Your body hates boredom. Give it the same workout every week, and it will stop delivering results. These workouts pack in the variety you need. Plus, they combine upper- and lower-body moves to get you out of the gym fast (check it out — you only need to do 5 resistance moves per gym session!).

The rules:
Cardio must be done after weights. And you must take at least one full day off every week, since your body builds strength while you're resting, not while you're working out.
