This is a guest post by Andreas Rauh. He writes about basketball and vertical jump training on WhatsMyVertical.com, and also documents his vertical jump training on his Youtube Channel.

At 6ft tall, I was always a pretty athletic basketball player, I could grab the rim easily and on a really good day (and on lower rims) I could even squeeze in a dunk from time to time. But in the summer of 2015 I decided to go for it, I wasn’t getting any younger and I wanted to know just how high I could jump if I really worked hard on it. And so my obsession with vertical jump training began!
