I still use older tapes. This Friday, for example, I will do Cather's very first tape, "Step N Motion" (1990). Next year marks its 20th aniverary! I have used it off and on, and the tape is still in very good condition. Cathe's brashness and good sense of humour were in play way back then. And though this VHS tape made waves for its athleticism and advanced difficulty at the time, the step moves are very doable. But at my older age I have to modify some of the plyometric jumps and weights.
