Anterior pelvic tilt (APT) is poor posture due to the combination of hyperactivated and inactivated muscles. Hyperactive muscles shorten due to constant contraction and the opposing muscles lengthen due to inactivity. This combination then leads to the pelvis to rotate in an anterior (forward) direction. Hyperactive muscles are overactive muscles, which aren't letting their reciprocal muscle innervate properly. In APT, the hyperactive muscles include the Hip Flexors—which consists of our Rectus Femoris, Tensor Fasciae Latae (TFL), Psoas Major. Another hyperactive area is the Quadricep Femoris—which consists of the Rectus Femoris, VMO, VLO, and VI. The final area tends to be our spinal erectors such as the lumbar, thoracic, and cervical spine and the muscles that run along the spine. All of these muscles being hyperactive pull the pelvis forward. These hyperactive muscles mean that somewhere there are weakened, inactive muscles. This is where reciprocal inhibition comes in. The weak, or deactivated, areas consist of the Gluteal Muscles. Also, there could be involvement of the Hamstrings, a group of muscles and their tendons at the rear of the upper leg and the abdominals: these muscles will rotate your pelvis posteriorly. Correcting Anterior Pelvic Tilt is about correcting our muscular imbalances. I will cover how to correct Anterior Pelvic Tilt, specifying how to strengthen and activate the weak, inactive muscle groups while loosening the hyperactive muscle groups.
