STARTING POSITION:
Stand straight with your feet shoulder width apart. Put a bar on the traps and grab it firmly with your hands.
MOVEMENT:
Slowly move your belly to the right and move the arms to the left until you feel the stretch in your oblique and back muscles while you exhale. Return to the starting position with a smooth movement and repeat to the other side.
TIPS: You should feel the stretch of the muscles but not pain.
