Coaching cues
- Feet wide for balance; one hand on the floor under the center of the chest
- Lower with full control; elbow stays tucked — not flaring outward
- The free hand rests at the small of the back or hip
- Resist the massive trunk rotation demand; body stays as square as possible
Common faults 2
Elbow flares out wide
The working elbow must track at 45 degrees; flaring stresses the anterior shoulder.
