A device for recording a series of exercises to be followed over a period of days and for indicating the order in which the exercises are to be performed on a given day. When the exercises are recorded in pencil, they may be erased and rewritten when the exercise regimen is changed by the exerciser. The device includes three flat, circular plates that are rotatable independently of one another about a common pivot point. A plurality of radially extending lines are disposed on a base plate and one exercise is written on each line. Exercises to be performed in one day are grouped together on contiguous radial lines. An intermediate plate has a window formed in it that exposes to view a group of the radial lines when the window is in registration with the group, and a pointer plate includes a pointer that points at an exercise written on a particular line of the group that is exposed to view. The pointer is indexed to the next contiguous line after the performance of each exercise and the intermediate plate is indexed to expose the next group of exercises at a time selected by the exerciser.
