Some players thinking jumping off two feet to be more comfortable, but it’s different for every player. Take time while you’re practice your jump to find what’s the most comfortable for you. As you’re learning the right way to jump, comfort is crucial because you don’t want to hurt yourself making a move that feels awkward. You want to be comfortable taking off and landing - and that can be done a number of different ways.

After a one-week recovery period in January following Phase 1 of Jump Attack, Phase 2 brought an increase in intensity and time investment. This was the last stop before Phase 3, the wilderness where those attack depth jumps lived. (Attack depth jumps: Rest on your knees in front of a box; explode to your feet without using your hands; immediately jump onto the box; immediately jump as high as you can off the box, landing on the balls of your feet. Repeat. Many times. No blacking out allowed.) Phase 3 brought dramatic increases in both explosiveness and hip flexibility, two critical ingredients that I started to feel working in tandem. I emerged both confident and in dire need of another one-week recovery period, which I spent playing with our kids, watching dunk videos and mouthing the syllable Ow. Once healed, in early March, I returned to the rims with a friend whom I’d asked to toss lobs to me. There would be no more lifting. (After Jump Attack, what else could there possibly be?) From here on, I just jumped and recovered, jumped and recovered, attacking this tiny window of three or four weeks before my time away from the gym began to sap my strength. It would be over at that point, all over, whether I wanted it to be or not.

The vertical jump is defined as the highest point that the athlete can touch from a standing jump, less the height that the athlete can touch from a standing position. The measurement of the jump is flawed if the athlete is permitted to take one or more steps before jumping, as the athlete will convert some of the energy developed in the step taken into the force of propulsion that generates upward lift. Basketball has numerous legends and other urban myths concerning the seemingly superhuman leaping ability attributed to certain players; one such player, former University of Louisville star Darrell "Dr. Dunkenstein" Griffith, was reputed to possess a 42 in (1 m) vertical leap. It is likely that the average National Basketball Association player 6 ft 6 in (1.97 m) or shorter has a vertical leap of between 25 and 30 in (0.63 and 0.75 m); taller and heavier players will usually not be able to jump as high.

Step 2. Nudge the bar out of the rack and step back, setting your feet at shoulder width, with your toes turned slightly outward. Without letting your feet actually move, try to screw both legs into the floor, as if you were standing on grass and wanted to twist it up—you’ll feel your glutes tighten and the arches in your feet rise. Take a deep breath into your belly and brace your core, pulling your ribs down so your torso forms a solid column.

IMPORTANT NOTE: Feb 2, 2019 - I am currently updating the site to have all the articles on the same format and also shooting new HD videos of the exercises in the library. For the duration of the this update I am selling Game Changers at an 80% discount (YES YOUR READ THAT RIGHT - 80% OFF the regular price). Instead of paying $47 you can pick up a copy of just $9. But hurry - this offer will be gone once I finish the updates.

Keep your upper body straight and your arms relaxed at your side. Extend your left leg straight out behind you with a slight knee bend. Place your right leg in front of you with your knee bent at a 90-degree angle and your thigh parallel to the floor. This is your basic lunge position. From this position, slightly lower your entire body, and jump to the opposite lunge position with your right leg extended behind you and your left leg in front of you. Repeat 25 jumping lunges in a row for three sets with a 1-minute break between sets.
I found out that if you practice penultimate two-step jumping practice dunking or just jumping, it gives a MUCH better workout than any one step jumping practice. I was also able to increase my one foot jump vertical by this. I think 2-step dunking is much more powerful and waaaaaay cooler. It is also much safer because you are in more control of your body. Right now I'm 6'1" and can 2-step tomahawk and basically everything off one foot
A great summary of what it takes to improve vertical jumping ability Joe. There is definitely an art and science to optimizing vertical jump height. I actually just completed a huge post on the topic of How To Jump Higher which your readers may find complements this post nicely. It is a long read (12000+ words) but for those of your readers who want to learn more about the art of jumping they may find it helpful. Keep up the great work!
Keep that in mind, and progress slowly. A mini basketball is a little more challenging than a tennis ball, but it's easy to palm and that helps. See if you can get high enough to get your hand over the rim--almost up to your wrist--so you can stuff the mini ball. If you can't throw it down with a little authority, a bigger basketball won't be any easier.
An important component of maximizing height in a vertical jump is attributed to the use of counter-movements of the legs and arm swings prior to take off, as both of these actions have been shown to significantly increase the body’s center of mass rise. The counter-movement of the legs, a quick bend of the knees which lowers the center of mass prior to springing upwards, has been shown to improve jump height by 12% compared to jumping without the counter-movement. This is attributed to the stretch shortening cycle of the leg muscles enabling the muscles to create more contractile energy. Furthermore, jump height can be increased another 10% by executing arm swings during the take off phase of the jump compared to if no arm swings are utilized. This involves lowering the arms distally and posteriorly during the leg counter-movements, and powerfully thrusting the arms up and over the head as the leg extension phase begins. As the arms complete the swinging movement they pull up on the lower body causing the lower musculature to contract more rapidly, hence aiding in greater jump height.[5] Despite these increases due to technical adjustments, it appears as if optimizing both the force producing and elastic properties of the musculotendinous system in the lower limbs is largely determined by genetics and partially mutable through resistance exercise training.[6][7]
