Do Squats Increase Vertical Jump? + Hip Thrusts & Plyometrics

The Science: Squat Strength and Jump Height

Multiple studies show that maximal squat strength correlates strongly with vertical jump performance, especially in athletes who have not trained specifically for jumping. The reason is mechanical: a jump is a ~0.2-0.3 second maximum push against the ground, and your takeoff velocity depends on the force you apply in that window. A stronger athlete has more force available, so the ceiling is higher.

Markovic and Jaric (2007) showed that jump performance is essentially high-velocity mechanical output of the leg extensors. Heavy squats train that system to produce high force; the missing step is learning to produce it fast. That is why the best research-supported approach pairs a progressive squat program with ballistic and plyometric training.

Peterson, Rhea and Alvar (2004) meta-analyzed strength training dose-response and found that untrained and recreationally trained individuals make the fastest strength gains with 3-4 sets per muscle group, 2-3 days per week. Wernbom, Augustsson and Thomeé (2007) confirmed that meaningful muscle growth requires progressive loading over months. In short: get strong with squats, then learn to jump.

The correlation numbers are worth knowing. Studies of recreationally trained men routinely report correlations between 1RM back squat and countermovement jump height in the range of 0.70 to 0.85. In elite weightlifters, who are squatting several times their body weight, the correlation drops, because at that point everyone is strong and technique and speed separate the jumpers. Your place on that curve tells you what to train next.

That training decision is the practical payoff of this whole discussion. Test your squat and your jump together. If your jump percentile sits far below your squat percentile, you have a power deficit and need plyometrics and jump squats. If both are low, you have a strength deficit and the squat should be your priority. If your jump is already strong relative to your squat, keep strength work in maintenance mode and spend your training budget on speed and elasticity. Most jump programs fail because they run every athlete through the same drill, when the deficit that needs fixing varies from person to person.

Squat Depth: Full vs. Partial for Jumping

Squat depth is a frequent debate in jump training. Here is what the evidence and practical experience suggest:

If you can only do one squat, do a full back squat. Partial squats place heavy loads on the exact joint angles of a jump, but they do not build the deep-leg strength and mobility that full squats provide. Most athletes benefit from full squats as the main lift and partial or jump squats as accessories.

There is a subtlety worth understanding. The knee angle at the bottom of a countermovement jump is typically 60 to 90 degrees of flexion, shallower than a full squat. So some coaches argue for quarter squats because they are angle-specific. The counterargument, supported by the hypertrophy literature (Wernbom et al., 2007), is that a full range of motion builds more total muscle and force capacity, and that capacity transfers across angles. Full squats win for long-term development; partial squats are a fine specialization tool once full depth is strong.

Do Hip Thrusts Help Vertical Jumps?

Hip thrusts are popular for glute development, and strong glutes contribute to hip extension power, a driver of jump takeoff. However, the evidence that hip thrusts directly improve vertical jump is thinner than for squats and plyometrics. Hip thrusts are an excellent accessory for glute strength, injury prevention, and balance, but they should support a program built around squats, hinge lifts, and jumps.

• Include them: 3-4 sets of hip thrusts once or twice per week strengthen the glutes and help keep hip extension dominant over back extension during jumps.
• Do not replace the main work: hip thrusts are an accessory. Squat, hinge, and jump training remain the core of any vertical jump program.
• Expect modest direct gains: if your glutes are weak, hip thrusts will help your jump. If they are already strong, they add little height compared to plyometrics.

Think of hip thrusts as insurance. Glute weakness shows up as a forward-bent torso at takeoff and a lower jump than your quad strength suggests. Thrusts fix that pattern. But a 200 kg hip thrust will never substitute for a 150 kg squat, because the squat trains the exact extension pattern of the jump under load, while the thrust trains it lying down.

Plyometrics: The Missing Link

Strength is the ceiling; plyometrics teach you to hit it. Meta-analytic research (Markovic, 2007; de Villarreal et al., 2009) consistently shows that plyometric training improves vertical jump by 5-10%, and that combining plyometrics with resistance training produces larger gains than either method alone. Depth jumps, box jumps, and max-effort countermovement jumps train the fast stretch-shortening cycle that a jump uses.

• Depth jumps: step off a 12-30-inch box and jump immediately on landing: the most powerful plyometric, use sparingly.
• Box jumps: build takeoff speed and landing skill with lower injury risk.
• Jump squats at 20-30% of 1RM: bridge heavy strength and plyometric power.
• Pogo hops: ankle stiffness and rapid rebound for the final push of takeoff.

The volume guidance from the meta-analyses is surprisingly low: 10-20 maximal jumps per session, 2-3 times per week. This is where squat strength and plyometric speed meet. A stronger athlete can absorb a depth jump drop with better control and rebound faster, which is exactly why the two training modes work together instead of competing. For the complete schedule see the 8-week vertical jump training program.

The Transfer Problem: Why Strong People Sometimes Cannot Jump

If squats correlate so well with jumping, why do so many powerlifters jump poorly? The answer is that correlation describes groups, not individuals, and it holds up to a point. A powerlifter squatting 2.5x body weight has enormous force available, but if that force is expressed over 1.5 seconds instead of 0.25 seconds, it produces a mediocre jump. Rate of force development is a separate trainable quality.

There is also the body weight problem. A heavier lifter has to launch more mass, and absolute squat strength scales with body mass. Two athletes with the same squat-to-bodyweight ratio jump similarly, all else equal, which is why your strength-to-weight ratio is the number to track, not your raw 1RM. If you gain 5 kg of muscle while your squat climbs 5 kg, your jump does not change; if you lose 5 kg of fat and keep the squat, it does.

The timing of force matters just as much as its magnitude. Picture two lifters who both deadlift 200 kg. One reaches peak force in 0.15 seconds, the other in 0.6 seconds. In a jump, the ground contact lasts roughly 0.25 seconds, so the first athlete expresses useful force, while the second is still building it as the feet leave the floor. That is the rate of force development gap, and it explains why the correlation between squat and jump is strong but never perfect. The good news is that rate of force development is trainable: ballistic exercises like jump squats, depth jumps, and kettlebell swings push force production to the fast end of the spectrum, while heavy squats keep pushing the ceiling up.

Putting It Together: A Balanced Approach

1. Train squats 2x per week with progressive overload until you approach a 1.5-2x bodyweight squat.
2. Add 1-2 power sessions per week with jump squats and plyometrics once basic strength exists.
3. Use hip thrusts as accessories for glute strength and balance, not as your primary jump exercise.
4. Monitor strength relative to body weight: your strength-to-weight ratio predicts jump height better than raw squat numbers.
5. Retest every 4 weeks with the vertical jump calculator to confirm the training is working.
6. Rotate phases: several weeks emphasizing the squat, then several emphasizing plyometrics, and let the two inform each other.

This mirrors how real strength and conditioning programs are written. The strength block raises the ceiling, the power block teaches the ceiling to be reached fast, and the peaking block puts the two together on test day.

Mistakes to Avoid in the Squat-to-Jump Program

• Only squatting, never jumping: strength without power training leaves most of your potential unexpressed. Add jumps to your program.
• Only jumping, never squatting: the opposite failure: without a strength base, plyometrics plateau and injury risk rises.
• Expecting hip thrusts to add inches: they help weak glutes but are not a jump-specific tool. Spend the same time on depth jumps.
• Chasing a heavy squat with sloppy depth: a 2x bodyweight half-squat will not build the leg strength a full squat does. Full range matters.
• Ignoring body weight: adding muscle mass without losing fat reduces your jump. Your strength-to-weight ratio is the metric to watch.
• Jumping in the same session as heavy legs: doing max jumps after heavy squats measures fatigue, not power. Separate them by a day.

Squat Training for Jumping: Age and Sport Context

The squat-to-jump transfer is relevant at every level of sport. Adolescent athletes benefit from properly coached squatting and plyometrics: Harries, Lubans and Callister (2012) systematically reviewed resistance training in adolescents and found significant power and sport performance improvements with well-supervised programs, contradicting the old myth that children should not lift. For younger athletes, technique and light-to-moderate loads matter more than heavy 1RMs.

In older adults, the squat-to-jump relationship flips in an interesting way. Absolute jump height matters less than maintaining rate of force development, because that quality protects against falls and supports daily activities like stair climbing and catching yourself on uneven ground. Squatting with controlled speed, jumping lightly, and doing step-ups preserves power in a population where losing it has real consequences. The same gait speed and grip strength declines that track age also respond to the same strength training.

For sport-specific standards, know where you are aiming. Basketball and volleyball players want a vertical jump of 24-28 inches or more; the NFL Combine average is about 30 inches. The horizontal standing long jump is tested alongside it because it captures the same power. Whatever the target, the path runs through the squat, the hinge, and the plyometric box, in that order.
