A lot of younger players struggle with being strong with the basketball in the triple threat position. Even more with being able to rip through past a defender without losing the ball. This basketball exercise is going to specifically focusing on learning to develop that strong core in the triple threat position, and then learning to rip through to put the ball down past the defender, and attack the basket.
The resistance band is going to train your body to be even more explosive than it normally would be by tricking it, here is how it works. Your body must compensate for the added resistance of the band, and put out more energy and effort. When you take the band off though your body is still used to putting out the extra effort. However, there is not any resistance there anymore, so your body becomes quicker and more explosive. When you do your on court basketball drills involving the rip through motion, make sure that you are being explosive, and efficient with your movements that you learned from this exercise.
