I go to spin class and it gives me kcal and kj burned but I don't input my height/gender/weight.
My question is, are those burn numbers absolute or are they weight relative? For reference, I'm roughly 220 lbs and I've been "burning" around 300 kcal/hour which seems a little low.
Don't get me wrong, I'm definitely not putting out very high watts yet (there's been a lot of improvement in my averages over the last couple of months in terms of watts/miles "ridden" per hour) but if 1 mile run/jog is ~100 calories and I can do 4+/hour, and I feel like I'm exerting significantly more weight effort on the bike, shouldn't my burn be higher?
I guess I'm hoping that I'm burning more due to my (relatively) higher mass. Plus, my little HR enabled FitBit is giving me higher calorie burns. FitBit has always overestimated, but rarely triples what any other "calories out" meters estimate.
Thanks in advance!
