My coach has never once asked for my journal! She never even asked me to keep it
I keep track on my own in my little calendar so that I can monitor any changes. If I have a really good week one week and then I find that I am struggling, I will go back and look at what I did on that good week so that I can do it again. This comes from years and years and years of keeping an exercise and food journal. It is now 2nd nature. I feel weird if I don't write my food down
