Hi, Im trying to lose weight and want a pedometer ( the one that records steps) so i can try reach my goal of 10,000 steps a day..

The problem is i want to wear it to school ( and out and about).. me only being 15 years old i dont want a chunky one that sticks out of my clothes and makes it obvisous..

So could anyone recommend a slim, well hid, preferibily water proof one thats not to dear? and tha I can buy in The goulburn valley area , Victoria ( australia)
