Before selecting a stretch for falling arms, what additional observation best examines shoulder mobility without masking trunk motion?
- AAllow lumbar extension so the arms reach overhead
- BElevate the heels and see if the arms stay up
- CObserve shoulder range with ribs and trunk held still
- DAdd a light dumbbell overhead to exaggerate the fault

Answer
C
Arms falling forward can be hidden by lumbar extension and rib flare; checking shoulder range while the trunk is controlled shows whether shoulder mobility is truly limited before a stretch is chosen.
A
Lumbar extension compensates for limited shoulder flexion and would mask the restriction the trainer is trying to see.
B
Heel elevation is a foot/ankle modification; it tests the influence of dorsiflexion, not shoulder mobility.
D
Adding load overhead increases compensation and injury risk without isolating shoulder range.
C
Arms falling forward can be hidden by lumbar extension and rib flare; checking shoulder range while the trunk is controlled shows whether shoulder mobility is truly limited before a stretch is chosen.
