Good to be included in naked jog (5)
I believe the answer is:
nudge
'jog' is the definition.
(I know that jog is a kind of nudge)
'good to be included in naked' is the wordplay.
'good' becomes 'g' (abbreviation).
'to be included in' indicates putting letters inside.
'naked' becomes 'nude' (synonyms).
'g' inserted inside 'nude' is 'NUDGE'.
(Other definitions for nudge that I've seen before include "Push; prompt" , "suggestive move" , "Push with the elbow" , "Jostle" , "Gentle poke with elbow" .)
