If any bball players are serious about basketball they should read the vertical jump bible many times and find out what you need either weight training or plyometric training!!!!! and of course since i can tell that none of us are playing on the nba we all need weight training. I used to be able to dunk about 3 years ago and all i did was plyometrics like jumpsoles and airalert but i was skinny no body or muscle and i was very weak i weighed around 155lbs and i suffered many rolled ankles and near injuries so i stopped doing them right now i began weight training and i currently squat 1.5 times my body weight i am 5' 11'' and weigh 180lbs and i can hang from the rim i am trying to either get down to 170 or 175 depending how i feel about my quickness and strength, well anyways my ultimate goal is to squat 4 times my body weight but that will take me many months if not a year and a half but its doable. I recommend all of you to start squatting and doing deadlifts ur first goal should be to squat and deadlift 1.5 times ur body weight and then 2 times and so on. I will start doing plyometrics after i squat and deadlift 4 times my body weight.
