Here are some more great exercises for confined spaces to help your body from getting too stiff:
For the Neck:
1) Sit up tall in your seat.
Tilt your head slightly to one side. (You want to feel a gentle stretch not a strain.)
Focus on tilting your ear to the shoulder, not your cheek to the shoulder.
Hold for a count of 10.
Repeat other side.
2) Turn your head to one Side
Tip your chin as if you were looking at your shoulder. (Again, you want to feel a gentle stretch not a strain.)
Hold for a count of 10.
Repeat other side.
Check back tomorrow for more exercises you can take with you whenever you travel.
This is also good for those of us who have to sit for long periods of time at a computer. Getting up to stretch all over is great, but sometimes you need to focus in on the head/neck area, too.
