Just for start, to go easy on you, give me 20 hits with the ruler.
After a rest of 15 seconds, do it again.
After you finished all of the hits I want you to use the second shoelace
and tie your first one to the belt. You should be in a position in which you
can't stand.
After that you can press continue.
By the way, if I didn't mention it before, it was 20 hits to each ball!!!
If you didn't do it that way start this page again and then press
