The Story
Her coach shouts the same corrections every session: stop rushing, sit up, finish clean. She hears the words but cannot translate them into movement. She does not know what shooting the slide feels like from the inside — only that she keeps being told she does it. The gap between verbal coaching cues and motor learning is where most technique correction fails.
This is a composite portrait. The story reflects patterns documented across many athletes. No individual is depicted.

What the Research Tells Us
"Every fault has a root cause, and it is almost never where you see the symptom. Fix the cause, and the symptoms disappear."
— Noah Wickliffe, Flowbase Performance Series
Kleshnev (2020) classified rowing faults into two categories: primary faults (root causes) and secondary faults (compensations). Shooting the slide, for example, is typically a secondary fault caused by insufficient leg connection at the catch — the legs straighten but the handle does not move because the trunk is not engaged. Correcting the trunk engagement at the catch resolves both the primary and secondary fault simultaneously. Greene et al. (2013) used 3D motion capture to quantify common rowing faults and found that overreaching at the catch (exceeding optimal catch angle by more than 5 degrees) increases lumbar flexion by 15–22% and reduces effective stroke length because the additional reach is absorbed by spinal flexion rather than increased arc. The correction is not reducing reach but improving pelvic rotation to achieve the same angle with a neutral spine. Smith & Loschner (2002) analyzed blade path faults and found that washing out (blade exiting the water before the finish position) reduces effective stroke length by 8–12 degrees and is the single most common fault at all levels of rowing. Skying (blade too high above the water on the recovery) and digging too deep (blade fully submerged past the blade depth) both relate to handle height control and grip tension during the recovery phase.

Fix the cause, and the symptoms disappear." — Noah Wickliffe, Flowbase Performance Series 15–22% Lumbar flexion increase from 8–12° overreaching Effective length lost from washing out Cause correction vs. symptom chasing
How the Flowbase AI Coach Helps
The AI Coach distinguishes root causes from symptoms — eliminating the guesswork that makes traditional fault correction so frustrating.
The Flowbase AI Coach uses computer vision to identify faults in real time, trace each fault to its biomechanical root cause, and prescribe corrective drills in the correct sequence. It tracks fault frequency across sessions, showing whether corrections are holding under fatigue and higher stroke rates. The AI Coach distinguishes root causes from symptoms — eliminating the guesswork that makes traditional fault correction so frustrating. Fix Your Faults Upload video from any angle.
