I started to go to a gym regularly in May. Now I continue this habit.
What should I say to express this idea?
I've been to a gym regularly since May.
or
I've gone to a gym regularly since May.
What do you think? Why?
I think "been to" is correct, because "gone to" means you haven't returned.
"Been to a gym regularly" refers to go and come back, go and come back, go and come back.
