Research has advanced our understanding of core stability, including the need for different stimulus to optimally develop strength versus stability. This workshop will provide exercises designed to progress to allow high intensity overload that has been shown to be ideal for fostering core strength and related physiological benefits. It will also incorporate large exercise balls and rotator discs into classic and novel reformer exercises for development of the proprioceptive aspects of multi-planar core stability. A particular emphasis will be placed on the use of rotation because of its common association with functional movement and injury.
