I did the second run of week 6 this evening and found it incredibly hard! In fact, if my daughters hadn't been with me I honestly would've stopped. I don't understand why I found it so hard - much, much harder than the 20 minutes from last week.
I am really worried about the 25 minutes now. Think I'll leave it until Monday rather than Sunday to give me a an extra day's rest.
Did anyone else find week 6 tough going?
