Principles of Back Mechanics
1. Be aware of your center of gravity (one hand’s breath below the naval and just in front of the sacrum). Let your arms be an extension of your center of gravity.
2. Bring any object you plan to carry or lift as close to your center of gravity as possible.
3. Instead of bending, consider a modified squatting technique: lower your center of gravity, as if “sticking your butt out” with flat back while lowering yourself to sit on a chair. Use your center of gravity, pivoting with hips or feet, to turn or move closer to where you want to go.
4. No twisting while reaching:
Consider “headlights” on pelvis and shoulders. No reaching outside of the field of all four lights pointing straight at the object involved.
5. No crossing your legs during sitting!
6. Keep feet in even depth of car well during driving.
