P's out of training? (4)
I believe the answer is:
soft
'out of training?' is the definition.
(thesaurus)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for soft that I've seen before include "Cushy, not tough" , "(Of drink) not alcoholic" , "Gentle - simple" , "Velvety" , "Yielding; quiet" .)
