Having a higher vertical jump will help you avoid problems of being pulled harder due to gravity. Gaining some inches of vertical leap will imply a significant deviation of dunking and spiking.
Before anything else, you should understand that the main aspect of all vertical leap training programs is safety, which includes prevention of injury. The moment that you get yourself hurt, everything that you worked hard for will eventually disappear. Try to do your best in training, but avoid going over your body’s limit.
Never think that you will have a significant increase on the first day of training. Always make it a goal to go for consistent and viable vertical gains. Do not try to go over the backboard on a little less than two weeks of training, you will most likely get injured.
Maintain good concentration on strengthening you body’s core when you are serious to increase your vertical jump. Furthermore, your abs, hip flexors, and quads should be given importance because they have a major role in gaining an explosive vertical leap.
