I owned this VHS cassette many years ago but it got lost in a move to a new residence. I reordered it through Amazon and like the simplistic lessons it teaches. There are 3 different levels to "master" but you can simply skip around once you've done them all a few times. I like the fact that the warm ups and workouts are fairly short. I also like the instructor's philosophy of holding a hand on the isolated muscle that you are working which helps connect the mind with the body. Only negative is I wished it was now updated on DVD as my old VHS machine is near obsolete.
