## What is Kyna?

Kyna turns barbell movement into meaningful performance data.

Using a dedicated barbell clip, Kyna measures acceleration during your lifts and gives immediate, objective feedback on how the bar moves. See acceleration over time, force output, and performance trends across sessions without guesswork or lab equipment.

Review every lift in a clean, searchable history, compare performance across weights and exercises, and track progress over time. Built for athletes and coaches who care about intent, consistency, and measurable improvement.
