You play a lot of basketball and you always wanted to dunk?

You want to increase your vertical jump, but you’re not sure which vertical jump training to chose?

Keep reading! I am going to share how I, an unathletic 29-year-old white guy, learned to dunk in just 4 weeks!

Let Me Introduce Myself!

Hi! I am Andy, a 29-year old basketball addict from Düsseldorf, Germany.

When I was little, my Dad mounted a basketball hoop to the garage in our driveway and I immediately fell in love with the game! I loved it so much, I shot free throws for hours even if there was snow in the driveway!

Some of my fondest childhood memories are my first dunks on that shaky little hoop - about 8 feet tall. So much fun! One day, I did my best Shaquille O'Neal impression and tore down the whole hoop with a violent tomahawk jam. ?

We replaced it with a solid, regulation 10-foot hoop and my driveway dunking days were over...

That's me:

  • ​Name: Andy
  • Age: 29
  • Height: 6' 0''
  • Standing Reach: 7' 11''

As a basketball player, I never got anywhere near professional level, but I always loved playing in different local leagues.

During my time at school and university, I was quite athletic. I wasn’t a high flyer, dunking over people in traffic, but I could grab the rim pretty easily and was a monster on the offensive boards.

About two years ago I did four weeks of the Jump Manual program with a friend. After that, I could flip in one or two dunks on a very good day. (Check out my detailed comparison of Vert Shock vs Jump Manual if you want to know more.)

If you have ever dunked a basketball, maybe even on a smaller basket, you know how great it feels. Since I was a kid, I have dreamed of being a high riser like Vince Carter or Lebron James. I wanted to rattle the rim consistently and with authority!

Unfortunately, once I got my first real job I did not have the discipline to hit the gym as often and I spent WAY too many evenings on the couch, eating potato chips and binging on Netflix.

My athleticism suffered. I got slower and less explosive every year. I was hobbling around like Tim Duncan—if Tim Duncan had zero knees instead of one. After last basketball season ended I was so annoyed by my lack of hops, I vowed to change!

I set one goal: To be able to dunk before I turn 30!

Sure, I wanted to improve my overall athleticism - to regain my first step. But, I really wanted to hammer the ball through the net (and maybe hang on the rim for a while).

Spoiler Alert! Watch this to see my results:

About the Vert Shock Program

In order to reach my goal, I had to find a good training program. So, one boring day at work I browsed the Internet searching for the perfect workout program. That's when I stumbled on Vert Shock.

The program promises an increase of 9-15 inches on your vertical jump in only 8 weeks. And to be honest, that sounded a lot like "Lose 20 pounds in 5 days" or “Make millions with no risk,” You see that stuff every day on the internet...

But, the web page looked very professional and made a 60-day, money back guarantee. So, I thought, “What do I have to lose?

Adam Folker and Kobe Bryant

The Vert Shock program was created by Adam Folker, a former college basketball player and now a professional basketball player, in cooperation with Justin “Just Fly” Darlington, perhaps the best dunker in the world. If you haven't watched have his mixtapes, make sure to find him. He's incredible!

  • What kind of shoes to wear
  • Correct jumping technique to maximize height
  • And other sneaky “hacks” directly from the NBA

The Structure of Vert Shock

The 8 week training program is divided into three parts:

1. Pre-Shock Phase

The Pre-Shock phase is the first week of the program. This week is going to "shock your body" and prepare you for the following weeks of the program. You will be working 6 out of 7 days. You rest on Day 4.

2. Shock Phase

Weeks 2 - 7 make the Shock Phase, the meat of the program featuring 4-6 workouts a week. These workouts range from strength exercises for your legs and core to jumping-specific movements to intense plyometric exercises.

3. Post Shock Phase

Week 8 is called the Post Shock Phase. It is a week of six very intense training sessions with only one day of rest. After seven weeks of training, you should be feeling a little stiff, so the warm-ups are very important.

The Vert Shock Exercises

Adam explains everything in high-resolution videos. Warm-up, cool-down, every exercise - everything you need to know.

The exercises do not require any heavy weight lifting, which is great for people without access to a weight room. Strength exercises are all performed with bodyweight or a basketball. The training program itself is available as a PDF and can be downloaded and printed or saved on any PC, mobile phone or tablet.

(Side note - full disclosure here, folks. I would have liked some more text explaining the background for the workout. I am a bit of a bookworm and I like to understand the theoretical foundation of workouts. I know this point won't be relevant to most readers, but if you are interested in a deeper knowledge about the mechanics and the training of the vertical jump, I recommend the book Vertical Foundation by Joel Smith.)

During the 8-week training program you will be doing 41!!! workouts in 56 days. These workouts are tailored towards different goals: 

  • Advanced plyometrics: Intense jumping specific exercises with an emphasis on short ground contact-times
  • Core strength: Planks and different static core strengthening exercises are important to prepare the body for high-impact jumping exercises
  • Power: Exercises like deep squat jumps increase the strength and power in your lower body which is very important if you want to increase your vertical jump.

The different focal points of the exercises allow different parts of your body enough time to rest between workouts. For example, you will never do two heavy plyometrics workouts on subsequent days.

When I first bought the program and had a look at the actual training program, the first thing that came to my mind was:

Damn that's a lot of exercises per week!

Truthfully, the workload is hard, but manageable. Just once after week 6 did I take a rest for two additional days because my body was feeling really tired and I wanted to prevent unnecessary injuries.

About Injury concerns

Before I started the workout I was really worried my knees would not respond well to the training program. I have had knee problems before, and at one time had to stop playing basketball for a while because I could barely climb stairs due to a strange stinging pain in my left knee.

Ironically, after the Vert Shock program, my knees feel better than before! For the first time in my life, I stuck to a stretching routine as part of the cooldown. I noticed I have a crazy shortened left quad. I put some extra work into loosening my quads and that has really made a big difference! I just wish I had known of the positive impact of stretching before - I always thought stretching would decrease my vertical, so I skipped it. (Stupid me!)

My Results of 8 Weeks of Vert Shock

Alright, let's get to the real interesting part! Does Vert Shock work?

Before Vert Shock (29" vertical)

In order to assess my improvements, I measured my vertical jump at the start of the training. I had a maximum jump of 29” (running). Not bad - I could grab the rim, so I had some hope.

Vertical Jump before Vert Shock

My Pre Shock Phase

Week 1 was one of the hardest weeks of training. After being a couch potato for far too long, my body was shocked by the six intense workouts in seven days.

Below you can see some pictures of the park where I usually did my workouts. This was surprisingly fun, and a great change of pace after sitting in a cubicle from 9-to-5.

As you can see, there are enough park benches of varying heights to do box jumps, depth jumps, etc. There is even a small hill for intense sprints!​

Overall, an average workout session took about an hour to complete. The workout included the dynamic warm up and the cooldown period! You won't need to spend hours each day working on your vertical jump.

Even though I had planned to take weekly videos of my progress, after Week One, I was just too tired to test my vertical. In retrospect, I think I was right - I doubt the results would have been pretty.

First improvements: Week 2 (32" vertical)

In Week Two, I was feeling a lot better, so I decided to use the day off to head​ to my favorite basketball court and take a few videos of some dunk attempts.

Two weeks of hard training had increased my vertical by 3 inches. I was very close to dunking for the first time in a while!​

The First Dunk: Week 4 (35" vertical)

Weeks Two and Three were pretty much business as usual. I kept working hard and my vertical jump increased steadily. When testing my vertical after Week Three, I was really close to dunking, but the ball just wouldn't go down!

On my way to the court after Week Four, I had the strong feeling that today would be the day. My legs felt strong and springy. It was hot (made warming up a lot easier) and I was pumped.

After doing my dynamic warm-up for 20 minutes and trying some jumps without the basketball, I picked up my basketball ball and tried some dunks. I think I missed the first three attempts, but I could feel I was incredibly close. On the fourth attempt, I crushed it!

I threw down my first dunk after only 4 weeks! The hard work paid off - and in a short amount of time. I had increased my vertical by over 5 inches in only 4 weeks! If I could continue this progress over the next 4 weeks, I could do some insane dunks!

Stagnation in Week 6 (35" vertical)

Until Week Five, everything went exactly as planned or even better. I increased my vertical jump each week and I was already dunking consistently with two hands. I could picture myself throwing down windmills, 360's and between-the-leg dunks! Winning my first dunking contest was only weeks away!

Unfortunately, my vertical jump actually decreased a little in Week Six. After 30 workouts in only 42 days, my legs felt really heavy and I was just beat.I decided to take a couple days off, and give my aching legs some well-deserved rest.​

The Final Push (37" vertical)

After my short break after Week Six, I went back to work with great enthusiasm. During Week Seven I was still not feeling great, but I was back to dunking easily even though my hamstring was really tight. Still, I wasn't as loose and explosive as I had hoped after my rest. I guess that’s the first sign of Father Time catching up with me. Five years ago, I would have been bursting with power after two days of doing nothing.

By Week Eight, autumn had arrived in Germany and it started to rain every day. I had to do a lot of the workouts of my final week in pouring rain - what a finish!

Fortunately, autumn also meant the school gym where my team practices opened up again. I was able to test my vertical on an indoor floor for the first time. The dirt and dust-free floor really helped, too. My vertical jump was up to a new personal record of 37 inches. I wasn't quite able to reach my ambitious goal of 40 inches, but I was damn close!

Final Vert Shock Results after 8 weeks

My teammates couldn't believe the way I was dunking! Three different guys asked me how tall I was. They couldn't believe a 6-foot white guy could dunk like that. ? After practice, I was throwing down alley-oops and trying all kinds of dunks with the tall guys on the team. (I am by far the smallest guy on the team who is able to dunk.) What a a great reward for all the hard work in the last 8 weeks!

And I am not an outlier! Others have seen the same amazing results. There is even a 5'5" guy who made his first alley-oop after Vert Shock. You need to see it to believe it!

[EDIT: 3 months after finishing Vert Shock ]

I was asked on YouTube and via Email if the increased vertical quickly vanished after I stopped doing Vert Shock. The quick answer: NO!

I haven't done a whole lot of jump-specific training lately, even though Vert Shock provides you with a maintenance program you can do once a week.

Still, I have been dunking a lot during and after basketball practices because it is just so much fun. So far I have maintained my 37" vertical. In fact, I am already planning my next round of Vert Shock in the upcoming off-season. I still want to reach my goal of a 40 inch vertical. I am stoked to throw down some windmills!

Final Thoughts

Overall, I recommend this program to every basketball player who is determined to increase his/her vertical jump. Not only will you jump higher, but you will also gain a lot of quickness and overall athleticism. Other parts of your game will also improve - rebounding, defense and penetration.

Vert Shock focuses heavily on plyometrics and is, therefore, especially suited for players who have no access to a gym or very little experience with weightlifting. All the equipment you need is either a basketball or a medicine ball. Download Vert Shock here, and you can start working towards your first dunk today!

Vert Shock Vertical Jump Training:

What I liked:

  • I can finally dunk
  • Great explanatory videos
  • No gym needed
  • Easy to follow program

What I didn't like:

  • No theoretical explanation of the workout


I increased my vertical by 8 inches during the program. I now have a 37" vertical and can dunk easily with two hands.


The original price is $134, but you can get it for $67 here. It's not cheap but being able to dunk was absolutely worth the price to me!


Every exercise is explained in great instruction videos. The printable PDF workout sheets are easy to read and no gym is needed!


The program is pretty time-intensive as there are about 5 workouts per week, each lasting a little less than 60 minutes. Exercises are demanding, but always manageable.

Vert Shock: Before and after 8 weeks of training

I have done it! 8 weeks of Vert Shock are behind me. I have made a first video of myself dunking on a basket in the gym we have played league games before. So it’s official: I can dunk on a regular 10ft rim! My teammates couldn’t believe their eyes!

Week 6

Vert Shock results after 6 weeks of training

There’s only two more weeks of Vert Shock ahead of me! But unfortunately after 6 weeks of Vert Shock I have hit a plateau and actually have regressed a little bit compared to week 5. My plan is to rest for a few days and then start the final push towards a 40 inch vertical!

Hey guys! Maybe you remember all that whining about how exhausted I was after week 1 of the Vert Shock system? Six intense workouts in seven days had really taken a toll on my body ...   So, you can imagine how glad I was that week 2 started with a day of rest for some very welcome recovery. And oh did I make the most of that day off, binging "BoJack Horseman" on Netflix and never leaving the couch once I was home after work 🙂 

Check out the video log of Week 2:

The program of week 2

Days 2 and 3: Jumping specific workouts:

After that lazy day off, the program took up where it left off before, with five (!!!) straight days of exercise. Day 2 and 3 were once again very jump specific. I think I have noticed a pattern by now, that these workouts usually start with very intense plyometric exercises which focus on speed and explosiveness and end with exercises that are more about strength like deep squat jumps.

If you don't know what plyometrics are: In short, plyometrics are exercises in which muscles exert maximum force in short intervals of time, with the goal of increasing power (speed-strength). This training focuses on learning to move from a muscle extension to a contraction in a rapid or "explosive" manner (wikipedia). The most popular example of such an exercise is the depth jump where you drop from a park bench or something similar, and upon landing try to explode back upwards as soon as possible with a focus on a minimal ground contact time.

4.5 / 5 stars (read more)

It make sense that these kind of exercises are scheduled at the beginning of the workout as they are very intense, therefore the central nervous system is heavily involved and fresh legs are very important. 

Day 4: Static core strength  

​Day 4 had an unwelcome surprise waiting for me. I was so happy last week that I didn't find any planks in the Vert Shock system. Turns out I was wrong! They are just called differently and are described as "Body holds". But hey, if it takes planks to throw down some vicious dunks in the near future then sign me up!

Overall, day 4 was focused on core strength with some more similar static strength exercises. You can absolutely do these exercises on a yoga mat in your living room in front of the tv, so the time commitment for this day is far less than for the jumping specific workout days. 

Day 5, 6 and 7: Sprints and explosive strength

I was already familiar with the workout of day 5 as it was also part of week 1. And I definitely saw some improvement as I was more comfortable with the exercises and my body by now is more accustomed this new kind of stress. The workouts of the second week concluded with some more jumping in day 6 and finally one more day of rest.

​First results:

Alright after that little diary entry lets get to the stuff thats really interesting! Does Vert Shock work? Has my vertical jump already improved?

As I was feeling a lot better this week than last week I decided to use the day off to head​ to my favourite basketball court and take a few videos of some dunk attempts:

Before Vert Shock

After 2 weeks


One legged jumps




Max running vertical 




As you can see in the video I am already really close to my first dunk in a long time. Especially if I could improve my technique on the two-footed dunk attempts a little bit, this could already be enough! So I am definitely happy about my improvements so far and cant wait to continue with the training!

I would be happy to see you again in a week! Who knows, maybe I can show you a dunk then? If you have any questions or suggestions just leave a comment! Cya next week!
