Add the hinge pattern: Deadlift, RDL, Glute Bridge, Hip Thrust, Back Extension

The biggest hole in the coverage matrix - the hinge had zero entries in
any modality. Deadlift and Romanian Deadlift are the library's first
standing (camera.zoom) and first barbell motions.

# Romanian Deadlift
The stretch-focused hip hinge — push the hips back with soft knees until
the hamstrings stop you, then stand back up. Barbell or dumbbells.
- **Category:** Main circuit
- **Type:** Free-weight hinge (barbell or dumbbells)
- **Targets:** Hamstrings, glutes, spinal erectors
- **Prescription:** 3 × 810
## Setup
Stand tall holding the bar (or dumbbells) at the hips, feet hip-width,
knees unlocked. Set your shoulders back and brace.
## Execution
1. Push the hips straight back and let the weight slide down the thighs,
back flat, knees only slightly bent.
2. Stop when the hamstrings are fully stretched — usually just below the
knees — without the back rounding.
3. Drive the hips forward to stand tall again.
## Cues
- The hips travel backward, not down — this is not a squat.
- Weight stays close to the legs the whole rep.
- Feel the hamstrings load on the way down; that stretch is the exercise.
## Common Mistakes
- Bending the knees more as the weight lowers, turning it into a deadlift.
- Rounding the back to reach the floor — depth comes from the hips.
- Rushing the lowering phase.
## Progression
Add weight once the full stretch is reached with a flat back every rep;
single-leg RDLs for balance and asymmetry work.
