<span>The correct answer is: B. Arching the neck and back puts stress on the spine<span>.
A hamstring stretch refers to a stretching pose or technique where you extend your hamstring (underside of your thigh) to its full capacity. When performing a hamstring stretch, it is important to keep your neck straight and avoid arching it, because by doing so, you are putting undue stress and straining your spine instead of targeting your hamstrings. </span></span>
Getting a cramp while swimming is the worst that could happen to us people. I think the best answer here is to relax, float and massage the cramped muscle because, if you try to keep swimming the muscle could tighten more and could get out of hand and could cause you to drown.
