Create a ninja warrior workout/obstacle course

Hi,
I am looking to create a class project for a group of teenagers aged 11 to 15 years to design their own workout exercise /obstacle course similar to the tv show ninja warriors. It has to be as fun and challenging as possible. *The kids will not be doing the exercises.

Can you design me a ninja warrior workout? (So I have one to show them)
- What would someone have to do?
- What fun names is it called? (E.g. Unstable bridge)
- How much time would you allow to do each part?
- What equipment would be needed?
- Any safety issues to think of?
- Best music to train with?
- Is it just a race against the clock or are there other ways to 'win'?
