I've come up with two words, but not sure if they are the most common collocations in this case.
laborious method
arduous method
Both of them sound rather formal to me. So, I would like to ask, how to make them sound more colloquial without changing the meaning here?
You can say a demanding or challenging method, which is less formal than arduous and laborious.
A more neutral adjective would be difficult.
If you want to be even more colloquial you could say a tough method.
