Warm up together, already matching.
Simple elements, identical execution across the line.
Skate in a line and hold even distance without looking down.
One element, filmed or watched by a coach, for honest feedback.
Train the matched skating that makes a line look like one skater: same knee bend, same extension, same timing. Watch your neighbors, not your own feet.
