Dumbells application

Hello everyone,

I was woundering if someone is actualy working on creating a dumbell app?

Here is how I would see it:

First of all a user would create his avatar, an avatar that looks like those images of body without skin, showing only muscle and maybe nerves. In the virtual gym the user would see his avatar in a hudge miror and he would see his moves handleing those dumbells with precision. Captors would show him to correct his position and his way to hold and move thise dumbells if necessary. While moving, he would see in different colors those muscles working. The app would suggest programs to workout and allow him to do his own programs and to share them.

I think some app like that would get great success.

Thanks
