Wear or not to wear...

[Mikey7921]

I track my food intake and cardio on myfitnesspal which is synced into my fitbit.  I also log in my weight training manually on my dashboard.  I feel like I'm recording twice if I wear my fitbit while I do my workout and cardio.   Any thoughts?

Which model do you have?

The One allows you to time your activity. Which I use everytime I exercise and then it syncs to fitbit.

I dont manually log anything unless its weight training and swimming.

Anything step based I use the timer.

I think that as long as you enter the start and end time in your manual logged sessions, you're overwriting any data the Fitbit picked up.

If I wear my fitbit while cycling. It shows my activity automatically by downloading. So if I also long my biking miles in the program will it show that I burned more calories than I actually did. For instance I biked 34 miles today and walked 5. but my app is show I walked 12.2 miles. Something is wrong.

No, because as Mary said when you log an activity the calorie burn you logged replaces Fitbit's estimate. Whether what you log is what you actually burned is a different matter. All calorie burn numbers are estimates and if you use different types of estimates (heart rate monitor, fitbit, MET charts, cardio machine readings, GPS tracker estimates, etc) you will likely see different calorie burn estimates for your same stats and the same workout. Fitbit isn't able to estiamte non-step or resistance activities well, so I would log cycling. The distance doesn't really matter in this case. Cycling a mile and walking a mile are not equivalent and your cycle distance isn't applied to your walking distance. What adds to the confusion, with logged activity when you log it it replaces fitbit's calorie burn but it keeps the steps (unless you log walking or running with a distance). The distance is just based on the step count and your walking and/or running stride length. If that bugs you, it may be a good idea not to wear the fitbit for cycling. That may work fine for gym workouts, but for people commuting/traveling via cycle it may not be practical. Some people like the minimal steps they get credited for cycling as some challenges only count fitbit tracked steps/movement and exclude manually logged activity.
