How to Determine the Dominant Core Performance Zone

The first step is to determine the Dominant Core Performance Zone. It is a simple process. Each person has an 8 inch Performance Zone. Once you determine their Performance Zone you can do the Wright Balance® Express on one of the 11 Stance Widths within their Zone. The Performance Zones are predictable 8 inch Stance Widths.

This video shows how to determine the Performance Zone (PSR). Then it shows the importance of setting the order of the Kinetic Chain in all activities.

This video shows an Upper Core Player, Colby determining his Performance Stance Width Range (PSR) after his Core Zone is determined.

Question

In this video I demonstrate how to find the Dominant Core Zone using:

a. A coffee cup
b. A dumbbell
c. A Wright Balance bat
d. The thumb of the lead hand & the middle finger of the trail hand.

Answer

a. A coffee cup

Question

How does a coffee cup help determine the Dominant Core Performance Zone?
a. The coffee cup magnifies the impact of grip size and core rotation is greater when not in the Dominant Performance Zone
b. The coffee cup is a distraction so your student will relax and allow the Core to rotate when out of balance
c. Your student will be able to maintain hydration during a lesson
d. The coffee cup or any large cylindrical object is a "tool" to use when you are not sure if the player's hips are rotating

Answer

a & d

Question

True /False
To use the Coffee Cup to observe hip rotation, your student should take the cup in one hand, grip the cup holding it so all the fingers of one hand are around the cup and THEN step into one of the Stance Widths of each Performance Zone

Answer

False (read the last sentence again)

...grip the cup holding it so all the fingers of one hand are around the cup and THEN step into one of the Stance Widths of each Performance Zone

Note: The Lower Kinetic Chain (Stance Width) MUST be set before the Upper Kinetic Chain. Only hand the player a cup AFTER they assume their stance.

Question

In the video, Colby picks up the dumbbells before he sets his stance in his known Performance Zone (PSR). How does this impact his Core
a. There is no impact
b. His weight moves toward his toes
c. His pelvis rotates
d. He describes his weight moving to his right heel

Answer

c & d

Again, this video shows an Upper Core Player, Colby determining his Performance Stance Width Range (PSR) after his Core Zone is determined. This questions that follow are based upon this video. If you miss the questions that follow, please review this short video.

Question

Which of the following Stance Widths should you use in testing the Dominant Performance Zone (PSR)?

a. 10 inches; 14 inches; 19 inches
b. 10 inches; 18 inches; 26 inches
c. 8 inches; 14 inches; 25 inches
d. None of the above

Answer

b. 10 inches; 18 inches; 26 inches

Note: The video shows Colby testing the Lower Core at 25 inches. The Range for Lower Core is 20 inches (plus or minus 1 inch) to 28 inches (plus or minus 1 inch). Colby's height permits a wider base for testing. For players with shorter legs use 22 or 23 inches when testing the Lower Core Performance Stance Range (PSR)

Question

If my student sets their feet at 18 inches and THEN takes a large cylindrical object (cup) in one hand, what Performance Zone am I testing?

a. Upper
b. Middle
c. Lower
d. None of the above

Answer

b. Middle

Question

What is the Performance Stance Width Range (PSR) for the UPPER Core?

a. 6 inches (plus or minus 1 inch) to 14 inches (plus or minus 1 inch)
b. 10 inches (plus or minus 1 inch) to 18 inches (plus or minus 1 inch)
c. 8 inches (plus or minus 1 inch) to 16 inches (plus or minus 1 inch)
d. None of the above

Answer

c. 8 inches (plus or minus 1 inch) to 16 inches (plus or minus 1 inch)

The Wright Balance® Express Using Only Power Spots

This video shows how to set the Power Spots on the lead thumb and middle finger of the trail hand.

Question

What did the various grip sizes on the bat do when gripped during the original Wright Balance Express?

a.The size of the bat is all that was needed to recruit each of the Core Zone grip sizes
b.The bat handle recruited the various Core Zones regardless how it was held
c. Pressure was applied to the middle fingers of both hands of the corresponding Core Zone Stance Widths
d.None of the above

Answer

c. Pressure was applied to the middle fingers of both hands of the corresponding Core Zone Stance Widths>

Question

What finger of the lead hand and what finger of the trail hand are pressed together applying pressure as the Wright Balance Express is done?

a. The thumb of the lead hand and index finger of the trail hand
b. The middle finger of both hands
c. The thumb of the lead hand and middle finger of the trail hand
d. None of the above

Answer

c. The thumb of the lead hand and middle finger of the trail hand

The following video shows how to do the Wright Balance® Express using Power Spots on the thumb of the lead hand and the middle finger of the trail hand.

NOTE: This video was shot in early January, 2026 before testing the Wright Balance® Express while covering the NON-DOMINANT Power Spots on the trail hand. Covering the NON-DOMINANT Power Spots on the trail hand during and following the Wright Balance® Express has been tested and concluded with 100% accuracy on 47 subjects with completion January 28, 2026. When the non-dominant Power Spots on the trail hand are covered with tape during and following the 2 minute Wright Balance Express, the persons hips are square from 0 inches to 40 plus inches or as wide as they can get their feet. The player is also square in all other planes of motion.
