How to stretch at your computer

Ever wonder why sitting at your computer hurts? Could be lots of things, from the ergonomics of the chair itself to the length of time you spend poring over your work.

But one thing is for sure — stretching will help. Here are some ideas:

1. Arms: Straighten an arm out in front of you at shoulder height. Make a fist and bend the arm down as though pouring something. Hold for 10 seconds. Repeat five times.

2. Back. Put one foot on the opposite knee. Lean forward slowly and hold for 10 seconds. Alternate sides and do five sets total.

3. Legs. Stand with feet shoulder-width apart and place your hands as if sliding them into back pants pockets. Slowly lean backward a little and hold for 10 seconds. Keep your chin tucked into your chest, then look at the ceiling and return. Do 10 reps.

4. Hands. Straighten an arm in front of you at shoulder height. With the other hand, bend the wrist back so fingers point to the ceiling. Pull back on the fingers gently. Hold ten seconds. Do five total reps, then repeat with the other hand.

5. Shoulders. Reach one arm up straight above your head, stretching out the fingers. Move your head down to your chest and then back. Switch arms.
