While normal rappel is used for moving from a high position to a lower position (e.g. from bridge to valley bottom) in a swift but orderly manner, Swedish rappel is a faster and more aggressive method used in order to achieve the same result.

In order to perform a Swedish rappel, one must:
1. Acquire a length of rope (e.g. two feet)
2. Move to place where Swedish rappel is to be performed
3. Hold one end of rope in hand, let the other end dangle free.
4. Jump
