MFP log in exercise?

[Pittsburgher 261]

So i logged in my exercise on my fitness pal and for 30 mins on the treadmill it said 436 calories burned, and 30 mins swimming 339 calories burned. My question how do i no if this is actually accurate? I can look on my treadmill and see how many cals i burned but what about swimming?

Any device to wear that can track calories burned accurately? Maybe waterproof for swimming.

I looked into the garmin watch....i do believe it is.waterproof but for bikers? I.just want to track calories burned.

Does anyone track calories burned?

I use a heart rate monitor because I do DVD programs. I found MFP overestimated the calories burned by a lot. Mine is not waterproof but I think they make some. I use a polar chest band and watch.

I recently purchased Polar watch with the heart rate monitor (chest band). I have not used MFP in a long time but I need to get back to it, in fact I think I'll head over and reset everything right now. I'll let you know how they compare as soon as I find out.
