There is greater stability with feet comfortably spread. Back: Use the sit-down position and keep back straight but not vertical. A straight back keeps the spine, back muscles and organs of the body in correct alignment. It minimizes the compression of the guts that can cause hernia.

Arms and elbows: The load should be drawn close and the arms and elbows tucked into the side of the body. When the arms are held away from the body, they lose much of their strength and power. Tucking the arms in also helps keep the body weight centred. Palm: Palm grip is very important in lifting.

Use the full palm since fingers alone have little power. The fingers and the hand should be extended around the object to be lifted. Chin: Tuck in the chin so your neck and head continue the straight back line and keep your spine straight and firm. Body weight: Position body so its weight is centred over the feet. This provides a more power line of thrust and ensures better balance. Start the lift with a thrust of the rear foot.
