The SOS strap is unique as it has loops that hold your hands or feet in a desired position. You can use a yoga strap or band - it just may not have the exact same effect. Let me know how it goes.
Rachel we tested all three formats and can't see a problem, though admittedly it took longer than normal to load the class. Would you mind checking it again at your convenience? Make sure to close programs you don't need open and if you haven't restarted your computer in a while that is a good idea too. Thanks.
Kristi, The first time I tried this class I had no problem viewing this class. But this morning I wanted to retake this class because it was so good. And it wouldn't reload.
