I have found it really hard this week as I've had a cold and all i've wanted to do is too treat myself with really tasty (bad for me) food. I haven't done enough exercise this week and went over 1400 cals on sat so i'm really pleased. I am really proud of myself though as it's usually any excuse to pack it all in and I haven't.
I have found that when I start to wane, I log on to this site and it really helps to read about other people going through the same thing.
I'm ready for week 2 and I WILL achieve the 150 mins exercise! Believe me though, that I will find the hardest thing of all.
