How to Dunk

How to Increase Your Vertical Jump

Have you ever wished you could dunk? Of course you have. Who wouldn’t like to throw down a dunk during a pick up game or an actual game? If you search for answers though, you’ll see all kinds of opinions on how to increase your vertical. Here we’ve compiled the most effective things you can do to increase your vertical jump according to research.


1. Swing your arms:

First, let’s start off with technique. Swinging your arms while taking off has been shown to increase your vertical jump by 10% (compared to not swinging your arms). Another study found that the added benefit was 28%.


2. Bend your knees:

This is probably obvious, but bending your knees before taking off increases your vertical jump by an average of 12% (compared to not bending your knees).


3. Lose Weight:

The more you weigh, the more force you’ll need to generate to jump the same height. One study followed wrestlers and judo athletes who lost an average of 5 kg. (11 lbs.) over 3 weeks. Their verticals improved by between 6% and 8% over that time period. So, be sure to add in some cardio and eat well.


4. Olympic Lifting:

Olympic style lifting involves explosively lifting weight in exercises such as the snatch and the clean and jerk. This contrasts with traditional power lifting which involves moving much heavier weight at necessarily slower speeds. One study found a 15 week Olympic lift program increased verticals by 15%, while the verticals of the power lifting group increased by less than 1%. Another study found more modest gains for Olympic lifting over power lifting. Here’s the training schedule in that study in case you are interested:

vertical program

Another study demonstrated that kettlebells could be an adequate replacement for barbells and dumbbells. It had participants train twice a week for 6 weeks with either kettlebells (kettlebell swings, accelerated swings and goblet squats) or weightlifting (high pulls, power cleans and back squats). Both groups improved their verticals, but there was a non significant difference between the groups.


5. Squats:

One specific exercise that has been shown to increase verticals is the squat. One study showed that participants who did a squat program for 10 weeks increased their vertical jump by 8%. Another study found a non-significant difference in a 7 week program of deep squats, parallel squats, or loaded squat jumps. So, the type of squat doesn’t seem to matter as much as you might think.


6. Deadlifts:

Another specific exercise is the deadlift. One study found that participants who did barbell deadlifts twice a week for 10 weeks increased their vertical by 7.4%.


7. Power Cleans:

Power cleans are another effective exercise. One study found that as a participant’s power clean maximum increased, so did their vertical jump. Those who increased their power clean by 0- 20 lbs. increased their verticals by 3.66 cm. An increase of between 20 to 45 lbs. led to a 3.89 cm vertical increase. A power clean increase of between 45 and 60 lbs. led to a 6.5 cm. vertical increase. Finally, those who increased their power clean by more than 60 lbs. increased their vertical by 9.5 cm.


8. Plyometric training:

Maybe not surprisingly plyometric training (or jump training) has been shown to increase verticals. A meta analysis that looked at 26 studies found that plyometric training increases vertical jumps by between 4.7% and 8.7%. Another meta analysis found that a higher intensity plyometric training program (at least 50 jumps per session) worked better than lower intensity programs. Specifically, using a combination of jumps like squat jumps, drop jumps and countermovement jumps was most effective. Yet another study found that a 7 week plyometric training program increased verticals by 3.81 centimeters, a squat program increased verticals by 3.30 centimeters, but plyometric and squat training increased verticals by 10.67 centimeters. So plyometrics is definitely something you should consider adding to your weight lifting.


9. P.A.P.:

Post Activation Potentiation is when you follow strength training with an explosive movement. So you might do 5 back squat reps then do squat jumps afterwards. One study found that participants who did a single back squat (at a weight that was 80% as much as they could possibly do) and who held a half squat for 6 seconds improved their vertical jump by 10%. But, the effect dissipated after about 12 minutes. Looking more long-term, another study found that using plyometrics and strength training in the same training session was effective, but the exercise order didn’t matter.


10. Stretching

One study found that static stretching of the hamstring significantly improved vertical jumps. Stretching the hip flexors, dorsiflexors and plantarflexors also had a positive impact, but the effect was much smaller. That being said, learning how to unlock hip flexors does have many other benefits when it comes to vertical jumps. It can be an important part of any warmup because it will help to prevent injuries such as pulled muscles or lower back pain. Another study, though, found that dynamic stretching is more effective than static stretching in improving verticals jumps.



In summary, improving your vertical involves proper technique, a combination of weight lifting and plyometrics along with cardio and a proper diet to aid with weight loss. Most importantly, you need patience. The results won’t come overnight.

If nothing else, hopefully this will encourage you to not skip leg day.
