In excellent health all right (4,4)

I believe the answer is:

very well

I believe this is a double definition.

'in excellent health' is the first definition.
(very well can mean healthy)

'all right' is the second definition.
(synonyms)

(Other definitions for very well that I've seen before include "Outstandingly" , "Agreed" , "okay" , "Phrase indicating compliance or assent" , "Probably" .)

I've seen this clue in The Guardian, The Globe and Mail and The Times.
