How to Increase Your Vertical Leap (Add 4+ Inches)

To increase your vertical leap, you have to train three things at once: lower-body strength, explosive plyometric power, and clean jump technique. Strength decides how much force your legs can produce, plyometrics teach you to produce it fast, and technique keeps that force from leaking out through a lazy arm swing or a sloppy dip. Test where you stand now, then follow the plan below and most people add 2 to 6 inches in 8 to 12 weeks.

The single fastest win is technique, because it needs no new strength. The biggest long-term gains come from getting stronger and more explosive. This is the action-focused companion to our complete vertical jump training guide, narrowed down to the exact steps that add inches.

How many inches can you add to your vertical leap?

Realistically, expect 2 to 6 inches over a focused 8-to-12-week block, and 6 to 10 inches across a full year if you start relatively weak. The gains are not evenly distributed. Untrained beginners and lighter athletes see the largest early jumps because they have the most slack to remove, while athletes who already squat well and jump often are closer to their ceiling and gain slower.

Two levers set your personal number: how much strength you have relative to your body weight, and how efficiently you convert that strength into a fast push. If you are strong but jump poorly, your gains will come from power and technique. If you are weak, strength work moves the needle most.

Step 1: Test your vertical leap first

Measure before you train, or you will never know if anything worked. The simplest method is a reach-and-jump test: stand side-on to a wall, mark your standing reach with a flat hand, then jump and mark the highest point you touch. The distance between the two marks is your vertical. A jump mat, a Vertec, or slow-motion phone video all work too, and our guide on how to measure your vertical jump walks through each method and its accuracy.

Record the number, the date, and the conditions. Then retest every four weeks at the same time of day, after the same warm-up, taking the best of three attempts. Testing more often just adds noise, because fatigue and time of day can swing a single result by an inch or more.

Step 2: Build lower-body strength (the ceiling)

Strength is the foundation, and you cannot out-jump a weak posterior chain. Aim for two to three lower-body sessions a week built around heavy, controlled compound lifts. These four cover the muscles that drive a jump:

1. Back or front squat — 3 to 4 sets of 4 to 6 reps. The best general strength builder for jumping.
2. Romanian or trap-bar deadlift — 3 sets of 5 to 8 reps, training the hamstrings and glutes through full hip extension.
3. Hip thrust — 3 sets of 6 to 10 reps, hitting the glutes directly, the primary engine of jump height.
4. Single-leg work (split squats, step-ups) — 2 to 3 sets of 6 to 8 reps per leg, since most game jumps are off one foot.

Beginners should own the bodyweight and light-load versions before adding real weight. A rough target worth chasing is a back squat around 1.5 times your body weight, which is also the point at which the most demanding plyometrics become safe. The full progression lives in our vertical jump strength training plan.

Step 3: Train plyometrics to turn strength into power

Strength is potential; plyometrics are how you cash it in. This training teaches your nervous system to fire quickly and to use the stretch-shortening cycle, the rapid stretch-then-contract action that makes a jump snappy instead of slow. Train these twice a week, never on back-to-back days, and do them before your strength work while your legs are fresh:

1. Squat jumps — pause at the bottom of a squat, then jump as high as you can with no dip. 3 to 4 sets of 4 to 6 reps.
2. Countermovement jumps — a normal max-effort vertical with a quick dip and full arm swing. 3 to 4 sets of 4 to 5 reps.
3. Tuck jumps — jump and pull both knees toward your chest, landing soft. 3 sets of 5 reps, useful before you have access to a box.
4. Depth jumps — step off a 12-to-18-inch box, land, and instantly explode upward. The most demanding drill; add it only once you squat around 1.5x body weight. 3 sets of 4 to 5 reps.

Rest 60 to 90 seconds between sets and treat every rep as near-maximal, not a tired grind. Box work deserves its own session structure, covered in our box jump workout, and the full drill menu is in plyometric exercises for vertical jump. No gym or box? You can build real power with vertical jump exercises at home using only body weight and a sturdy step.

Step 4: Fix the technique that leaks height

Technique is free inches most people leave on the floor. None of it requires getting stronger, which is why it pays off within a week or two:

1. Full arm swing. Drive both arms down and back as you dip, then throw them forcefully overhead as you leave the ground. Worth 2 to 4 inches on its own.
2. Quick, moderate dip. Sink to about a quarter-to-half squat and reverse instantly. Too shallow wastes stored energy; too deep stalls the transition. It should feel like a bounce, not a pause.
3. Push through the whole foot. Drive through mid-foot and heel first, then finish up on the balls of your feet, rather than jumping off flat feet or only the toes.
4. Attack the takeoff. Approach jumps gain height from a penultimate step that plants hard and converts run-up speed into lift.

Film yourself from the side. Flaws like an early arm drop or a slow, deep dip are obvious on video but nearly impossible to feel in real time.

The fastest way to add inches in two weeks

If you need a quick jump before a tryout or a pickup game, skip the long build and drill technique. For ten to fifteen minutes, three or four times across two weeks, rehearse the arm swing in isolation, then practice quick-dip countermovement jumps at full effort with long rest between reps. Add a few sets of low box jumps focused on a soft landing.

This will not build new muscle, but it removes the mechanical waste in your current jump, and that alone commonly returns 2 to 3 inches. Just do not confuse it with the real program. Lasting gains still come from getting stronger and more explosive over months.

Common mistakes that stall your vertical

• Plyometrics with no strength base. Power gains plateau fast without strength underneath. Fix: train both, strength first each week.
• Jumping every day. High-impact work needs 48 hours of recovery. Fix: cap true plyometric and max-jump sessions at two per week.
• Skipping the arm swing. The easiest inches, ignored. Fix: drill the swing on its own until it is automatic.
• Testing fatigued. A tired test hides real progress. Fix: measure with fresh legs, never after a hard leg day.
• Chasing box height instead of takeoff quality. A tall box jump proves hip mobility, not power. Fix: prioritize an explosive push and a soft landing.

An 8-week plan to increase your vertical leap

Week	Focus	Sessions/week
1-2	Technique plus light strength, build the base	2 strength, 2 technique/light plyo
3-5	Add moderate plyometrics, raise strength load	3 strength, 2 plyometrics
6-7	Peak plyometric intensity, maintain strength	2-3 strength, 2 plyometrics
8	Deload roughly 40 percent, then retest	2 light sessions, then test

Keep 48 hours between plyometric sessions and never stack a heavy leg day right before one. Warm up 5 to 10 minutes with light cardio and dynamic mobility every session, and progress load gradually, since a sudden spike in volume is the most common cause of tendon trouble. If you are new to structured training, returning from injury, or managing a joint or heart condition, check with a coach or physician before starting.

When you’ll actually dunk

Dunking is a vertical target, not a separate skill: you need enough leap to bring your hand a few inches above the rim, which for most players means a running vertical in the high 20s to mid 30s depending on height and reach. If that is the goal, keep this program running and pair it with the ball-control and approach work in our guide on how to dunk a basketball. Increase the leap first, then rehearse the dunk itself.
