Which syndrome is characterized by tightness in the hip flexors, latissimus dorsi, and lower back, with lengthened abdominals and gluteal muscles?

• A. Upper Cross Syndrome
• B. Lower Cross Syndrome
• C. Kyphosis
• D. Scoliosis

Answer: (B)

The pattern being tested is a common cross-imbalance where the front of the body is overactive and the back is underactive. Specifically, hip flexors and the lumbar spine tend to be tight, while the abdominals and glutes are weakened and lengthened. This combination pulls the pelvis into an anterior tilt, increases the lower back curve, and shifts load through the spine, creating the postural and movement issues typical of this syndrome. The description—tight hip flexors, tight lower back (and even the latissimus dorsi as part of the posterior chain), with lengthened abdominals and glutes—fits this lower-cross pattern well, because it highlights the opposing forces between the dominant front/core muscles and the weakened back/posterior muscles. Upper Cross Syndrome, by contrast, centers on tight chest and upper back muscles with weak neck flexors and lower traps, which is a different imbalance. Kyphosis and scoliosis refer to spinal curvatures rather than this specific muscular-length pattern.
