Sorry, Anna, I don't have a computer at home and just now noticed your message.
Yes, I do the step portion of 10-10-10 on an 8-inch step with high impact. I pretty well do everything high impact -- otherwise I get bored and lethargic and, for some reason, feel unbalanced and heavy as an elephant when I do low impact. I like my workouts to be fast and furious!
