http://www.youtube.com/watch?v=FzyaOut_QxA this guy is quite good.How to increase? Mainly stretch stretch and stretch again every day and jump jump a lot of time. It helped myself a lot.

Thank you! . In Slovakia, it is probably night time.

I need to jump higher

My mistake, I was very tired, that I forgot time zones, but maaaan I am from Slovakia not Slovenia ?

why he has to naked chest, when he gives info about vertical? :-D
Its not recommended doing exercies without clothes. You have to keep your body warm and clothes do that mainly your upper parts.

I know, that some videos on youtube are quite overreacted. I dont want to say, this guy is bad, ofcourse he gave perfect info and examples, but to our young Wilfredo from USA is better, if he learns, that he has to do exercises dressed and not naked ?))

Thank you, Berny from Slovakia!
