Ex-prisoner given word of encouragement for keeping in trim (7)
I believe the answer is:
parolee
'ex-prisoner' is the definition.
(prisoner on parole)
'word of encouragement for keeping in trim' is the wordplay.
'word of encouragement' becomes 'ole' (Spanish exclamation).
'for keeping in' is an insertion indicator.
'trim' becomes 'pare' (synonyms).
'ole' put into 'pare' is 'PAROLEE'.
'given' acts as a link.
(Other definitions for parolee that I've seen before include "One conditionally released" , "One is released on conditions" , "Person no longer inside" .)
