Hi Conni,
PUB - all time fav. weight workout. It's effective and quick. I am not sure why Cathe doesn't make another one of these.
Today I did Meso 1 disc I don't know - back and triceps.
Do you have think Xtrain will be an updated version of CTX or 4DS - I don't use those much so I am really on the fence here.
Have a good day everyone.
