Another quick reminder of proper posture. It is best if you can bend your knees and keep your back straight when you lift. This is not always possible, soeven if you need to bend at the hips to lift, here is a tip for decreasing strain on your back:
It’s important to maintain lumbar lordosis and pelvic anteversion (in the left-hand graphic above, the arrow depicts the proper counterclockwise rotation of pelvis) when bending or lifting. Even if you bend forward at the hip, as long as you bend thru the hips and maintain at least a flat spine or slight lumbar lordosis, this protects the back. Note that you will need to have limber hamstrings to be able to bend this way. Alternatively, you can squat when bending or lifting; however, be careful to continue to maintain the lumbar lordosis and not try to lift too much on one side (i.e., it’s best to lift equal amounts in both hand to balance the forces on the spine). If you allow the “C” curve to develop while bending (whether squatting or not), it markedly increases the stress on your spine.
