The decision
When this movement makes sense
The 2 documented configurations use One fixed dumbbell or One adjustable dumbbell and budget 85–100 seconds for setup before sets and rest are counted.
When this changes
If any required condition —a bench or support approved for the upper back— cannot be confirmed, or the available load does not match the recorded configuration, the engine chooses another movement instead of improvising.
