When I played basketball in high school, my least favourite part of practise was running wind sprints. Essentially, I ran the length of the basketball court as hard as I could as many times as I could before collapsing like a Jenga tower in a pool of sweat.
Wind sprints were great for getting into game shape; however, they had little to do with actually playing basketball.
Preparing for your next meeting is running wind sprints. Rembember, though running wind sprints during your meeting won't help you win and may actually hurt your cause.
In polite terms this is called "info dumping." Blowing through your prepared statement while your meeting participants sit stunned, waiting for you to take a breath and say something that they actually care about.
To win show up in the best shape, but don't spend your time running wind sprints, play your whole game.
