Hold plate behind neck or on chest with both hands or use no weight. Execution: Flex waist to raise upper torso. Return to original position and repeat. Comments: Weight can be held behind neck. Certain individuals may need to keep their neck in neutral position with space between their chin and sternum. Exercise can be performedwithout added weightuntil more resistance is needed. Movement can be made easier by positioning hips low on ball. In contrast, exercise can be made more challenging by positioning ball lower on back and hips higher. Some individuals may experience low back discomfort if hips are not bent, so they must use smallerball sizeor lower their hip position on ball.
