a lot of young players want to be good players and great Dunkers such as Michael Jordan, Kobe Bryant, Vince Carter ... To get them not only have great technique, but also a good fitness preparation and a great vertical leap that will allow them to dunk and get the crowd on their feet.
A lot of people think that when dunking the most important thing is the height, but they are wrong. There were many small players in the NBA who are able to dunk. Just mention Spud Webb, who was only 5ft 7 "(170cm) tall, but he won the NBA dunk competition. His dunks are amazing working elevator two-handed double pump dunk, one arm of the backboard with one hand jam, a 360-degree helicopter one-handed dunk, etc. Many people who are 6feet 6inches (200cm) tall can 't do dunks like this one, a This just shows us how the vertical jump is really important.
In order to improve vertical jump, you have to combine 2 things training and rest. When you train people to feel the tension in the muscles and this makes them thing that increases muscle, which usually makes people want to train harder and more often, but it gives poor results. Because during the training breaks down muscle and after training when the muscles begin to rest and repair that build them. You should always keep in mind that the muscles do not build up during training bud after training. And here comes the second important thing, food. If you want to build muscle fast you need to eat lots of proteins that are found mostly in meat.
so that they could play and dunk well you have to train your vertical jump, rest and eat lots of protein.
