In medicine and occupations concerned with physical fitness, the concept of good posture is referred to as "neutral spine". [7] In this context, proper posture or "neutral spine", is the proper alignment of the body between postural extremes. Deviations from neutral alignment are identified as excessive curvature or reduction in curvature.
The McKenzie method is a technique primarily used in physical therapy.It was developed in the late 1950s by New Zealand physiotherapist Robin McKenzie. [1] [2] [3] In 1981 he launched the concept which he called "Mechanical Diagnosis and Therapy (MDT)" – a system encompassing assessment, diagnosis and treatment for the spine and extremities.
The number of vertebrae in a region can vary but overall the number remains the same. In a human spinal column, there are normally 33 vertebrae. [3] The upper 24 pre-sacral vertebrae are articulating and separated from each other by intervertebral discs, and the lower nine are fused in adults, five in the sacrum and four in the coccyx, or tailbone.
The WFEs stand in some opposition to another type of back exercises, devised by Robin McKenzie and known as the "McKenzie extension exercises", which involve the opposite motion of extending the spine backwards. One review stated that "Perhaps no two methods of physical therapy treatment for low back pain are so contradictory in both theory and ...
Exercises that strengthen the back muscles include rows, pull-ups, and shoulder blade squeezes. Exercises like doorway stretches for the chest can help stretch out tension that contributes to rounded shoulders. Synergistically implementing muscle strengthening and stretching can effectively prevent the development of rounded shoulders. [47] [48]

However the name 'hyperextensions' is a misnomer, because hyperextension means a movement where extension is performed at any joint beyond its normal range of motion. [citation needed] Instead, what one is trying to achieve in the back extension exercise is only to extend the spine within its normal range and not beyond its normal range of ...
