Just checked the video for this progression, it has changed from 5x60s to 5x30s. Did the coaching team decide that 60s was too difficult and the appropriate time was 30s for this progression?
I was originally going to post that I can't progress to 5x60s, I got to 60,60,60,60,50 but since then I've been regressing and today only managed 60,60,45,40,30. But if it's changed to 5x30s then I can progress now.
What is the situation with this progression?
