B. Tedium

Explanation:

As you can see from Martin's exercise schedule, he is trying to increase the strength of his arms through a variety of exercises, which are very different from each other. With that, we can see that he is trying to avoid tedium.

That's because if he spends all week doing just one type of exercise, for a long period of time, his body can relax and no longer show any results for physical activity. With that, we can say that the body enters a state of tedium and the best way to avoid this is to do different exercises, like Martin.
