Gym with place to sit (3)
I believe the answer is:
pew
'place to sit' is the definition.
I can't judge whether this definition defines the answer.
'gym with' is the wordplay.
'gym' becomes 'pe' (short for Physical Education).
'with' becomes 'w' (abbreviation).
'pe'+'w'='PEW'
Can you help me to learn more?
(Other definitions for pew that I've seen before include "Bench-like seat in a church" , "Long church seat" , "Where some of the flock rest" , "Long bench in a church" , "Part of flock sitting here" .)
