Mechanics
- Pattern
- hinge
- Equipment
- barbell
- Geometry
- 120° Hinge Angle
- Energy model
- Glycolytic Pathway (10-90s)
- Target feel
- Deep hamstring stretch mid-descent; erectors brace isometrically throughout.
- Progression
- Add load slowly; use as a warm-up accessory, not a primary lift.
- Regression
- Bodyweight good morning or Romanian deadlift with lighter load.
Watch for
- Rounding lower back — high spinal injury risk
- Bar too heavy — always a technique exercise
- Knees locked out — reduces hamstring stretch range
Substitutions
- Romanian deadlift
- B-stance RDL
- Nordic curl
