Which contraindicated exercise involves bending the spine forward with little back support?

• A. The plow
• B. Back bend
• C. Deep squat
• D. Unsupported forward flexing

Answer: (D)

Forward bending of the spine without stabilizing support stresses the lower back and relies on the spine to carry the load rather than the core and legs. This reduces spinal stability and can cause the lumbar discs to round and compress, increasing the risk of injury or re‑injury, especially for those with back problems or limited flexibility. Because of that risk, this type of movement is labeled contraindicated.

Among the options, the one that matches this description is the movement that involves bending the spine forward with little or no back support. The other choices involve different spine positions or supports: a back bend extends the spine, a deep squat keeps the spine relatively neutral with hip and knee flexion, and the plow involves extreme flexion but with specific body mechanics and support considerations.
