Side Lunge with Lateral Reach
Coaching cues
- Step wide into a lateral lunge; reach the same-side arm toward the floor
- Opposite arm reaches up and over — lateral stretch and lunge combined
- Drive back through the lateral foot to return
- Combines frontal plane loading with thoracic lateral flexion
Common faults 2
No true lateral reach — just a forward fold
The reach goes forward rather than to the side; thoracic lateral flexion is missed.
