Orange Theory Fitness Portland teased the opening of a new franchise in South Portland earlier this week, but we still don't know where.

Orange Theory uses heart rate monitors during high-impact workouts in groups and with personal trainers. They have over 600 locations in the US and currently there is only one location in Maine on Marginal Way in Portland, but the Portland location's Facebook page shared this last week:

It appears to be an artists concept of a new location in South Portland, but there has been no mention of where. When asked in the Facebook comments when and where it would open, the response was only "Q2 or Q3 2018."

We've tried to match up the artists rendering with existing buildings in Portland but haven't had any luck, nor could we find anything with the South Portland planning board about an Orange Theory opening. Maybe it will be opening in a shopping plaza or possibly the Maine Mall? I guess we'll have to wait and see.

Where do you think an Orange Theory Fitness should open up? Let us know in the comments on our Facebook page.
