In two weeks I have a 6 hour layover in Newark before flying to Europe and wanted to know where people might recommend doing a bodyweight workout, or ideally some type of more private room in a lounge where I could set up my TRX, but I'm not counting on being able to do that

I'll be coming in to Terminal C through United and then transferring to Terminal B for my flight with TAP Portugal. I have prioritypass in terms of which lounges I have access to.
