Yep! I bought one when it was "fun, new and hot." Ha! And, as do most of these types of machines, it wound up folded up and under the bed.
Well, no more, I say! I dragged it out last week to do the semi annual deep vacuuming under the bed, and discovered that I can leave it mostly assembled, and slide it back under the bed in such a way that makes it really easy to slide it back out, do crunches, and slide under again. Yay!
As of tonight, I am officially up to 20 crunches per night. Go me, go me!
