I’m wondering if it is meaningful to adjust the training plan in the following way:
for example week 3 training one is “Mills”. My idea was to replace mills in this case for Mills+2 and so on for the rest of the training sessions.
Is this a correct way to boost the intensity of the training without adjusting the structure of the schedule or does anyone here have other suggestions?
I’d say that it depends on how the workout changes between alternative versions. In some cases it’s a change in volume (i.e. interval length or number), and so these are are a great way of increasing TSS while targeting the same systems. Other alternatives change the intensity rather than the volume - I’d be a bit more careful when switching to these workouts as they may shift the workout into a different target zone (e.g. Endurance to Tempo), and thus move away from the desired outcomes of the workout.
