Avoid picking up heavy objects during pregnancy and follow these tips for light-to-moderate lifting: Keep your back straight, bend at the knees, lift with your legs, keep the object close to your body, and avoid a twist and lift motion. If you must twist, turn your entire body and feet to face the new location, rather than swiveling at the waist. (Use the same techniques postpartum when picking up your baby and any of his gear.) Most important, remember to ask for help when you need it. If ever there was a time when people are happy to come to your rescue, it's now.
