In my free time I've been making a program to just keep track of my workouts. At the point I've gotten to I've realized that I could expand it a bit and it'd be useful to many that want to keep track of their workouts.

I have some idea of where I want to go with this but nothing set in stone. I won't explain them (in this first post) so I don't set anyones mind in a certain direction. Really, I am curious of two things.

-What would you want to be able to achieve\see with it?
-Would you pay for a program like this? How much?

I have a few ideas but I decided to ask this while I am still on the "bottom" floor of making this so if there are great ideas I can implement them easier\better.

Thanks for any input!
