Intensity series is all I have right now, so ME is my only total body weight vid. I love it, but it is a killer. I have learned to love those butt thingies (even though I hate them-;-) ) because I've never had anything that I could FEEL working that area so well right at the juncture of butt and hamstring. At my age (49) that's right where I need a 'pick me up'.
But, yes, it is hard. One of the reasons I so often work out at 4:30 am is so no one sees or hears me crying . :+
