I'm Jeremy Shore for LIVESTRONG.COM, here to talk about office stretching techniques. Sitting for long periods of time can cause key muscles in the body to become tight, and ultimately, weak. Take every chance you can to get up and walk around the office. But also, try these great stretches to counteract the effects of sitting for long periods of time. First, we'll stretch the hip flexors and upper quads. Sit on the edge of your chair. Put one leg back. Sit nice and tall. Draw the abs in. Let's try to straighten that back knee ever so slightly, until you feel a good stretch down the front of the upper leg. Hold that for 20 to 30 seconds, breathing deeply through the nose, and then switch sides. Next, target the lats and the triceps by sitting up tall in your chair. Take one arm, bring it behind your head. Take the opposite arm and grab the elbow, and slightly pull across the body till you feel a good stretch in the back side of the arm, and down the side of the body. Breathe deeply. Hold for 20 to 30 seconds and switch sides. And finally, target the tight neck muscles by sitting up tall. You can hold on to the side of your chair. Drop your ear towards the opposite shoulder, until you feel a light stretch in the neck. You can add a little bit more to the stretch by placing the opposite hand and slightly pulling. Breathe deeply. Hold for 20 to 30 seconds and switch sides. This has been office stretching techniques. I'm Jeremy Shore for LIVESTRONG.COM.
