6 weeks into my lifestyle change and I'm only just starting to do any exercise outside of what I do at work.
So yesterday I went for a bike ride. I don't have any technology (at the moment) so instead, I plugged my route into a website and it said that I'd burnt just over 400 cals. After further investigation I've found that almost every website or chart shows a different calorie burn. In this particular case, one site said 650+.
I've used ones that take into account your effort level and your current weight.
Can someone point me towards a site/method that will come up with 'the right' answer? Is there a right answer?
