This week it's not even a stretch. You've got it easy, it's an active rest. A contradiction in terms I hear you say - well, give it a try, your back will want to kiss you for it.

Undo a day's tension by spending 20 minutes every day in the 'active resting' position. Lie on your back on a carpeted floor, with your feet on the floor and knees bent pointing upwards towards the ceiling, to free up your lower back. Support your head on some books, so that your head isn't tilted back, but not so much that your chin is at your chest. This position will help release tension, particularly in the spine, and give immediate benefit.

Another option is to lie with your legs on a chair [as above]. However, unlike the picture, make sure you have a book or folded towel under your head.

These stretches are ideal to do when you get home from work, before you start to do all those evening chores.
