If you spend long hours working at your computer, with only an occasional jaunt to the lunch room, you might benefit from Twittercize. Ron Doyle is a Denver-based freelance writer who posts short exercises in Twitter, and they’re designed for you to do in a minute or so at your desk.

During the workday, he posts about one tip per hour. For example,

Dilberts: Sit upright, cross arms at chest, contract stomach muscles. Bow forward like you're banging your head on your desk! 30 times slow!

or

Hulk Hogans: Elbows up, hands at your heart, pull back like Hulk ripping a yellow tank top! Squeeze those shoulder blades 30 times!

Twittercize is free and much easier than getting out to the gym for a workout, although there’s a disclaimer that you should consult your physician before starting any exercise program.

You can follow Ron in Twitter at twitter.com/twittercize. For more detail on the exercises, you can read the Twittercize blog.
