Change Your Body -- No Gym Required

Rise and shine. If you feel out of sorts when you're away from home, set aside 15 minutes in the morning to stretch, breathe deeply or do other wake-up exercises to get the day started on the right foot.

Get strong whenever you can. On the plane, push your heels into the floor and contract your glutes for in-your-seat firming.

Use what you've got. Create your own version of a hotel workout. Use a large phone book to do step-ups and calf raises, a desk chair to do dips, squats and lunges on the bed (which also helps your balance), biceps curls and rows with water bottles, and running the stairs to add cardio.
