With its modern interior and exterior, indoor track and spacious confines, the new YMCA in the heart of downtown Houston breathed new life into fitness in our city. Hell, sometimes we go just to gawk at the view of the skyline from the treadmills, and before we know it three, er, ten miles have passed us by. Replacing the historic building less than two blocks away, this YMCA opened up just last fall, with upgraded equipment, locker rooms and family areas. There's also an indoor playground area that makes even adults jealous. Everything is new and improved, from the saunas and steam rooms to the basketball courts, which are always teeming with the sounds of vigorous games of roundball. The old location isn't all forgotten, with the neon "Y" from that building displayed prominently in the free-weight area of the gym.
