WRONG. 90º posture is UNBALANCED and causes a lot more problems than just lower back pain.

90ºPosture gives you:

-compressed internal organs which makes deep breathing difficult, reducing your energy and increasing your stress.

- slouching because the body tries to get back into balance.

-lower productivity

-and yes, back and neck pain!

* Compressed Internal Organs makes breathing difficult, which reduces energy.

*Stretched Muscles right here lead to lower back PAIN!
