Did you see Rajon Rondo dunk on Jason Maxiell? What about his baseline jam on Vince Carter? Not only fans know that the Boston Celtic Rajon Rondo basketball quick. But most people don't even suppose he can jump that high.
Actually, standing at only 6'1'', Rondo is one of the best rebounding guards in the NBA as he grabs 5,3 boards per game. He's in fifth place this season (2008-2009), right behind Kobe Bryant, who is 6'6''. So it's obvious that the 22-year old Celtic can jump. His vertical might be in the 38-inch area. But the cool thing about vertical jump is that you can increase it with special exercises.
Now we all basketball heard about squats, calf raises and lunges. These exercises are good and will help to improve your vertical, but they might not be the most effective ones. For that, try some plyometric exercises, as they are designed to improve your explosiveness. And this is a crucial factor in the jumping process, as it's not only about muscle strength, but quickness. Here are two exercises that will boost your explosiveness:
1) Burnouts: Stand on your tiptoes. Now jump as quickly as you can about 1/2 to 1 inch off of the ground. Do about 50 repetitions per set.
2) Step ups. For this exercise you need a stable box or chair. Put one foot on the box/ chair that your thigh is parallel to the ground. Now use this leg to push yourself off of the chair and jump in the air as high as possible. Try to switch the legs in the air so that you land with the other leg on the box/ chair.
Another basic exercise that will improve your quickness are Wind Sprints (sprint for 60 meters, then rest for 20 seconds, 4 reps, 3 times a week). But those exercises are worthless if you don't know how exactly you have to do them and how many repetitions/ sets are effective. A lot of people are highly motivated and overtrain at the beginning. They simply jump too much and don't really care about proper execution of the exercises which is crucial. Doing so they only train their jumping endurance which is actually counterproductive if you want to improve your explosiveness. They don't really gain inches on their vertical jump and give up.
To avoid this, I can recommend the brand-new The Jump Manual, as you will find videos and pictures inside that guarantee a proper execution of the exercises
