Labour excluded from government training session (7)
I believe the answer is:
workout
'government training session' is the definition.
I can't judge whether this definition defines the answer.
'labour excluded' is the wordplay.
'labour' becomes 'work' (I've seen this before).
'excluded' becomes 'out' (I've seen this before).
'work'+'out'='WORKOUT'
'from' is the link.
Can you help me to learn more?
(Other definitions for workout that I've seen before include "A session of physical exercise" , "Vigorous exercise session" , "healthy practice" , "Vigorous PE session" , "Bout of exercise in gym" .)
