Re: Swaggin, I need your help
Check out the "by july 3rd next year, i will be dunking.." thread, he's helped me out with a lot of stuff and there's plenty of info there about increasing your vertical. Another one is the "training plan" thread, he's helped me there as well.
You can definitely do it by next year, 2-3 inches below the rim, you might even be able to do that in a couple months. What's hard is not to train, but not to overtrain. If dunking is your sole goal, I wouldn't bet against doing it in ONE month. But you'd have to forget about basketball... and start dieting.
Here's the science: to jump your highest, you need to be light and powerful. So you'd need to eliminate all unnecessary fat and muscle and just jump. But if you don't want to go that intense than 3 months will easily get it done if you do it right.
Just ask if you have any questions.
