The Centra is a great place, with great hours, even in summer, for before and after work excercise. I believe hours, for summer, are M-F 5:30am-8:30pm, with weekend hours opening a little later say around 8am. There is a nice variety of classes (aerobics, yoga, etc.) available also that are included in membership. Great environment to exercise in, not to mention the 6 new flat panel televisions to gaze at while on the cardio equipment.
