Hehe yup another calorie thread 
How do you calculate roughly how many calories you've burnt in an exercise session.
For example I do three sessions of spinning a week, each lasting about 45 minutes. When i'm done, i'm knackered and there's a rather large puddle of sweat beneath my bike.
But how many cals have I burnt? I would hope over a 1000 but tbh I have no clue?
