If you're like most people, you've probably skipped workouts because you just didn't have the energy to do them. You plan to exercise in the morning, but darn it, you didn't sleep that well and you need an extra hour of shut-eye. Or you look forward to a post-work stress blaster, but after a rough day at the office, you can barely face the commute home, much less working up a sweat on the elliptical. The solution?

Tailor your workout to your energy level. Just mix and match these routines--two cardio and two strength--depending on how you feel (raring to go or tapped out). You'll slim down in five weeks, burn more calories and fat, and never miss another workout again.
