Prevent Back Pain

Needless to say I rebelled and am round-shouldered to this day.

It turns out my school was wrong. New research shows that sitting in an upright 90-degree position places more strain on our back than sitting slightly reclined at 135-degrees.

"Everybody knows that if you sit for long periods you have back pain," Dr Waseem Amir Bashir, a radiologist from the University of Alberta Hospital in Canada told Reuters Health in November, 2006.

Back pain is the most common cause of work-related disability in the United States.

• a slouching position in which the body is hunched forward, as over a keyboard;

 
• an upright straight-back position with legs at 90-degrees and knees and hips at the same level;

 
• a "relaxed" 135-degree tilt position.

"We found this 135-degrees to be the ideal sitting position because it's similar to a neutral relaxed lying down position."

As expected, "the bending forward or slouching position is the worst sitting position for your back.".

This also gets your lymph circulating, especially good for the tiny capillaries behind your eyes. You know that finger joints and eyes suffer most at the hands of a computer. Look out to the horizon and all around as you jump.

Of course lymphasizing (another word for rebounding) quickly removes toxins from cells and brings fresh nutrients in. Our lymph is the fluid surrounding every single cell.

By fisting and flexing your fingers while you jump, and twirling your wrists around, you also relieve the RSI (repetitive stress injury) from keyboard and mouse.
