I sat out during gym being this? (4,2)
I believe the answer is:
past it
If this is the answer I cannot explain how the clue works.
Can you help me to learn more?
(Other definitions for past it that I've seen before include "undrinkable?" , "Too old for task - gone too far" , "No longer competent" , "Spit at, being too old or decrepit" , "Far from fresh" .)
