<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>
What is not working properly... please reword and I'll be happy to help . Each answer is specific that is ehh I am answering to make sure you get the correct answer
I believe that you shouldn't use l<span>ow intensity (light weights) if you want to build muscle mass.
</span>These types of weights won't help you much define the muscles you want to have, as opposed to free weights, weight machines, and high intensity (heavy weights) which definitely will. So if your goal is to build muscle mass, avoid light weights.
