MFP Users: Calories used in exercise?

[dmxm]

I'm new to My Fitness Pal (only been using it for a week) and I am surprised by the amount of calories they allow for exercise.  For example, swimming laps for 45 minutes at a fast or vigorous rate equals 612 calories, cycling at a fast speed (16-20 mph) for 90 minutes equals 1470 calories (what?).  Do these seem high to you?  That seems like a LOT more calories to add to your daily intake if you are trying to lose.

Yes, the calorie burns are overly generous!

Agreed. Personally, I set my own calorie count and I don't "use" my calories that I've burned in exercise.

[Wines Not Whines]

Yes, their calorie counts can be off. I created my own exercises with calorie burns based off of my HRM.

I agree, WAY off. I use my HRM and enter my own calories.
