basic-advanced stretching methods

Hi. Newbie to fighitngarts. i've been practicing multiple styles of martial arts, none of which have been in a class, and i decent for being my own teacher. what i'm wondering is this: stretching to promote higher and more powerful kicks, especially roundhouses-stretching to do better backflips and front- stretching for better balance at lower points, horse stance, leg sweep, etc. if anyone can reply soon, PLEASE DO! thanks in advance if necessary.

All the answers are in posts on this forum and at www.stadion.com.

I would recommend 'high power kicks with no warm up' - available from stadion, to help with kicks. as for backflips - no idea, I'm no gymnast!
