In the deadlift, which fault corresponds to loss of midline stabilization (flexion)?

• A. Weight shifting to the toes
• B. Loss of midline stabilization: flexion
• C. Bar moving around the knees during descent
• D. Bar drifts away from the body

Answer: (B)

In a deadlift, keeping midline stabilization means bracing the core and maintaining a neutral spine so the trunk stays rigid while you lift. When that stabilization is lost and the spine flexes, the torso rounds forward and the back loses its neutral position. This flexion is a clear fault because it compromises the ability to transfer force efficiently from the ground through the hips and spine, increasing stress on the lumbar region and the risk of injury. That’s why loss of midline stabilization: flexion is the best descriptor for this fault. Other faults describe different issues—shifting weight to the toes changes balance and knee/hip loading, the bar moving around the knees signals inconsistent bar path on descent, and the bar drifting away from the body points to poor upper-back/lats control—not the midline flexion itself.
