single-leg broad jump performance is significantly correlated with running stride length. Athletes who develop greater single-leg horizontal explosive power through bounding and single-leg broad jumps naturally develop longer, more powerful running strides.
Running asymmetry: Just as bilateral testing misses bilateral strength deficits, bilateral running analysis misses the leg-to-leg asymmetries that affect running efficiency. Single-leg plyometric training reduces these asymmetries by specifically targeting the weaker leg.
Injury resilience: Single-leg plyometric training develops the hip abductor and external rotator stability that protects the knee during single-leg landing. Research has consistently found that athletes with better single-leg landing mechanics have significantly lower ACL injury rates.

Sport-Specific Single-Leg Plyometric Applications
Sprinters and track athletes:
Emphasise bounding, single-leg pogo jumps, and single-leg depth jump to sprint. The horizontal reactive power of bounding is the most specific exercise for sprint performance.
Basketball and volleyball:
Emphasise single-leg box jump (increasing height), single-leg depth jump for vertical reactive strength, and single-leg hurdle hops. Both sports require explosive single-leg vertical jumping ability.
Football (soccer):
Emphasise lateral single-leg bounds, single-leg depth jump to sprint for explosive first step, and reactive single-leg hops with direction changes.
Distance runners:
Emphasise single-leg pogo jumps, forward single-leg pogo jumps, and light bounding. Keep intensity moderate and integrate with running programme carefully to avoid excessive total loading.
High jumpers:
Emphasise single-leg depth jump with arm and knee drive matching takeoff mechanics, single-leg hurdle hops, and bounding. See the high jump plyometrics article on this site for the complete high jump-specific programme.
Frequently Asked Questions
Should I do more single-leg or bilateral plyometrics?
Both have a place in a complete programme. Bilateral plyometrics build the general explosive power foundation and are appropriate for beginners. Single-leg plyometrics develop the sport-specific unilateral qualities that bilateral training cannot provide. An effective programme for most athletes includes approximately 60 percent single-leg work and 40 percent bilateral work once the bilateral foundations are established.
Is it normal for one leg to be significantly stronger than the other?
Mild asymmetry of 5 to 8 percent is common and not concerning. Asymmetry of more than 10 to 15 percent in reactive strength tests is associated with injury risk and warrants targeted unilateral work to reduce the difference. Asymmetries of more than 20 percent should be assessed by a sports physiotherapist to identify whether an underlying injury or structural issue is contributing.
Can single-leg plyometrics cause knee injuries?
Single-leg plyometrics performed with poor mechanics, specifically knee valgus (inward collapse) during landing, are associated with increased ACL and patellar tendon stress. However, single-leg plyometric training with appropriate progression and good landing mechanics is one of the most evidence-supported interventions for reducing ACL injury risk by developing the hip abductor and external rotator strength that prevents knee valgus during athletic landing.
How do I know when I am ready to progress to single-leg depth jumps?
The criteria are: solid bilateral depth jump technique at 40cm, hop and stick mastery (landing from a 30cm box on one leg without wobble), single-leg box jump ability at 40cm, and RSI above 1.0 bilaterally. Athletes who meet all of these criteria are ready to begin single-leg depth jumps from a conservative box height of 25 to 30cm.
Do single-leg plyometrics help with running injuries?
Yes, in several ways. They develop the hip abductor strength that reduces knee valgus during running, which is associated with IT band syndrome, patellofemoral pain, and ACL injury risk. They develop the single-leg landing mechanics that reduce ankle sprain risk. And they develop the Achilles tendon stiffness through single-leg pogo jumps that reduces the risk of Achilles tendinopathy during mileage increases.
