The postural model does not hold up to rigorous research. There is no ideal position for standing, sitting, or squatting. No reserach to date has identified a level of stress that is too much for our bodies to handle, particularly regarding sitting or standing.

Research shows lifting with a rounded back is not only safe but often ideal. Furthermore, it is impossible to maintain a neutral lumbar spine past roughly 20 degrees of hip flexion.

We need to encourage people to move more, not less. The message of an "ideal" posture or movement perpetuates a fear of activity when there is no research to support that posture predicts future pain or injury.
