Mobility

The drill creates a small amount of expansion through the upper back. The combined hip shift, spinal rotation, arm reach, and breathing are intended to improve mobility across the frontal and transverse planes. The drill can help loosen multiple areas of the body at the same time. Relaxing and opening the posterior hip and ribcage areas can support frontal-plane and transverse-plane mobility of the thorax and hips. The drill may assist shoulder internal rotation on the elevated-foot side. Mobility is framed as broader than flexibility and includes moving through life with ease and less pain. Normal human range of motion is presented as broadly consistent, while allowing for individual exceptions. The drill emphasizes segmental spinal movement. Modern sedentary environments reduce natural movement variety and can narrow physical capacity. Usable range of motion gives the body more options for solving movement problems and tolerating demands. The lower body should curl upward gradually one segment at a time. Improving upper back mobility is a stated goal of the doorway drill. The activity works on mobility as well as pressing skills.
