Over three quarters of the time most Americans are conscious is spent sitting down. Considering the typical person is awake sixteen hours, that actually means you’re asleep in a prone position less often than you are folded down into a chair. Medical research links prolonged sitting to a host of medical issues, including increased risk for diabetes, cardiovascular issues, and of course back pain. Wall sits are an exercise that puts you in a sitting position, but against a wall without a chair; to strengthen the muscles in your back and legs. This can help counter some of the risks of sitting.
