Jack Cascio shows different depth jumps to increase vertical jump. If you have never done depth jumps you should start with shock jumps or a make sure you start with a low box depth jump. Depth jumps started back in the 80s by the Russians. It's no coincidence that they dominated all the Olympic sports. They were the ones doing plyometrics before anyone else. Plyometrics are key to a good vertical jump program. If you are looking to dunk a basketball then you need to be adding both plyometrics and strength training to all of your workouts.
