Sorry, posting in here for traffic. 
I'm probably about 20 pounds/9kg overweight.
I'm finding it SO hard to motivate myself in to exercising and the only exercise I can do is fast walking/very slow and sporadic jogging (fucked knees).
I look a lot at the health app on the iPhone but think it's probably not so accurate as to how much or the type of exercise I'm getting.
For those of you that have fit bits or similar, did they help you drive to lose weight? If so, do I need a model with all the bells and whistles? Which brands are best? Did you lost interest in them after the initial purchase?
I'm bordering on getting one and dh says he'll buy me a top of the range one as an early birthday present if I want but reckons I'll be in to it for a couple of weeks then it'll be wasted money.
