Nice selection but needs more features

I purchased this since there seems to be a lack of decent stretching options that dont cost a lot. I actually do think they have a nice selection of stretches in here, but they do not have any instructions with the stretches. There are videos, but they only show the final position of the stretch with no guidelines or instructions of how to properly perform the stretch. If they added that, I think it would be a nice stand alone stretch app.
