1. They start by learning how to track animals so well that they can identify an individual from among a herd's tracks. (in other words, crazy, crazy good)
2. Long before the hunt, they bury water in ostrich eggs under strategic trees
3. They then throw a rock at some antelope which then flee in panic.
4. Track the juciest individual (this is key - you have to chase the same animal for days on end)
5. Repeat rock throwing, individual tracking, and strategic water drinking until the animal's muscles stop working. Then you get it with an arrow.
