I bought myself an exercise bike 2 weeks ago and have done 6 miles every day since. Last week I lost a brilliant 8 lb and this week I have only just lost 1lb. I really thought I would have lost more because I have also been on the wii fit aswell. I know I shouldn't feel sad because of my weight loss last week but I just can't help it. Does exercise affact anybody elses weight loss. ??
