Orangetheory Fitness makes its debut at Park Potomac next week, just across the street from MoCo’s Founding Farmers. This is the second Montgomery County location for the Florida-based fitness chain, which offers heart rate-monitored group workouts with intervals of cardio and strength training. Grand opening party is Dec. 8th from 6 to 8 p.m — with orange crushes to drink, of course. Click here for more.
