I am going downhill skiing this weekend and was wondering whether any of you is wearing the fitbit while skiing to count the steps to the lift, back to the hotel etc. or is it better to use HRM and then just log in the activity to MFP?

I'd probably just use the heart rate monitor.

You could use both--the fitbit for steps and the hrm for skiing. I don't think fitbit would be very accurate for skiing since it involves a lot of gliding. I am sure you would legitimately get a lot of steps and floors though. It is harmless to wear both if you want, I guess I would just be worried about losing or damaging the fitbit and a hrm is waterproof and usually larger and more secure.

Hmmm... About logging. I would probably log it to fitbit or just be mentally prepared for a negative adjustment. The reason is that most hrm's include bmr in the calorie burn--this is what you want since your logged activity (however you log it) is replacing your total fitbit calorie burn for that time. But one issue with longer duration activities, mfp is designed to avoid double counting your calorie burn so your mfp logged exercise is excluded in your adjustment. So to meet or exceed your non-exercise activity level you need to burn those calories in your time outside the logged exercise. This gets a little more challenging when you log more than an hour or two of activity because your bmr for that time is also included. So for long activities it can be pretty difficult to meet your MFP "calories burned from normal activity" (found in mfp goals page) and negative adjustments are quite likely. You should be fine if you are okay with that. You are still burning more and allowed a higher allowance than if you were at home or work all day.

True. Thanks a lot Kimsied. This is very helpful.
