NOTE: THIS IS A MORE ADVANCED EXERCISE.
Begin by lying extended over a therapy ball. We recommend the use of a 55cm ball as the smaller diameter creates more lordosis (curve) in the lumbar
spine. Cross your arm over your chest or use your hands to support your head in a neutral position with your elbows out to the sides. Your head and neck should not flex forward during the
performance of this exercise. To help with that, it is recommended you pick a spot on the ceiling above your eyes and maintain your gaize on this spot the entire
Slowly contract your abdominal muscles focusing on pulling your chest toward your pelvis. Once you reach a neutral position (essentially with your back almost flat), hold and then very, very slowly return to the starting position. Repeat until you feel fatigue or a burning sensation in your abdominal muscles.
