Starr programming question

[zepled37]

Why in the Starr model do you add days first at medium intensity instead of adding days at low intensity first? Wouldn't the additional volume over the week still help even if the intensity of the added day was lower?

This is for example if you are moving from a 3 day per week routine to 4 days.

Thanks.

We have found that there is very little adaptive stimulus from lower intensity workouts, and that intermediate lifters do not respond to volume changes due to low-intensity work the way more advanced lifters do. An added workout at the intermediate level needs to actually drive adaptation to some degree to warrant its addition to the schedule.
