How Do You Perform a Trunk-Lift Exercise?

A trunk-lift exercise begins with the person lying on the floor with pillows under the hips and forehead. The head and shoulders are lifted straight up while the shoulder blades are pulled back gently. This position is held for a count of two, and then the trunk is lowered.

This exercise, which strengthens the back extensor muscles, is repeated three to five times when the person begins the workout. The goal is 15 to 20 extensions at a time performed once or twice daily, according to physiotherapist Vivian Grisogono. During the exercise, the back is not arched, so the head, neck and back are all in line. The person continues to breathe throughout the exercise, exhaling when lifting and inhaling when lowering.
