What makes a grip
count.

The ten rules

1. 1

   Approved device only

   Every score is set on a league-issued Camry EH101 digital hand dynamometer, calibrated and handed to you by the hostess. Personal grippers, spring devices and anything not handed to you on the floor are void.

2. 2

   Peak mode, one hand

   The unit is reset to zero and set to peak-hold in front of the camera. Your strongest hand, whichever it is. The other hand stays away from the device and your body.

3. 3

   Stance and grip

   Stand upright, feet planted, elbow at roughly 90 degrees, upper arm relaxed at your side. The handle sits across the middle of your fingers with the display facing outward toward the camera.

4. 4

   The 60-second window

   From the countdown ending you have 60 seconds to name yourself and deliver one maximal squeeze of 3 to 5 seconds. One squeeze per token — not a best-of-three.

5. 5

   No bracing, no swinging

   No pressing the unit into your thigh, hip, chest, a table, a wall or the other hand. No jerking, dropping the arm, throwing the shoulder or crushing on the way down. The arm stays free and still.

6. 6

   The wrist lift

   You release pressure but keep holding the unit. The hostess takes your wrist and raises your arm so the screen faces the lens. Nobody touches the buttons.

7. 7

   The reading shot

   The camera closes in and holds on the display until the kilogram figure is sharp and steady for at least two seconds. That frame is the score. No reading on camera, no score.

8. 8

   The thumbs up

   In the same unbroken clip the hostess looks into the lens and gives a thumbs up, confirming what she saw from a metre away. No thumbs up, no attempt.

9. 9

   One clip, no edits

   Name, squeeze, wrist lift, reading and thumbs up must be one continuous recording. Cuts, speed changes, screen recordings and re-uploads are void.

10. 10

    You, in person, 18+

    The competitor on camera must be the signed-up account holder, over 18, and visible in frame with their face. No proxies, no stand-ins.

What gets you thrown out

• The reading is never shown clearly on camera
• The clip is cut, sped up, edited or filmed off another screen
• Two hands on the unit, or the free hand braces the arm
• The device is pressed against the body, a table or a wall
• The unit was not zeroed on camera before the squeeze
• No hostess in frame, or no thumbs up
• Somebody else's hand or face is on the attempt
• A device that is not league-issued
• The figure jumps beyond what the video shows — the AI flags impossible spikes
• A repeat squeeze on the same token to chase a better number

How we audit the board

Disputes and arbitration

If you think a score is wrong — yours or somebody else's — there is a set process, and it is the only one.
