What is a posterior pelvic tilt and in which general type of exercise would you cue it?

• A. Tilt tailbone toward the floor; useful in abdominal or spinal articulation exercises to flatten the lumbar curve.
• B. Tilt pelvis forward; only for leg work.
• C. Tilt pelvis laterally; used in side-lying.
• D. Tilt pelvis backward; not used in reformer work.

Answer: (A)

Posterior pelvic tilt means tilting the tailbone toward the floor, which shortens and flattens the lumbar curve. This helps stabilize the spine and allows the abdomen to engage more effectively. Cueing this tilt during abdominal or spinal articulation exercises keeps the pelvis from tilting forward or arching the lower back, so the movement comes from the torso with reduced risk of back strain. In reformer work, you’ll often use this cue when the goal is to control the spine and pelvis during flexion or articulation moves, ensuring safe, precise core engagement. Tilting the pelvis forward would be an anterior tilt, lateral tilts occur to the side, and the idea that posterior tilt isn’t used in reformer work isn’t accurate.
