Very Beginner Tennis...Groups? In NYC

Basically the title, sorry if this is a silly question, I know so little about sports beyond bare-bones fitness. I've been wanting to get into tennis (or any sport, really- I'm a very solitary runner) for a while now, but I've been having a hard time finding group classes for complete beginner adults in NYC. I was wondering if anyone knew of any regular-ish tennis lessons with a smaller group in NY, or if there was a similar sport with a group-lesson format for adults? I've looked everywhere but have only turned up private coaching or groups for advanced/intermed. players.

Thanks in advance!
