From the author: "A daily exercise plan! Do these exercises throughout the day (and add in your own) to get into the habit of daily fitness. Note that I said “throughout the day.” These aren’t meant to be completed all at once, though you could if you’re that fit. But feel free to do only 10 or 20 jumping jacks at a time. Just keep track of them and try to hit the goal before you go to bed."
