Useful stretch to do at your computer

It's generally recommended to take a 5 min break every hour or so, if you work for long periods at your computer.
Things to do during those 5 minute beaks:
1. Walk around your office, or room if you're at home.
2. Look at far away objects or at the wall across the room, to stretch your eye muscles.
3. Do simple wrist rotation exercises.
4. Bend and touch your toes, or as far as you can reach.
a5. Try this relaxing and loosening stretch for your arms which spend long hours in an awkward typing position. Your arms will thank you for it:
Stretch exercise 1:
Hold one arm in front of you so that it is parallel to the floor. Keeping your arm parallel to the floor, point your fingers upwards so that your palm faces forwards similar to a HALT gesture. Use your other arm to push your fingertips back towards you till you feel the stretch in the underside of your lower arm, between the wrist and elbow. Hold for 15 seconds.
Repeat with the other arm.
Stretch exercise 2:
Hold arm parallel to the floor, again. But this time rotate your arm so that your palm faces towards the ceiling.
Use your other arm to push your fingers down towards the floor till you feel the stretch in the underside of your arm between elbow and wrist. Hold for 15 seconds.
Repeat with other arm.
