Which of the following is listed as a contraindicated exercise due to misalignment or forward bending?

• A. Shoulder press
• B. Sit-up
• C. Bicep curl
• D. Unsupported forward flexing

Answer: (D)

Folding the upper body forward without any support puts the spine at risk when there is misalignment or instability. Unsupported forward flexing lets the spine bend excessively under load or during a movement, which can worsen pain, compress the discs, and stretch or irritate the back muscles and joints. That’s why this particular movement is listed as contraindicated.

The other options involve different actions that don’t inherently require the spine to bend forward with no support. A shoulder press primarily challenges the shoulders and arms while keeping the spine neutral with proper posture. A sit-up does involve spinal flexion but is typically performed with contact or support and is a different way of engaging the core. A bicep curl moves the elbow and forearm without significant spinal bending.
