If you're trying to drop pounds you MUST count your calories. I have recommended using "My Fitness Pal" for doing so. However, there is a entry each day that asks for your exercise and then tells you how many calories you burned working out. It then tells you that you have that many more calories to eat.
Do not enter your exercise into your daily log. You need to eat the same amount of calories each day whether you worked out or not.
If you eat more calories because you worked out then there was no point in working out.
