How can i improve my vertical?

These things that I am going to tell you about raise your vertical from 6-10 inches or more depending on how hard you work!!! The best thing is that they work!!!! They are called, ---------------------------Jump Soles ------------- Don't listen to the other answers those exercises only raise your vertical by 6 inches these really work. Look up Jump soles on the computer. Here is a picture of one. See these things do not have room for your heels so it forces you to jump without them and you can feel it more too!!! These things are amazing!!!! =] http://dsp.imageg.net/graphics/product_images/pG01-1882150p275w.jpg

Air Alert II it's a program (like a schedule) that you follow for 12 weeks. i've been told it's amazing, and i plan on trying it as soon as i recover from knee surgery! apparently it's awesome, so i'd look into it! here's a link: http://ck-ballaz.tripod.com/airalert2.htm

this is a good program that i found and i am using. http://www.ultimatehandbook.com/Webpages... it's free and uses everyday home items to improve leg muscles. other exercises that you could do are wall sits, leg press, calf raises, jump rope, squats, anything that involves jumping. try leg lifts too, they work on your hamstrings and abs.
