Thanks, Jilliana and Vickie!
I checked out those 2 sites and the things look so cool. However I think my DH could rig up a pulley system with weights on one end and a bar handle on the other. It might be cheaper and take up less space.
All I really need is a monkeybar to hang from, really. If I just found one nearby (in the house) and really used it, I think I would get a great back workout. Until then I will keep doing rows of all kinds, pullovers, dead lifts, and supermans.
My house floor plan is open and only has doors at the bedrooms, and I work out far from there at 5 a.m., so I would need a freestanding one or something.
I have a high slanted beam ceiling so anything hanging from it could turn into a swing! and I would rather avoid that (I can just see myself inadvertently crashing my feet into the TV screen, LOL)
If I had experience using any of the overhead type lat equipment (resistance tubing, etc.) I would be more likely to want it. But I don't want to get another thing I will not use. So I will hold out for something very space saving, cheap, and simple.
