I've done the Advanced Step Challenge twice and have really enjoyed it (plan to do it tomorrow morning). I thought it was as challenging as Cathe, but different. The combos are short and just as you get used to one, she starts the next. Some may not like this, but I think this will really stop boredom from long term use. I love Cathe and I love Christy and those are the only two I use for step (I really prefer intense workouts). I do not think Amy's choreography is as complex as Christy but it is harder than Cathe's choreography (but that may just be because I am so used to Cathe). I thought her cueing was okay, but not as good as Cathe. She seems to tell you what to do just as you are supposed to do it, not the step prior. But, I noticed on my second time through, this wasn't a problem for me. I "got" this workout much faster than I got my first Christy workout. I can usually get Cathe the first time through. I did not think the workout was as "fun" as Christy. But I still really, really liked it.
I enjoyed her choreography. Many fun moves that were intense. Lots of stuff I haven't seen before. She intermixes complicated steps (like the crazy shuffle) with easy steps. That way, if you are still learning and haven't quite gotten the harder stuff, it's easy to figure out where you are and try it again the next time through.
I have been having issues with my achilles but this workout did not seem to bother me the way that Cathe sometimes does. Not sure if it's because it doesn't have as much jumping or what?
I highly recommend watching the section where she teaches the more complicated moves. I got this down before I did the workout for the first time.
I plan to keep this one and do it often. I will continue to buy her workouts in the future.
Whooping didn't bother me. I didn't even notice.
Not sure if this will mean anything to you, but I also recently purchased Ready, Step, Go and did not like it. I stopped it midway through and haven't done it again. It was just bland to me. Not sure why, could have been my mood. Although Amy's Advanced Step was not as "fun" as Christy, I did not find it "bland" either.
Feel free to email me if you have other questions. There's a lot of differing opinions out there. I know it's confusing and hard to make a decision.
