How can you test lumbar flexibility?

• A. Sit and reach; measure distance between toes and fingertips
• B. Stand on one leg for 30 seconds
• C. Shoulder flexibility test
• D. Hold a backbend for 60 seconds

Answer: (A)

Testing lumbar flexibility involves measuring how far the lower back can bend forward. The sit-and-reach test uses a straight-leg forward reach, and the distance between the fingertips and toes provides the concrete measure of how much the lumbar spine (and the posterior chain) can flex. This direct test of forward bending gives a simple, standardized score that specifically reflects lumbar flexibility, which is why it’s the best choice. Other options assess different abilities: standing on one leg mainly checks balance and stability; a shoulder flexibility test targets upper body joints; holding a backbend measures spinal extension and chest/shoulder mobility, not forward flexion of the lower back. For accuracy, perform with knees straight, exhale as you reach, and record the farthest reach over several trials.
