I have also used PT on the Net.com and even uploaded some of my own custom exercises. It was clunky enough and lacking enough of my own specialized exercises that I finally just made my own library and use Word, then convert to PDF to send to my clients. They are able to view on ipad or smartphone, so it works well for them. Very labor intensive for me, but at least I was able to send pictures and descriptions of EXACTLY what I wanted my clients to be doing instead of having to constantly tweak somebody elses stuff. I will also be interested to see what IDEA comes up with.
