I subbed Low Max for 4ds double cardio premix...I was just in a mood to be funky with the hip hop groove of that one, but now after reading about everyone's LM experience makes me wish I did it.
Cathy, any chance the back DOMS are influenced from your peri-menopausal symptoms? I find sometimes that my back feels, meh, and then sure enough a couple days later I get my visitor. With the sleep deprivation your hormones must be in flux. I feel for ya, I'm starting the hot flashes and night sweats, no fun to get up in the middle of the night soaking wet to let the dog out and the house is freezing....brrrr.
