Just to confirm, you’re looking for TR to prescribe your workouts as progressions of the same workout format?
You’d like a 4x10 one week to progress to 5x10, and 6x10 the week after. Is that right?
If so, there isn’t a way to achieve that with an adaptive plan since we don’t think that’s the best way to train, but if you’re wanting to simply find those types of workouts yourself, you could try searching for the specifics in our workout library.
For example, below are the results of searching for 5x10 and 6x10 Threshold workouts.
As you can see, there are only 30 5x10s and 13 6x10s, so finding something that’s close to what you’re looking for shouldn’t be too hard. You can further filter/sort the results by duration, workout type, difficulty, etc.
Let me know if this helps get you where you’re looking to go!
