I too, would simply buy the TRX. I would trust my building of this, but also think there are features that would be hard to duplicate. From videos I've watched, it seems that there is a bit of suspension in the straps... is that correct for anyone that has used one?

For those of you that might want to build your own, I do know there is a link on Facebook that shows you how. I wish I could offer the link, but I can't.

Thanks for all of the great opinions!!
