Basketball training regime

[madhops22]

Are there any basketball players out there? Even better, are there any pro trainers out there? I need some help...I want to add 8 inches to my verticle jump by June...If you could give me tips on what exercises I should be doing, etc I would appreciate it. Also, how do you "train yourself to jump higher"? I know there is a psychological aspect in jumping, how is it done? I see all these advertisements in basketball magazines saying that they can help you improve your jumping abilities...I don't want to spend tonnes of money on something that could be a fraud.

Any help is much appreciated!
