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 Curl
|
||
|
||
The free-weight biceps curl — elbows pinned to the sides, curl both
|
||
dumbbells from a full hang to the shoulders.
|
||
|
||
- **Category:** Main circuit
|
||
- **Type:** Free-weight elbow flexion (dumbbells)
|
||
- **Targets:** Biceps, forearms
|
||
- **Prescription:** 3 × 10–12
|
||
|
||
## Setup
|
||
|
||
Stand tall with a dumbbell in each hand at your sides, palms forward (or
|
||
turning as you curl), elbows lightly touching the ribs.
|
||
|
||
## Execution
|
||
|
||
1. Curl both weights up in an arc until the forearms reach the biceps.
|
||
2. Keep the elbows fixed in place at your sides.
|
||
3. Lower all the way to straight arms — the stretch counts.
|
||
|
||
## Cues
|
||
|
||
- Elbows are hinges, not swings — they never travel forward or back.
|
||
- Wrists stay neutral; no flicking at the top.
|
||
- Stand tall; the trunk does not rock.
|
||
|
||
## Common Mistakes
|
||
|
||
- Swinging the hips to start the rep.
|
||
- Half reps that skip the bottom stretch.
|
||
- Elbows drifting forward, turning it into a front raise.
|
||
|
||
## Progression
|
||
|
||
Add weight only while the torso stays statue-still; alternate arms or
|
||
curl seated to remove all momentum.
