I've made great gains on my vertical in the past. I started with low 20" standing. Now I have 29" standing, 34" running 2 step and 36" running one step.
I am in football, basketball, and track (high and long jump). My goals for vertical by end of junior year are 34" standing vert, 40" running two step, and 42" running one-step.
I will be beginning a program by one of my track coaches. I will be olympic lifting of some sort about every day, and squats, and other exercises (not deadlifts though). Football is starting up, and then bball, and then track without much break in-between. It will be quite a challenge, but it's better to set standards too high than too low!
In addition to jumping higher I also want to be able to do a full planche pushup, and a full front lever pullup, along with other bodyweight skills like handstand pushups and various levers.
