Well you get a whisk, and hold it in the hand you write with/are strongest with. Then pick up the bowl, with the mixture to be whisked in, with your other hand at waist height right in front of your stomach. Then you put the whisk in and move it in circular movements through the mixture, very fact, until it is completely mixed. Hope this helps (:
