I scoured the Internet looking for guidance. There are dozens of sites promising a path to dunking, most of them coded at the dawn of the Web. It was daunting finding one that seemed legit. I ended up paying $67 for the Jump Manual, an online program offered by Jacob Heller, a trainer with a 42-inch vertical who counts NBA players among his clients, according to his website. Next, I ordered a pair of Strength Shoes. You’ll remember these if you’re a basketball player of a certain age—the ridiculous-looking training kicks popular in the ’90s, with a platform under the toe that places your bodyweight on the balls of your feet.


The boundary for stopping the trial owing to the lack of evidence of a difference between treatments at a P value of 0.05 was crossed (Figure 5 in the Supplementary Appendix). There were no significant differences between the groups in the rate of death at 28 days or in the rates of death in the ICU, in the hospital, at 6 months, or at 12 months (Table 2). Kaplan–Meier curves for estimated survival showed no significant differences in the outcome (Figure 2). Cox proportional-hazards analyses that included the APACHE II score, sex, and other relevant variables yielded similar results (Figure 6 in the Supplementary Appendix). There were more days without need for the trial drug and more days without need for open-label vasopressors in the norepinephrine group than in the dopamine group, but there were no significant differences between the groups in the number of days without need for ICU care and in the number of days without need for organ support (Table 3). There were no significant differences in the causes of death between the two groups, although death from refractory shock occurred more frequently in the group of patients treated with dopamine than in the group treated with norepinephrine (P=0.05).
This is a high quality gear set for the next generation recoil shock series.  They only use one gear set through out the entire range, so this will fit all NEXT gen guns. This is a extremely well made piece of kit, This is possibly one of the strongest gear sets on the market, i would say the main benefit over other gear sets is its tuning option, you can by it in both single torque which is a little over the standard gear ratio and the double torque which is a lot over the standard ratio. Both provide increased torque up on the gun ie less effort to turn the spring, which in turn gives you increased battery life and and faster trigger response, sacrificing a little ROF. Although technically they should see a decrease in ROF because of the ratio, ive actually seen increases in ROF because of how efficient these gears are and because they are balanced.  Expensive gears but a very awesome piece of kit if these where cheaper they would no doubt be in ever ones guns.. no exceptions.
Stand on your right leg and lift your left knee up as high as you can. Keeping your knee bent and your left leg out of the way, jump and land eight to ten times on your right leg. Focus on the landing. Your body should be ready to spring back up again the second you hit the ground. Try to jump higher with every repetition. Use your left hip and raised leg to build leverage.

Independent 6'2" North American athlete Eric Bishop introduced a dunk entitled the 'Paint Job'. The title is in reference to the key on a basketball court, often known as 'paint' in common parlance.[36] Approaching along the baseline with a running dribble, Bishop jumped with one-foot at the border of the key, dunked with one-hand while gliding over the key and landed just beyond the border on the side opposite his take-off—a 16-foot flight.
At pickup the next night, buoyed by the previous day’s accomplishment, I found a regulation ball that had good grip, one I could palm, and in between games, when no one was looking, I dunked for the first time in eleven years. If some dunks are described as thunderous, this one could be best described as a gentle fart in the breeze. But a dunk’s a dunk—and I had dunked.

When approaching your dunk, run up with tall form and on your toes. People tend to lean forward to gain speed, this is wrong. Lean back and you will see the difference. Also when running, start off slow then gain speed into the jump. Never slow down. When you are at the poin to jump, take small strides and don't drag your foot. You want to have your front leg straight with your entire body. Again, stay leaning back some. Explode up. Keep practicing this technique. I am doing it and i went from a 32" running vert to a 38". that is how much form can do with your Dunk. (NOTE: this is for one legged jumpers)
Less helpful was my early realization that I was a two-hand dunker, in light of my inability to palm a basketball on the move. It’s common knowledge among dunkers that throwing down with two hands is typically harder than with one; the former requires a higher vertical leap. So as I flailed haplessly at the rim last spring with one hand, I felt not just discouragement but also fear. Fear that I would miss big chunks of my kids’ ninth, sixth, and first years on earth just so I could come up embarrassingly short on a senseless goal that my wife and I would later estimate consumed 15 to 20 hours a week, on top of my normal work hours. And fear that I had shared this idea with my editors way too soon.
The method described above is the most common and simplest way to measure one's vertical jump, but other more scientifically accurate methods have been devised. A pressure pad can be used to measure the time it takes for an athlete to complete a jump, and then using a kinematics equation (h = g × t2/8),[4] the computer can calculate his or her vertical jump based on the time in the air.
