TIP No. 3. Get the audience to take an immediate action.

The point of all public speaking is to convince the audience to make a decision, which means convincing them to move (conceptually) from wherever they are now to wherever you'd like them to be.

Cuddy starts by getting the audience to move physically, thereby creating the momentum for the conceptual move she intends them to make. This is a more creative take on the "show of hands" opening that less-talented speakers use.

TIP No. 4. Create a sense of suspense.

In her first few sentences, Cuddy also promises the audience they'll be learning something important later in the presentation. This causes the audience to pay attention lest they miss the promised nugget of wisdom.

Note how cleverly Cuddy intermingles Tips 4 and 5! The suspenseful promise lends additional meaning to the movement, while the movement helps "lock in" the importance of the promise.
