Just fyi --

Don't buy resistance bands that have a braided covering. I have a Nike set that's covered in braided nylon. They'll stretch to a certain point, then the braid "locks" and you can't stretch them any further. This makes using a loop completely ineffective since you'll probably run out of travel before you've finished the exercise's range of motion (such as only managing curls instead of an overhead press).

Here's the one I got. I don't even know where it is now; I might've thrown it away.
