Like gym user, MD accepting bad clues? (7)
I believe the answer is:
muscled
'like gym user md accepting bad clues?' is the definition.
I can't judge whether this defines the answer.
'md accepting bad clues?' is the wordplay.
'accepting' means one lot of letters goes inside another (inserted letters are accepted).
'bad' is an anagram indicator.
'clues' is an anagram of 'uscle'.
'md' going around 'uscle' is 'MUSCLED'.
Can you help me to learn more?
(Another definition for muscled that I've seen is " brawn?".)
