Answer contract and relax

Explanation:

To pull the rope human body muscles contract and relax those are basically muscles of arms, shoulders, abs, neck and legs. if they twitch and tighten the force cannot be produced, relaxing and twitching leads to lose the rope. tighten and contract may lead to injury to muscle fibre.contract and relax are two opposite forces that work together at the same time in case of rope pulling.

so the best leading answer to pull the rope is using contract and relax the muscles at the same time.
