Well, after all of the talk about these straps, I did some research and bought some! I ended up with the Lifeline Jungle Xt straps, basically half the price of TRX. I've used them a couple of times now, and can honestly say that there isn't a body part that you can't train if you choose to. Good quality straps, and made in the USA!

I'll offer some classes in the shop along with trainer rides this winter and probably at a small hospital where I work part time as well.
