I'm a little stuck... Click here to teach me more about this clue!

'ernesto's exercises' is the definition.
I know nothing about this answer so I can't tell whether this works.

'tv channel series' is the wordplay.
I cannot quite understand how this works, but
'series' could be 'run' (a run or sequence of things) and 'run' is located in the answer.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?

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