In athletics, the vertical jump can make the difference in grabbing a rebound, spiking a volleyball or making a catch. The vertical jump is used in just about every sport, and is trained for using a variety of exercises ranging from resistance training to plyometrics. Some professional sports organizations even use the vertical jump as a marker for drafting a player or signing a contract. The vertec provides an easy and accurate system for measuring a vertical jump, and is the common choice for many sports organizations, including the NFL.

Set up the vertec on a stable surface with enough room to be able to jump and land in a safe position without hitting any other objects or landing on an uneven surface.
Measure your reach using a tape measure against a wall. Try to reach as high as possible to eliminate any inaccuracy between reach and vertical jumping ability.
Raise the vertec so the bottom peg is exactly 10 inches above your reach.
Even all of the pegs facing outward away from the vertec using the vertex stick.
Set yourself underneath the pegs.
Jump as high as you can from a standing position. Do not take a step or use a running start to jump as it will lead to an inaccurate measurement of your vertical jump.
Move as many pegs as possible and land safely after the jump. Do not swat at the pegs because you are more likely to miss or not hit the pegs at your highest point. Simply reach out as far as you can while jumping to move the pegs.
Push all of the pegs you moved and any peg below the highest peg you moved to the inside of the vertec. Straighten the remaining pegs.
Continue Steps 5 through 8 until you are unable to touch a peg during your jump.
Count the number of pegs you moved during your jumping. Each peg represents 1/2 an inch of a jump. So if you moved 15 pegs, for example, multiply 15 by 1/2. Add the result of 7.5 to the initial 10-inch difference between your reach and the bottom peg, and you get 17.5 inches. This is your vertical jump.
