Diane: I can't get the collage preview to work - I've tried for two days but it keeps kicking me off the Internet. Is there anyone out there who can answer my question as to whether the HSC uses the high steps for aerobics or is it used for things like lunges and squats and dips? Please, I don't want to buy it to find out it's used for step aerobics because I won't ever do that on a high step again. Thanks.
