- Equipment
- machine
- Geometry

- Target feel
- Deep quad burn through full ROM — machine arc removes balance demand entirely.
- Progression
- Add weight once full-depth 3×10 is consistent.
- Regression
- Leg press or hack squat if pendulum machine unavailable.
Watch for
- Shallow depth — machines support full ROM, use it
- Heels lifting — move feet higher on platform
- Locking out with high spinal load — keep arch neutral
