Hi all. Need some advice. Have stuck rigidly to my healthy eating plan and been doing the couch to 5K but only on 2nd week!! I lost 5 lbs in my first week which I was delighted about. However, this week, the scales just haven't moved!!! Is this normal?? I'm the sort of person that needs to keep seeing an improvement otherwise I will just give up! Any advice, hints, tips, kicks up the bum very welcome. Thanks in advance.
