Using the foundational exercises on the Arm Chair (aka Baby Chair) at Marbella Pilates we use the chair to buildsstability in the body by providing an anchor to lengthen the spine against—the feedback the back of the chair provides is pure Pilates genius. As the exercises build, the back of the chair can move with the body requiring the spine to lengthen even more. Kathi provides a spotter to assist the movement if the student is not able to shift it yet. Three different versions of each exercise are shown simultaneously so you can see how each serves a different purpose, for instance holding the hand in a fist builds strength and control, while lengthening the fingers provides a stretch through the arm. The Arm Chair teaches the spine to lengthen while in a sitting position, which is particularly important in today’s society because learning to sit with proper posture is key to health!
