Nik: The older a person gets, the faster the ass heads south. It’s not okay. You know what is okay? Circuit Works. I get so bored with gym workouts and kind of can’t stand classes, but this is the perfect place for my scattered mind. It’s an interval/circuit training workout that rotates through a series of stations combining aerobic and weight training exercises. The music is loud, the instructors motivating, and your mind is engaged because you’re quickly moving through the different stations.
