Hammer thrower exercises in village (6)
I believe the answer is:
thorpe
'village' is the definition.
(I've seen this before)
'hammer thrower exercises' is the wordplay.
'hammer thrower' becomes 'Thor' (the Norse god Thor wields a hammer).
'exercises' becomes 'pe' (Physical Education).
'thor'+'pe'='THORPE'
'in' acts as a link.
(Other definitions for thorpe that I've seen before include "Village" , "Aussie Pools winner" .)
