I have been doing okay with my MyFitnessPal. Since I recently added exercise to my week routine I am have a few questions on my calorie burn. I have learned that I do better on the treadmill, elipticals (sp), and bikes with music. I workout at the YMCA. They have lots of Lifecycle machinesetc.. When I plug in my iPod, the computer saves my workout to a Nike site. I am not yet a member of the site but the results that show up on my iPod, the Lifecycle machine and my MyFitnessPal all differ. As it changes my diet plans, I just want to know what is the best number to use. What do you think?

Example... Walking at a brisk Pace 18 mins=
MFP 114
Nike 93
LC 84

Please Help!
