Yup , ive followed his youtube vids and read some articles on his site in the past.
He seems to know his stuff and the training principles are correct: Heavy lifting to build up strength , plyos + explosive lifting to transfer it to vert.
What bothers me is that his site is over-marketed , full of "buy me" links and testimonials , its getting a bit ridiculous. But he's gotta make a living , im not the one to judge how he does that.
All in all , i have not read his program but i think he is legit and his program works.
