Versatile Straps

These NRS straps look like the perfect thing for improvising some excellent fitness equipment. Buy a couple swing hangers and screw them into your basement joists. Then get a pair of 20-foot straps and something like vinyl tubing, PVC, or pipe nipples to use as handles (take care about sharp edges rubbing the straps). Thread a handle onto each strap and then make each strap into a loop. Hang loop from the swing hangers. Instant cheap-o gymnastic rings (here's the real deal). Since you can easily adjust the length of the loops with the cam buckles, you have an excellent unstable platform for dips, pushups, flys, "roll-outs", etc. You can also monkey with the handle configuration. I imagine you could make nice handles for these extreme renegade rows with a couple pipe T fittings and three pipe nipples. Something like this:

The looped straps would also be perfect for a variety of isometric exercises, I bet. Cheap, too. Might want to get a few so you don't have to thread different handles for different exercises. Not sure about shipping cost, and I have no experience with this vendor.
