I did this workout today even though I haven't built up my core as much as I would like before attempting it! This one is TOUGH, but it is so practical for the things we do in our daily lives. There is a lot of variety and I appreciate that Cindy doesn't perform a move many times. It is done a few times and then on to the next move. Great cuing, innovative and some of the moves are deceptively simple so look out! Cindy is an amazing athlete and definitely an instructor to aspire to. This is definitely a new way to workout!
