Which of the following is a commonly cited benefit of stretching?

• A. Decreased blood pressure
• B. Increased flexibility
• C. Reduced bone density
• D. Increased resting heart rate

Answer: (B)

Stretching is most often associated with enhancing flexibility—the ability of muscles and connective tissue to lengthen and joints to move through a wider range of motion. Regular stretching helps lengthen muscle fibers and improve the elasticity of tendons, which translates into greater joint mobility, better posture, and smoother movement in daily activities and sports. Because flexibility is a direct and observable outcome of consistent stretching, it’s the benefit people most commonly cite.

The other options aren’t typically viewed as primary outcomes of stretching. Resting blood pressure isn’t reliably lowered by stretching alone, and any small, temporary cardiovascular changes aren’t a primary, lasting benefit. Bone density comes from weight-bearing and resistance activities, not stretching by itself. A higher resting heart rate would generally indicate stress or lower fitness, not a benefit of stretching.
