DunkNow Original Program

DunkNow Shock

Shock Your Body to Get Stronger and Jump Higher

One reason why DunkNow surpasses anything on the market is what we call the "DunkNow Shock." The "DunkNow Shock" is the time in the program when you make the transition from the first phase of the program to the second phase.

During this uniquely designed interval, the heavily researched group of exercises exert a pressure on your muscles and your body. This pressure is 100% safe and forces your legs and body to adapt and get stronger very quickly.

The group of exercises complement one another and the "DunkNow Shock" effect takes place.

100% Money-Back Guarantee

Our Guarantee: Jump 10-20 Inches Higher or Your Money Back

We are so confident in our vertical jump program that we guarantee an improvement of at least 10 inches on your vertical leap.

To stand behind our claim, we will guarantee a 10-20 inch increase on your vertical jump that you will jump higher to athletes who purchase the DunkNow Program, master the exercises, and most importantly, stay committed to the program. If you put time and effort into the program and happen to fall in the unfortunate 5% who don't meet the 10-inch improvement, DunkNow will refund the full price of your program.

*New Extended Guaranteed:

If you can currently touch the net on a regulation 10 foot hoop, we guarantee that you will dunk within 6 months.

DunkNow Testimonial

Inches Gained on Vertical Jump: 15.5

"I tried the DunkNow Jump Program and it really does what it promises. I went from touching the net before I started the program to grabbing the rim within a month, then after 4 months I was dunking a volleyball. Within the 5th month I dunked a basketball on a regulation size 10 foot hoop.

I could not explain the feeling when I threw it down. DunkNow is amazing and everyone should check it out."

Oh yeah and I can do a windmill dunk!
