render.py --export bundles the 25 new motion rigs and info pages; figure-fixtures.json regenerated for all 47 (the Swift solver reproduces every new motion, including negative-y pins and the new prop uses). The fixture count assertion moves to 47, and the no-bundled-motion test now uses Treadmill - a permanent COVERAGE.md exclusion - since Bench Press exists. 48 tests green; watch target builds. Coverage handoff complete - TODO-coverage.md retired. Claude-Session: https://claude.ai/code/session_01HJDQQDA9QdP8zByg43H5v3

# Dumbbell Row
|
||
|
||
The one-arm row — knee and hand braced on the bench, pull the dumbbell
|
||
from a dead hang to the ribs.
|
||
|
||
- **Category:** Main circuit
|
||
- **Type:** Free-weight horizontal pull (dumbbell)
|
||
- **Targets:** Lats, mid-back, biceps
|
||
- **Prescription:** 3 × 8–12 per side
|
||
|
||
## Setup
|
||
|
||
Put the same-side knee and hand on a bench, the other foot planted on
|
||
the floor. Back flat and parallel to the ground, dumbbell hanging
|
||
straight down from the shoulder.
|
||
|
||
## Execution
|
||
|
||
1. Pull the dumbbell up and back toward the hip until the elbow passes
|
||
the ribs.
|
||
2. Squeeze the shoulder blade at the top.
|
||
3. Lower to a full hang and stretch. Finish the set, then switch sides.
|
||
|
||
## Cues
|
||
|
||
- The elbow leads; the hand just holds on.
|
||
- Shoulders stay square to the floor — no twisting to hoist the weight.
|
||
- Long neck, eyes down; the back stays flat.
|
||
|
||
## Common Mistakes
|
||
|
||
- Rotating the torso open at the top of each rep.
|
||
- Pulling with the biceps instead of driving the elbow back.
|
||
- Cutting the stretch short at the bottom.
|
||
|
||
## Progression
|
||
|
||
Heavier dumbbells while the torso stays quiet; pause each rep at the top
|
||
for a stricter mid-back stimulus.
