Safe lifting relies on using leg muscles, keeping the spine neutral, and avoiding twisting. Lifting with your legs means you bend your knees, squat down to the load, and then straighten your legs to lift, keeping the back straight and the load close to the body. This uses the stronger muscles in the legs and hips, reduces stress on the spine, and helps maintain balance. The other options don’t fit this approach: bending at the waist and lifting with the back puts undue stress on the spine; twisting the torso introduces dangerous rotational forces; holding your breath increases internal pressure and risk during the lift. So the action that aligns with this technique is lifting with your legs.
