Can anyone clarify this for me please....

I understand that BMR is Base Metabolic Rate, which is basically the number
of calories required to 'live' assuming no other activity, ie.... if you
stop in bed all day...

On top of this, you will have exercise (due to workouts), and 'normal'
activity calories burned (ie. those burned, which are not related to
'workout' but due to normal day-to-day activity)

So.... Calories burned = BMR + 'normal activity calories' + exercise or
workout calories

Is this correct?

Is there a name for BMR + 'normal activity calories'???

Thanks

pretty much, yes.

but keep in mind that your body isn't a bomb calorimeter, and that all
the numbers you get from various 'calories burned' calculators are just
estimates. they're a good guide, but they're not exact.

Yes, but it is easy to overestimate calories burned by activity.

May I suggest using Fitday to measure your intake and then use your
weightloss rate to calculate your burn rate. This should give you a number
that can be used to estimate what Fitday intake you should have for a given
desired future loss rate.

I would concur with that. I cycled 130km today. My HRM claimed I'd
burned in the order of 6,000 calories - but I would really doubt that
amount; probably half that would have been more reasonable.

The HRM can only make a guess based on my HR, weight and age.

I think whatever you actually use, as opposed to what you would have used had
you stayed in bed all day, is called "active caloric rate" or "active metabolic
rate".

Be careful to avoid double counting. Various BMR calculators already
include everyday activity in their calculations. (the fitday.com one,
for example) We had a poster here who thought that she was burning an
insane amount of calories, because she had a pedometer and it ticked a
lot when she was cooking food etc. Surely, she did not burn nearly
close to that incorrectly computed amount of calories.
