Missed this thread when it was posted - I’m not sure Low volume on its own is the best approach a KQ attempt, but I think Ive heard some elites use Low volume as a part of their plan, eg that TR covers their indoor riding but they have a plan of outdoor rides as well, plus swim plus run of course.
I tend to use mid volume plans even if I can’t do every bike session, and substitute outdoor for indoor rides.
Let us know what course you’re doing in this thread?
