The Jump Manual is a famous vertical leap program created by Jacob Hiller. It is considered to be one of the top vertical jump programs in the world for various reasons. First and foremost, Jacob Hiller is an expert at vertical jump training. He is also good at explaining complex scientific principles in ways that anyone can understand. This makes his program very easy to follow. The program is also packaged extremely well. It is an interactive eBook with video. When you buy the book, you immediately get a link to download the program to your computer. This is a brief summary of what you will discover when you get the program: You will discover how to increase your vertical by mastering the proper mechanics of jumping. You will also learn how to combine rest and recovery with training. Finally, you will learn the reason why most people fail to increase their vertical jump, and the best exercises to jump higher. The program has a nice variety of fun exercises that are great for increasing your vertical jump. A bodyweight-only program is included as well, which is great for those who don’t want to lift weights. The Jump Manual workout is designed for one purpose only: to give you maximum vertical jump explosion. However, the main reason why the program is considered to be one of the best is NOT because it has new exercises you have never heard of before. The “Secret” is not in the exercises – because you have heard of some of them – but rather in how the program makes you perform these exercises. The Jump Manual shows you the CORRECT way to perform these exercises in the CORRECT dosage for maximum vertical leap gains. My favorite thing when it comes to the Jump Manual is the free one-on-one email coaching. If you have ANY questions or concerns, you can instantly reach Jacob via email or Skype. Very few vertical jump experts are this accessible, and it shows how much Jacob cares about your success. However, like anything in life, the program is not perfect. I had difficulties printing out some parts of the program, but this was the only ‘problem’ I experienced. The program also comes with 2 bonuses. The first is an interview with NBA shooting coach Dave Hopla, who regularly shoots 99% from the field. The second bonus is an interview with Peak Performance Psychologist Dr. Patrick Cohn. I’m sure you’re aware that a large part of sports is MENTAL, and Dr. Cohn will show you simple ways to get into the right mindset to crush your competition. In conclusion, the Jump Manual is a great vertical jump program. I highly recommend it to anyone who wants to increase their vertical jump, especially if they have previously failed with other programs.
