Rowing · Layback at Finish
torso (shoulder → hip) vs. vertical at the finish, expressed as degrees past vertical.
What good looks like
At the finish, the torso has swung past vertical by 10–15°. The legs are flat, the handle is at the lower ribcage, and the elbows are tucked past the body. The spine is long — not collapsed — and the head and chest are stacked above the hips. The athlete should look settled, not "thrown" back.
Why this matters
Layback converts back-swing range into handle distance. Each degree of layback adds roughly 2 cm of stroke length at the handle — across a 1000 m piece, the difference between 5° and 15° of layback is ~3 m of effective stroke length per pull, which over 240 pulls is 720 m of free distance. That's most of a 1000 m row.
But layback is double-edged. Excessive layback (past 20°) loads the lumbar spine without adding distance — the shoulders are already past where the rib cage can usefully transmit force to the handle. It also slows the recovery: every degree of extra layback is a degree the body has to pivot back through before the slide can move forward.
Common faults
- No layback (< 5°) — finish position is too "tall". The athlete finishes the drive sitting upright; the back never did its job. Confirm against Body Angle at Legs-Down and Trunk at Handle-Past-Knees — likely the back stayed locked through the entire drive.
- Excessive layback (> 20°) — usually "thrown" with the head leading. Common at high stroke rates when the athlete is racing the legs back to the catch and over-corrects with the back. Sets up a slow, late recovery.
Coaching cues
- "Finish strong, not laid out." 10° feels like sitting back into a chair, not lying down.
- "Stop the back at 11 o'clock." Visualises the layback as a clock hand — 12 o'clock is vertical, 11 o'clock is the target.
Related measurements
- Elbow Flexion at Finish — together they describe the full finish position.
- Chain Level at Finish — a high handle finish often pairs with excessive layback.
- Trunk at Handle-Past-Knees — the back should be visibly mid-swing by then, on its way to this layback target.
