I figured this would get some views. Im not doing it but my wife has some new hip movement I kinda enjoy. Anyone have a female in your life doing this stuff. Its taught her some new sex moves but I can't tell her body is doing much but I told her once a week isn't going to. Anyone notice a difference with your significant other doing this? Seems like it hits mostly core but I have not, no lie, every watched them do any of it.
