i just made a trial and error of me trying to dunk. and i just want to inspire those guys who want to increase their vertical leap. I am only 5'7 and still i cant dunk on my own. i made this for you guyz out there.. just keep believin' and you'll end up successful in every aspect of your life. P.S. negative comments on this video will be deleted. Song used: I believe i can fly - r. kelly
