How hard you train is about the effort level you put into each session, which is intensity. Intensity means working closer to your maximum effort—lifting heavier weights, running faster, or cutting rest to push your body harder. The other parts of the overload model describe how often you train (frequency), how long each session lasts (time), and what kind of exercise you do (type), but they don’t describe the effort per session. So the component that best matches “how hard you train” is intensity.
