I’ve been called a wide variety of names over the past couple of years. These names have ranged from “guru” to “cheater.” Frankly, I don’t give a damn what people call me. The bottom line is that I get results with my athletes.

Some people admire this; others get jealous and choose to ridicule my methods. Some of my methods are mainstream and other times I have to dig into my bag of “dirty tricks” to get the desired result. Training athletes for the vertical jump test is no exception. I get more questions each week regarding the vertical jump than any other training topic. Most athletes seem to be obsessed with their vertical jump. This is where I come in.

Below you’ll find some of my favorite coaching “tricks” that I guarantee will improve your vertical jump. These underground techniques have helped over 2-dozen of my athletes jump over 35″ on this popular athletic test. Some may call these techniques trickery; others may call them smart coaching. Call them what you want, they work!

This dirty trick works so well it gives me chills! Well, not really but it’s damn effective.

Have you ever noticed that the day after you’ve performed a lot of jumping that your hip flexors were sore? I’ve personally pulled hip flexor muscles while testing my vertical jump. What I eventually figured out was that the rapid, full body extension that followed the rapid descent into the jump was tearing them up. After further analysis, one could conclude that if these muscles were getting torn up, that meant that they were probably resisting the height of the jump.

Hopefully we’re all well aware that static stretching isn’t recommended before any explosive activity. Static stretching your hip flexors before testing your vertical jump is the exception to the rule! You see, since the hip flexors aren’t prime movers in jumping and they tend to resist our jump, the goal is to weaken them and put them to “sleep” before jumping. Static stretching accomplishes these goals. Static stretching your hip flexors will create less friction during your jump. Less hip flexor friction during your jump equals higher vertical jump heights!

Below is one of my favorite hip flexor stretches, but go ahead and choose your favorite and perform 2 sets of 20-30 seconds on each side.

NOTE: The hip flexor stretch pictured below is a great stretch to perform before squatting as well. It will help you get deeper into your squats as well as prevent getting pulled forward during squatting. Give it a try!

The flexor hallucis longus is the least known of all the “jumping muscles.” Don’t get me wrong, this muscle isn’t going to improve your vertical jump as much as well-developed hamstrings, glutes, and spinal erectors; but this is an interesting muscle that can make a noticeable improvement in your jumping ability.

The flexor hallucis longus originates on the lower two-thirds of the fibula and inserts on the distal phalanx of the great toe. It plantar flexes the foot and also flexes the great toe. These muscle actions are an integral part of the vertical jump as well as sprinting. Getting this often-overlooked muscle stronger can be that added inch on your vertical jump that you thought was impossible.

The best way to train this muscle in the weight room is by performing single leg calf raises while holding a dumbell. (See pictures below.) When performing this exercise, try to keep most of your weight on the big toe of the working leg.


Crunching your toes in your sneakers/shoes while at work or school is another “economical” way of strengthening these muscles. Try 3-4 sets of 20 reps. No one will ever know!

Crunching a towel up in your toes while watching TV or working on the computer is another way to train these muscles without wasting any extra time.

Most athletes focus so much on the “jump” portion of jumping that they forget the importance of the descent of the jump. Through extensive research and observation, I’ve found that the speed of the descent is the most important factor in an athlete’s vertical jump height .

The bottom line is that the faster you can descend, the higher you will jump. Sir Isaac Newton’s 3rd Law of Motion supports this statement. It states that for every action there is an equal and opposite reaction . Knowing this, we can conclude that the faster we can descend into our jump, the faster we can take off. This translates into an explosive, jaw-dropping jump. Unfortunately, time and time again, I feel like I can go out to lunch and come back in the amount of time it takes an athlete to descend into his/her jump. If you want to jump through the roof, you must practice descending rapidly.

In order to perfect the descent, you must set up in the perfect position. Your vertical jump position should resemble that of an Olympic diver standing on a diving board. Your arms should be fully extended over your head, eyes looking upward to where you’ll be jumping, your back should be slightly arched and you should be standing on your toes. This position puts all of your muscles on stretch and sets you up for an explosive descent. Remember that an optimally stretched muscle can contract faster/harder.

Start the descent by throwing your arms down to your hips. As the arms fire downward, your head/neck will flex forward as your trunk and knees flex as well. In the bottom position, your hands should be slightly behind your hips, trunk flexed slightly forward and your knees bent at about 15-20 degrees. (Don’t get too caught up with the angle of your knees. Always remember that the angle of knee flexion is NOT as important as the speed in which you descend.) You are now ready to take off into a record-setting jump!

This is one of the dirtiest, sneakiest, and toughest exercises you’ll ever perform. It’s great for training the elastic component of your muscles along with the Achilles tendon.

I use 50-rep rhythm squats as a “peaking” exercise. My athletes perform this exercise once a week for 3 weeks before being tested in the vertical jump. The last “rhythm-squat” workout would be completed 4-6 days before being tested in the vertical jump. 50-rep rhythm squats would always be the first exercise of the workout. After a proper warm-up, you’ll perform one all-out set of this exercise. After this exercise is completed, I usually like performing another explosive exercise such as box jumps, push jerks, etc.

This exercise is done by performing 50 quarter-squats as fast as possible. Do the first 10 reps exploding onto your toes; then, on reps 11-20 keep your feet flat on the way up; explode onto your toes again while performing reps 21-30; keep your heels down for reps 31-40, and then finish the final 10 reps by exploding onto your toes again. It helps to have a partner count out loud so you can perform all 50 reps as fast as possible without breaking momentum.

I also like using a green Jump-Stretch band around the bar (see pics below) for two reasons: First of all, the band helps to accelerate the eccentric portion of the lift. This will further work the elastic component of your muscles and train your body to rapidly descend. Secondly, due to the explosive nature of the exercise, the bar has a tendency to bounce up and down on your cervical spine. This doesn’t tickle! The bands help to hold and stabilize the bar on your neck.

Proper shoe wear just might be the most overlooked component of the vertical jump. DO NOT wear an old pair of running sneakers because you feel that they’re “broken in” and comfortable. This type of sneaker is the worst thing you can put on your feet when jumping! These “comfortable” sneakers actually dampen the forces that you put into the ground. This, in turn, lengthens the time that you spend on the ground. Picture that as you rapidly descend into your jump, the foot collapses slightly and absorbs force. This dissipation of force can reduce the height of the jump.

I have my athletes wear light sneakers with a rigid sole and maximal arch support. This type of sneaker supports the first metatarsal, which is crucial to your jumping performance. I have found that track waffles are the best shoes for vertical jumping. Waffles are firm and very light. This allows for a rapid descent and take-off with maximal support. I also recommend that my athletes purchase waffles that are half a size too small. This prevents their feet from moving around in the shoe. Remember that these shoes aren’t meant for comfort; they’re meant for a world-class vertical jump!

Hopefully, this combination of training methods and “tricks” will have you jumping so high that you can grab a dollar bill off the top of the backboard and make change before descending. Okay, maybe that’s a little too ambitious a goal. Still, using these time-tested methods should have you jumping considerably higher than your current best.


  1. I cant believe after 7 or 8 years , nobody picks up on the fact that you are mistakenly using the word descend when you actually mean ascend…haha, descend is coming down, you cant descend into your jump but you can ascend into your jump or descend from your jump. Good luck man.
