ABSTRACT:
A new and improved information storage and display apparatus includes an outer information-bearing member and an inner information-bearing member. The outer information-bearing member and the inner information-bearing member display information relating to exercise routines. The outer information-bearing member includes an array of windows and window-associated informational data. The inner information-beating member includes an array of information fields which contain information data. The information data in the respective information fields are arranged in respective linear stacks. The array of information fields and the linear stacks of information data are arranged such that the information data in the respective information fields are registrable with the array of windows in the outer information-bearing member. In addition, the arrangement of information fields and the linear stacks of information data provide that all corresponding information data in all information fields are incremented in all windows simultaneously when one information data in one information field on the inner information-bearing member is incremented with respect to one window in the outer information-bearing member.
