I decided a little over a month ago that I wanted to dunk. When I first walked onto the court and jumped as high as I could, I was in for a rude awakening -- I was about 2 or 3 inches below clipping the rim, and I'm 6'0. So I started trying to get myself in shape.
For the past month I've been doing weighted calf raises (40 pound dumbbell in hand, balancing against a wall, on one leg, 4 or 5 sets of 8 - 12 reps), one-leg squats (bodyweight, 5 sets of 5 - 6 reps), and I've also just practiced jumping a lot, by touching the rim as much as possible, as well as any 10 foot ceilings I come across.
Sometimes I do both the calisthenics/weightlifting and the jumping practice on the same day, but I always take at least a day off in between workouts with the raises and the squats, and I stop vertical jumping at the rim when I start to get sore in the joints (usually after a day or two).
Here's an example week:
Monday -- Jump high as much as possible
Tuesday -- Jump some more, squats and calf raises
Wednesday -- rest
Thursday -- rest
Friday -- squats and calf raises
Saturday -- jumps
Sunday -- jumps
Somewhat haphazard.
I gained inches really fast the first two weeks on my program, but I haven't been able to grab the rim yet, I've only gotten my fingers about an inch above it at most.
Is there any muscle group I am neglecting? Are the weights I'm using appropriate? Anything I'm doing wrong? Any advice is greatly appreciated.
