Husband loves healthy walk (4,2)

I believe the answer is:

hoof it

'walk' is the definition.
(synonyms)

'husband loves healthy' is the wordplay.
'husband' becomes 'h'.
'loves' becomes 'oo' (love means 0 in tennis).
'healthy' becomes 'fit' (associated in meaning).
'h'+'oo'+'fit'='HOOF IT'

(Other definitions for hoof it that I've seen before include "walk" , "dance" .)

I've seen this clue in The Sunday Times.
