Okay slave, it's almost time to get started. Have you ever seen a rugby player kick a penalty goal or conversion? Or a gridiron player attempt a field goal? Hell, even a soccer player taking a penalty kick is comparable enough to what you're going to be doing.
The only preparation left is to tie a light weight to the other end of the rope. A full 1L bottle will suffice, or a shoe filled with coins and plugged with a sock - whatever you have available really. Though, as you might have guessed, you should try and find something that won't break bones if you kick it; something soft is preferable.
