Passing
Zach Kahan's first pass at pre-movement — the frame the analysis measures.

THUMBS
The same pass at contact, the ball meeting the platform.

What you get back

Verdicts, not decimals.

A number tells you nothing you can act on. Every measurement comes back the way a coach would say it — one of five verdicts, from a strength to the thing to fix first.

Arm-swing · Elbow high and back
The elbow's position at Set — high and behind the shoulder, the loaded position the whip comes from.
Major strength
High and back every rep — the whip comes right through the arm.
Strength
High and back on most reps.
Solid
Holds high on most swings, drops when you tire.
Needs work
Often drops below the shoulder, which costs the whip. Keep it high and back.
Needs a lot of work
Drops on nearly every rep — high and back is where the whip comes from.

Coach's notes
"Ready position is really good. Form the platform with the arms more in front of you, and shrug your shoulders. You will then be able to track the ball with your platform."

into one instruction for tomorrow.

Coach's Notes
Your coach’s read, written against what it is about — one rep, several, or the session as a whole.
Note 1 of 5 · on Pass 3
“Consider widening the stance so that you have a stronger base, thus allowing the contact point to be lower.”

Why us

Built by an elite-level player and coach.

Not by engineers who researched volleyball technique. Every ideal in the system was set by someone who has played and coached at that level, and validated against data, rep after rep. That is the standard your session is held to.

"Better to see yourself once than hear a hundred times."
— and the reason feedback exists
