Struggles to exercise extraordinary gifts, getting out of breath (6)
I believe the answer is:
fights
'struggles' is the definition.
(fight is a kind of struggle)
'extraordinary gifts getting out of breath' is the wordplay.
'extraordinary' indicates an anagram.
'getting out of' is an insertion indicator (to be outside something can mean to be around it).
'breath' becomes 'h' (I am not sure about this - if you are sure you should believe this answer much more).
'gifts' is an anagram of 'figts'.
'figts' placed around 'h' is 'FIGHTS'.
'to exercise' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for fights that I've seen before include "Scraps" , "Brawls" , "Conflicts" , "'Combats, battles (6)'" , "Boxing matches" .)
