Beat current that's good for women (4)

Ross

I believe the answer is:

flog

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

'beat' is the definition.
(I know that flog is a type of beat)

'current that's good for women' is the wordplay.
I cannot quite see how this works, but
'good' could be 'g' (abbreviation) and 'g' is present in the answer.
The remaining letters 'flo' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for flog that I've seen before include "Exchange for money" , "Hit - sell" , "Whip severely" , "-- Hitler" , "Swing a cat, perhaps" .)

I've seen this clue in The Telegraph.
