The Workout o' the Week is a 3-minute drill. Go through it 3 times, and you've still exercised less than 10 minutes!
20 sec pushups (from knees, eventually)
20 sec situps (by the end, you'll just be trying to get your shoulder blades off the ground)
20 sec shrugs
20 sec mountain climbers
20 seconds band curls
20 seconds jumping jacks to your heels (on the down stroke, touch your heels, not your thighs)
60 sec surfer pop-ups. Lie down on your stomach with your right hand forward and your left hand against your left hip. Pop up quickly into a standing position, and immediately lie back down. Switch hand positions after 30 seconds.
Now go...quickly! Before the zombies get here.
