Modify a name for physical training (5)

I believe the answer is:

adapt

'modify' is the definition.
(thesaurus)

'a name for physical training' is the wordplay.
'a name' becomes 'ada' (**).
'for' says to put letters next to each other.
'physical training' becomes 'pt'.
'ada'+'pt'='ADAPT'

(Other definitions for adapt that I've seen before include "match" , "Alter, amend" , "Make fit" , "Fashion" , "Convert to another use or situation" .)

I've seen this clue in the Evening Standard.
