A tiny bit more about TrImp
TrImp (Training Impulse), is a way to measure a workload by heartrate and duration. So with two workouts at the same intensity (measured by heartrate) but different durations will give different TrImp scores. So that's one way to increase workload. Another way is to increase the intensity. In theory, a short high-intensity workout (ride) can be just as effective as a longer, but lower intensity ride. That sort of makes sense right? But because the score is tied to both actions, you are going to have to increase duration in order to be able to get higher TrImps.
For me it helps to kinda think of it as lifting weights. (Now I'm not a big weight lifter so this is just to illustrate a point) Say I could chest press 60 pounds for 25 reps and reach my fatigue point. (where I can't press anymore) I could also press 105 pounds for 10 reps and reach fatigue point. So it's kinda like that. Except that you can't just do higher intensity all the time. In order to build endurance you need to increase duration.
You can use TrImp to quantify your individual workout, a particular day, or any group of workouts (like weeks or months).
