Which muscle is associated with the cue 'reverse surfer'?

• A. Adductor magnus
• B. Adductor longus
• C. Gracilis
• D. Semimembranosus

Answer: (C)

Understanding how a movement cue maps to muscle action helps you identify the right muscle. The phrase “reverse surfer” suggests a inward-directed leg movement with knee bending, which emphasizes muscles that pull the thigh toward the midline while also assisting knee flexion. Gracilis fits perfectly: it’s a slender muscle that crosses both the hip and knee, contributing to hip adduction and knee flexion. That combination matches the cue’s motion, making it the best match. The other muscles either act mainly to adduct the thigh without involving knee flexion (adductor longus and adductor magnus) or are primarily hamstrings involved in hip extension and knee flexion without adduction (semimembranosus).
