Anyone else use these tapes? I purchased them at Sam's for $17.99. That included 3 tapes and the balls you fill with water to make hand weights. I've only done the 1 Mile and the 2 Mile, but I'm going to try the 3 Mile next week. I get bored with listening to her, so I turn off her sound and put on my own music. What she does isn't complicated so I don't really need to hear.
