Hey Jacob, 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!"- Steve B

"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. Thanks man!"- Patrick
"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."- Toni Burri, Lucerne,Switzerland
