Watch the elbow.
The crease closes and the handle moves toward the ribs while the seat is still traveling back. Forearms and shoulders may tire before the legs feel connected.
Early arm bend · Correction 01
Keep the handle connected to the leg drive without turning the first half of the stroke into an arm pull.
The elbow should stay open through most of the drive. The arm draw belongs near the finish, after the knees are nearly down and the body has begun to swing.
The crease closes and the handle moves toward the ribs while the seat is still traveling back. Forearms and shoulders may tire before the legs feel connected.
Hang from long arms until the legs have nearly finished.
A rower may grip hard, carry shoulder tension, or try to create power by pulling the handle. Heavy resistance and high intensity can make that instinct stronger. The goal is not to lock the elbows. Relax the shoulders and let long arms transmit pressure from the feet.
Early arm bend means the elbow angle closes materially while the knees are still completing the drive. It is different from the normal draw near the finish. Concept2 describes the drive as legs, then body swing, then arms; British Rowing similarly leaves the arm draw until the legs are nearly straight.
Reduce intensity while learning. If the sequence remains unclear, a qualified coach can compare what you feel with what is visible.
A camera can make a movement pattern visible. It cannot feel your connection, measure force, or replace an experienced coach.
From the side view, RowCoach receives pose landmarks and stroke timing while camera video stays on your device.
It compares elbow closure with knee extension across the stroke. Sensitivity is adjustable, so the prompt can match how strictly you want to practice.
Occlusion, clothing, camera angle, and landmark confidence can limit the estimate. A flag is a coaching prompt, not a diagnosis or proof that one stroke is wrong.
