Pulls in stomach muscles following end of liposuction (4)
I believe the answer is:
nabs
'pulls in' is the definition.
(I've seen this in another clue)
'stomach muscles following end of liposuction' is the wordplay.
'stomach muscles' becomes 'abs' (abdominal muscles).
'following' says to put letters next to each other.
'end of' says to take the final letters.
The last letter of 'liposuction' is 'n'.
'abs' put after 'n' is 'NABS'.
(Other definitions for nabs that I've seen before include "Catches with bans" , "Snatches" , "Does appropriate" , "Catches in the act" , "Arrests" .)
