That was hard work.
I was OK until 10 minutes in and when she said "you're fit enough to do this, it's all mental now" made me think "who am I kidding, I'm not really fit enough, this is really hard even though I'm going so slow". I had to slow right down to a walk for 5-10 seconds to catch my breath then and once more with 5 minutes to go. The last two minutes were the longest of my life and the music was so SO boring that I was just thinking about how much longer I had left because I wanted to be done with it!!
If it's a struggle should I redo the week or carry on?
