I have a Fitbit and I sync with MFP. Yesterday, I did a lot of walking and noticed it added 256 calories to MyFitnessPal. However, if I do something more substantial like my strength/metabolic training routine or a cardio class, I get less calories. I understand that Fitbit is step-based, and I probably made the wrong decision in gadgets. However, I know some of you have Fitbits and also do exercise that isn't step-based. How are you managing this?
