Hi Bee

Honestly, I would not worry about it too much - what they're trying to do is help you lose weight or understand how you can lose weght by telling you how much energy you are burning when you train. The theory is that in order to lose weight, you have to burn more calories than you take in. You take calories in through what you eat, and you burn them through exercise - they are a method for expressing energy.

Now, the problem with trying to count this is:

Firstly, you don't know that this number is accurate - it could be off by as much as 20%. In fact, it sounds very high, in fact, impossibly high for one hour of exercise. That figure of 1818 Calories is therefore major inaccurate - that's probably more like how much energy you expend in an entire day. Again, however, this is never 100% accurate - you might be burning 1000Cal, in which case you're off by 818!

Then the second thing, of course, is you need to know how much you take in. And if you think about this, it means you have to weigh all your food, read the labels, measure exactly what you eat and drink and then work out that you are taking in less than you lose. This is of course a riduculous strategy - you cannot "micro-manage" your diet. What you need to do instead is just say that you are going to do this exercise, which sounds great by the way, and then make sure you are eating well. What does that mean? It means a balanced diet, healthy foods, everything in moderation, and not eating too much or too little. Be careful about eating too little - it can be just as bad as too much.

If you do that, then you will lose weight, but don't get hung up on numbers - too much analysis causes paralysis! Just go for 5 days a week, and see what happens.

Good luck
