A good vertical jump doesn't require special footwear, years of training, or Dwyane Wade's genetics (though it definitely doesn't hurt). You can better your own skills—and get some serious air—by priming your body and boosting lower-body power.
With the following tips, you'll be able to out-rebound opponents on the court and maybe even rival the box jump feats of J.J. Watt in just a few weeks time.
1. Get the Knots Out of Your Legs
Muscle knots—also called "trigger points"—are everywhere in your body and restrict the length of your muscle tissue, making them shortened and weaker. Use a foam roller to relieve these spasms, focusing on moving slowly and stopping on tender spots until the knot releases. Work on each of the following areas for at least 30 seconds before switching legs:
Calves: Put the roller under your calf and rest your other foot on the floor (or cross it over the top of your shin to increase pressure). Roll from your ankle to your knee.
IT Band: Lie on your side with the roller near your hip and rest your other foot on the floor. Move the roller along your outer thigh. You can increase pressure by stacking your legs on top of one another.
Quads: Lie on your stomach with the roller placed under the front of your thigh. Roll up and down from the bottom of your hip to the top of your knee.
2. Do Bulgarian Split Squats
Your legs give you power to jump higher. (Another reason not to neglect your stems!) The Bulgarian split squat will help build strength, while improving your balance. To do it, stand a couple paces away from a bench, and place your non-working leg on it. The top of your foot should be on the bench. Hold a dumbbell in each hand and stand erect with your chest up. Descend until your back knee nearly touches the floor. Using the heel of your lead foot (the one that's on the floor), push yourself back up into a standing position. That's one rep. Try doing 3 sets of 8 reps on each leg on your lower-body workout day.
3. Practice Depth Jumps
A depth jump is performed by stepping off a box, then exploding up immediately after landing on the ground. This teaches reaction time and will help your lower body muscles activate when you need to catch air. Start by standing on a box that's 6 to 8 inches off the ground. Step off. As soon as you touch the ground, jump as high as you can, reaching your arms overhead. Land softly in an athletic position. Take a second to recover, then step back onto the box, set yourself up, and repeat. Follow this progression:
Week 1: 3x3 reps
Week 2: 4x3 reps
Week 3: 5x3 reps
4. Incorporate Knee-to-Feet Jumps
You're probably less familiar with this plyometric move: knee-to-feet jumps.
How to do it: Come down to your knees and sit back on your heels. Swing your arms to help create momentum as you explosively jump up, driving your hips forward and bringing your legs and feet directly underneath you. Brace your body as you land in a squat position with your arms out in front of you. Lower back to the kneeling position, coming down on one knee at a time.
This move produces more lower body power, and, when done in tandem with a sport-specific lifting regimen for six weeks, can boost your vertical jump, according to research published ahead of print in the Journal of Strength & Conditioning Research. In the study, 26 college athletes at Truman State University (participating in football, wrestling, softball, basketball, and track) saw improvements when they followed this protocol:
Week 1: Day 1 (test day), Day 2 (6x3 reps), Day 3 (5x4 reps)
Week 2: Day 1 (4x5 reps), Day 2 (3x5 reps), Day 3 (4x4 reps)
Week 3: Day 1 (4x4 reps), Day 2 (4x3 reps), Day 3 (3x3 reps)
Week 4: Day 1 (2x3 reps), Day 2 (3x2 reps), Day 3 (2x2 reps)
Week 5: Day 1 (4x3 reps), Day 2 (4x2 reps), Day 3 (3x2 reps)
Week 6: Day 1 (5x1 reps), Day 2 (4x1 reps), Day 3 (test day)
