I have the intensity series (and some hardcore on the way, yay!) and a very small home. My 'gym' is my living room. The only time I feel like I need more room is when she does double grapevines. In that event I just take extra tiny steps LOL. It does take a little effort every morning to move a couple things and pull the weights out, but it's amazing how quickly that gets done when you do it every day! With a little creativity you'd be amazed at how little room you do need. HTH.
