Could you be any more vague/non specific? :P

I'm with Scrap... I've shed most the little fat I had since I started working 'part time' (now up to 30 hours a week on average :P on top of the gym I work in) in a cinema whilst I'm at college.

Not a lot of hard work but I'm constantly brisk walking up and down the corridors all through out my shifts which can range from anything to 4 hours to 12 hours...
