Explanation:

Proper lifting procedures involve bending at the knees to use the leg muscles for lifting, keeping the back straight to prevent injury, and lifting with the legs. Bending at the waist and lifting with the back can cause back strain. Keeping arms and legs straight is not part of proper lifting as it doesn't engage the right muscle groups.
