"I recommend the Jump Manual to any athlete who is serious about maximizing their quickness and vertical explosion. I have seen the program work time and time again. It's an intense regimen but there are tremendous gains to be had."

"I tried everything man! Air Alert, Strength shoes, plyos you name it I tried it. Your program made sense and I gave it a shot. I gained 13 inches in in 12 weeks and now I can 360 dunk with 2 hands. Every time I play people always notice. I recommended to our coach that the whole team does the work-out cause i'm also a whole lot quicker. Seriously... Thanks!"

"What I was most surprised about the training program was how little time it took each day to get those kind of results. 2 weeks after doing the training I was jumping higher. I was quicker and dunking easily. My training will never be the same and I would recommend without hesitation to all my team mates. Thanks again."

First of all I just want to say your Jump Manual is awesome-it's the real deal. I couldn't agree more with your training methods. I don't want to bore you with my life story... I was hell-bent on being able to dunk-it became an obsession. I bought training manuals like yours-but those that taught me to do hundreds and hundreds of repetitions. Being used to working my butt off in the gym these workouts worked me hard and I figured for sure that they'd work for me, but I saw only little improvements. I then bought [The Jump Manual] ... I went from having a hard time grabbing rim with one hand with a running start, to being able to grab with two hands with a 3-4 step start. I was surprised and glad that I was improving, but far from content. I have a HUGE reach advantage... I really appreciate it.. Thanks a million "
"Hi Jacob, I showed your workout to my coach (former coach of the Czechoslovakian National team volleyball) and he told me it looks good, but if I wont get any results in the first month, then i have to stop. Ive done your workout for two weeks now and Ive already gained 3 inches!! If I continue doing progress like that, I can move from libero to an outside hitter. Thanks man.'

"Hi Jacob, I'm 19 years old and i've been playing basketball all my life. When I was eighteen I reached a plateau on my vertical jump, no matter how much I trained or all the exercises my coaches gave me, I couldnt go an inch higher. I was stuck at a 32 inch vertical. After reading your program and doing the exercises for just two weeks I've increased my jump 5" already, your approach to vertical jump training has already given me a great advantage and I hope it will continue doing the same.
"I could only barely dunk a volleyball from a running start. Now I can stand under the rim and dunk a basketball with 2 hands, it's freakin nuts! I recommended the program to my entire team!"

I wanted u 2 check this out, dunno if u can use it as a sort of testimonial, but i used ur program and this happened..."
PUBLISHED IN NEW ENGLAND RECRUITING REPORT:
Like any all-star type game, Tuesday night’s action featured its fair share of highlight reel plays. But there was a 20 second span in the midst of the junior game that was by far the night’s most entertaining. It began when Cromwell’s Isaiah Salafia streaked down the middle of the court with Windsor’s Ishmael Kalilou being the sole defender back to protect the basket. Salafia elevated, and so did Kalilou, but the mid-air contact was just enough to allow the Cromwell star to stay air born and throw down a two handed dunk over the top of his would-be defender.. the crowd went nuts...
Isaiah Salafia – His explosive dunk wasn’t the only thing to like about his game. He’s a prototypical slasher who has become consistent enough with his jumper to keep defenders honest. He’s a big reason why Cromwell is one of the pre-season favorites to take the class S state title.
- Isaiah Salafia
"THANKS FOR YOUR GREAT PROGRAM. I USED TO WORK OUT WITH STRENGTH SHOES ONLY,AND GOT VERY LITTLE RESULTS.WITH YOUR PROGRAM I HAVE THE HIGHEST VERTICAL ON MY TEAM AT NOVA SOUTHEASTERN UNIV.IM 6'1" AND I HAVE A 31' VERTICAL JUST FROM WORKING OUT FOR ABOUT 2MOS OVER THE SUMMER.ILL SEE U HIGH ABOVE THE RIM!"
- John Brooks
The jump manual has been going awesome, I have definitely felt lighter and my vert is improving weekly. Thank you for sending me this video, a lot of great tips that I will look to keep in mind. I'll send you some dunk videos in a month or so that will show my progression. Thanks and keep the bomb videos coming.
IT'S BEEN ONE WEEK SINCE I STARTED DOING THE JUMP MANUAL WORD 4 WORD AND MY VERT HAS INCREASED. I WENT FROM TOUCHING THE BOTTOM OF THE RIM TO GRABBING IT IN ONE WEEK!!!!!!!!!"
- Ricardo R..
Wow! This is a great manual! Gaining momentum now and feels like the old days. This works and I have only just started. After the first workout I knew this was a tremendous no nonsense program. After just two weeks committing myself I have gained 6" and this is only the beginning. Really feeling stronger and more explosive. I am excited.
Thanks for all your help! "
i mean to be honest since i've been doing the wieght training mixed with ploymetrics i've seen a great increase in my veritcal i've been doing things i've never done before....just the other day i threw the ball off the wall caught it and dunked it with my right hand....not to mention i wasn't warmed up and i'm left handed so everthing that you've said concerning increasing my vertical a great deal not to mention my overall game....i'm being asked to play all over at this point between leagues schools etc....so i greatly appreciate all the help"
After receving this unsolicited email from Tremayne I emailed him back:
Excellent, thanks for the updated. Any idea how many inches you have gained? I'd like to add this as a tesimonial...
"6 inches and counting every week i'm seeing a difference in my game as far as my scoring ability the endurance and strength that my legs have during the course of the game. just this past thursday on the 18th i had a game where i had a fast break dunk that made the crowd go bananas and an alley-oop that made the crowd get wilder than that, normally during the course of the game my legs would get tired...to tired to even attempt a dunk, but now i can play both both halves or all four quarters without have exhausted legs.... speaking of basketball i'm actually about to go work out now....sorry for the long message... thanks again for all the help and advice i appreciate it"
"EVERYBODY GET THIS PROGRAM. i went from a 30 to a 35 in the first month.

"Thank you for sharing your videos. I just dunked for the first time today! :D"

I just wanted to say thanks for the Jump Manual. I tried it out for nine weeks and I gained about seven inches!"
Hi, since you told me to keep you updated about my progress, I think I should now do it then.
So first I am 19 years old, I thought maybe its significant and I am 183-184 cm tall and I weigh 78-79 kilograms. I measured my vertical leap before I started working with the Jump Manual, I got 61.5 cm (couldn't properly touch the rim without an approach back then).
After the first week working with Jump Manual on Sunday I measured it again and I got about 65 cm (basically I touched the rim without an approach)
I've seen the improvement and it feels great! In general, when I play I now feel like I would be lighter or something.
I have been averagin one inch per week on my vertical. I have already gone from nicking the rim to easily hanging on it. I can't wait to dunk.
Thanks to you i have increased my vertical by at least three inches and i am the only seventh grader in the district who can touch the rim. If you keep this up I'll be dunking in eighth grade- thanks. "

I already have purchased the jump manual program and absolutely love it. The program is showing me results beyond what I expected and for what I'm using this for; to be able to get up and spike/block better than almost everyone in my indoor volleyball league and to stay quicker/jump higher than the other guys I play pick up basketball with, well, it's definitely working. I've been recommending this to friends and thanks for such an awesome program."
This is Tanner [omitted last name]. I got the jump manual a little while ago. I really hit it hard right after i got it because i got it when school was out and i am super impressed. I've already gained 3 inches. in the first 2 weeks and i have never gained that much before. I'm looking forward to the following weeks.
Thank you for the manual."
- Tanner W.
I have the program and just letting you know I layed three dunks down
in practice two days ago and I cant even palm a ball! my running vert already went from a 36 to 42 [inches] and my standing went from about 30 to 37 [inches]. Looking forward to the following weeks of the program."
- John E.
hey i just wanted to say thanks for your program its helped alot I've gained 7 inches in my vertical and 5 in my first month and i dunked for the first time. and now i can grab the rim the two hands i just need a couple more inches to dunk consistently. your program has been great thanks.
- Coleman F.
Quick update. I've been doing the jump program now for about 3 weeks and have already seen a noticeable improvement... I'm pretty stoked with the results I've seen. A couple days ago after a decent warm up I was dunking with one hand consistently... was able to get fingers around the rim before, but never enough clearance to get the ball in there. I'm looking forward to continued improvement!
I don't know if this is really Jacob or someone that works with him. I purchased the jump manual late summer for my 15 year old son Tanner. He was just starting football. At the beginning of the program, he measured his vertical at school at 27in. At that time, he could "touch" the rim on occasion if his legs were warm, running off one leg. We have only done 6 weeks due to basketball season starting. At the very beginning of basketball, they measured his vertical again. His vertical is now 31in. He can jump off 2 feet and grab and hang on the rim with either hand. He will begin the program again after basketball and do a full 12 weeks. He is excited about his progress to-date.

"Hi J. it is me again.
Alessandro the little italian dreaming of slamming...listen: since the last time i contact you i increased my vertical at amazing 10 cm. all in all 16 cm. So i am so proud and i have to thank you again. i am 170 cm tall (or small) and this 16 cm for me are so important as a little pointguard in my league... Looking forward to the following weeks.
If i really dunk one day i will name my son Jacob...
"Thanks. You're really good trainer. You don’t want just money like others on internet. And those trainers also didn’t give you the proper exercise to increase your vertical like you. Thank you again.
"I did the first to weeks and now I can Jump 2 Inches higher Thank you your workout is great I will continue it on Monady.
Thank you for the work YOU have done in researching and preparing The Jump Manual. I used the workout for 3 weeks, sticking to the schedule as best as I could. I am 6 feet tall, and from just three weeks of your workout, I was able to dunk two handed.I now know your program works and I can't wait to continue with the Jump Manual.
- Richard L.
oh my goodness in 2 days... I already gained 1and a half inch!!!!!! I dunno how 2 thank u!!! 2 days!!!!! this is phenomenal!!!
- Toni L.
"I really appreciate all your detailed responses and in such a timely fashion. I am glad that there is someone that knows what their doing and can sell an affordable program.
. After using your workout before the start of the season for only 5 weeks, I gained 5" in my vertical. I just completed my high school volleyball season. We did very well, taking 2nd in state. Now that the season is over I will finish the workouts."
I received the updated version of your jump manual. I think it is fantastic that you have made it available to past customers. Thanks so much!
As far as results go I was seeing fantastic results. I didn't track inches but I was starting to get that "hanging" ability in the air. Where I was on the way up still as others were on the way down. Never really had it before. In a pick up game a guy actually reached down and said he was checking my shoes for wings. So I know it was working. Only thing is I haven't had a chance to give it a fair shake. I'll start incorporating your routine again soon.

"Hey, I finally dunked on my basketball hoop the other day for the first time in my life. It's so cool and one of the greatest feelings and I'm glad to have all of the hard work pay off so quickly.
Anyways, I'm going to keep on working at it so I can throw down some harder dunks.
Thaks a lot and Merry Christmas,"

"I really gained a lot from this program. I can Jump higher and sprint faster. I am a star player in our volleyball team because of this, for the fact that I can spike stronger . Really, who can imagine that a 5 footer can spike like a 5'9. Seriously . Thank you very much. What I am now is because of this."
- Dunking Amazon
First, I'd like to thank you for your products and videos. It really seems like you're out to help people in their ever ongoing struggle to find gains. I appreciate that you are giving it your all. Producing new videos, being so available to your customers, and having a general helping attitude, is all really extra to what you've already provided. And that is something no other jump program comes close to."
"hey what up i just wanted to thank you for making me the best basketball and only player to dunk in my grade."
- Lloyd B..
I am just starting The Jump Manual. After reviewing the section on improved jumping form I went outside and did something I have never done before. I jumped up and grabbed onto a 10ft ring with two hands off two feet. This is a huge accomplishment for me and I am so excited to get started on the program. I am telling my friends all about the program. Just wanted to say thanks for the program and for always responding quickly to all me questions."
- Konrad C.
I have to say it is well worth the price u offer to your customers. I can already dunk off the dribble. Another benefit of your training was the increased speed i had that propelled me to a 40 yard, 70 yard touchdown receptions. I am only in 10th grade but now I start on the varsity team. I am the only one that can dunk on my team and i am 5'11. Today I had 19 points. 4 of them were on offensive rebounds where I completely jumped over the 3 defenders around me and went up strong. Another basket I had was on a fast break against a 6'4 guy. I saw him loading for the block, me just made a move round another defender knew in this situation i wouldn't get higher then him because of his height. I jumped up put my hip into his body and hung in the air longer than him to receive an easy and 1. That really hyped up my team as we won 77 to 47. I've scored on many lay ups by just soaring above the defenders. I scored 27, 11, 16, and 19 in my scrimmages so far. Thanks for the program."
"In a short time I have already gained 4 inches higher... It has helped me so much that even other players have noticed the diff. Your program is an excellent tool for ppl who are wanting to reach their vertical potential. Thank you so much.
- Rick H.
I did your explosion exercises as explained in the book and it really worked, i have gained 3 inch vert already in two weeks."
