Make sure the load is stable, balanced and light enough for you to safely lift. If it is not, get help or use a dolly or some other lift aid.
Find a route that is free of slip and trip hazards. Figure out where you will drop the load off, and plan rest stops along the way if necessary.
Keep your feet at least shoulder-width apart. A staggered stance, with one foot slightly behind the other, can help form a strong base of support.
Bend at your knees, not at your waist.
Grip the load firmly, using your whole hand, not just your fingers.
Flex your knees and hips, not your back, and avoid bending at the waist.
The closer the load is to your body, the less force it puts on your back. Carrying 10 pounds at arm’s length feels like lifting 100 pounds.
If you need to change direction, move your feet, taking small steps.
