When we moved, the only (VHF) tape I brought with me was the Kathy Smith "Fat Burning Workout". I continue to use that. When I stumbled upon tapes for weights, I knew I had to order them, and I am not disappointed. Her programs are east to follow, and she is asy to understand. I'm 73 and need to keep muscle strength and this fits the bill. Will continue to look for more tape from Kathy.
