Martin's goal is to increase his leg strength. look at these entries in his workout log and determine which principle of training he is most likely focusing on in order to reach that goal.

When you're doing aerobic activity, such as walking or biking, exercise intensity correlates with how hard the activity feels to you.
Exercise intensity is also shown in your breathing and heart rate, whether you're sweating, and how tired your muscles feel.
Exercise intensity is a subjective measure of how hard physical activity feels to you while you're doing it — your perceived exertion. Your perceived exertion level may be different from what someone else feels doing the same exercise.
For example, what feels to you like a hard run can feel like an easy workout to someone who's more fit.
Your heart rate offers a more objective look at exercise intensity. In general, the higher your heart rate during physical activity, the higher the exercise intensity.
