Complement your cardio (30 minutes of walking a day, remember!) by adding in 3 sets of 100 “jacks” throughout the day.
It only takes 2 minutes to complete each set, and you’ll burn a total of 60 additional calories a day. Every little bit helps! Squeeze in a set -- traditional high-impact JJs, or modified low-impact JJs -- before showering, while your computer is booting up, during a TV commercial break, or while dinner is cooking. Such an easy way to get your heart pumping and rev your metabolism!
