I trained in a way to be more fastidious (8)

I believe the answer is:

daintier

'be more fastidious' is the definition.
('dainty' can be similar in meaning to 'fastidious')

'i trained in a way' is the wordplay.
'in a way' is an anagram indicator.
'i'+'trained'='itrained'
'itrained' is an anagram of 'DAINTIER'.

'to' is the link.

I've seen this clue in the Sydney Morning Herald.
