You start of by visitng a Uni of Body and Signing up for The Test of the Weight Lifter (or maybe Iron Man LC ).
On signing up you get told a region where you should search for the appropriate weighted stone to start your training. (Part of the test will be finding these stones). On clicking on any heavy stone you will be told one of 3 things:-
After x number of exercises using the stone you would get 1 point of strength and the following message when you try to pick up the stone again.
"You lift the stone but suddenly it feels alot lighter. Your arms feel stronger and you feel ready for your next challenge. Visit a University of the Human Body for details of where the next stone can be found."
Repeat until Strength 7 achieved then lightning!
Ok that's the basic bare bones of it BUT it needs to be a little harder I think so some ideas as to the kind of exercises that could be done and how that could be implemented would be great!
And yes stones will all have a set weight which will not change so it would be possible to compile a database of which stone is heavier than the other. But with only 7 stones each that's going to take a long while. It might be an interesting side of the test though.
To clarify eveyone's required weight of stone is different.
