Silly son's 50-50 after exercises, having a funny turn (5,5)

Ross

I believe the answer is:

dizzy spell

'a funny turn' is the definition.

'silly son's 50-50 after exercises' is the wordplay.
'silly' becomes 'dizzy' ('dizzy' can be a synonym of 'silly').
'50 50 after exercises' becomes 'pell' (I can't justify this - if you can you should give a lot more credence to this answer).
'dizzy'+'s'+'pell'='DIZZY SPELL'

'having' acts as a link.

I've seen this clue in The Guardian.
