Swimming & # of calories burned

Do you wear a HRM that tells you the calories burned, or are you using what comes up when you choose that activity in the exercise list? I wear a heart rate monitor, and I periodically take the tests at the gym that tell me my anaerobic threshhold, fat burning zones, etc. Those are programmed into my HRM.

I burn way, way less calories than the number that comes up for my activity in the MFP lists or that the elliptical says I burn. So if you are using calories burned just from the list, maybe try eating half the calories to see if that helps? Since I know my calories burned is quite accurate, I strive to eat about half of them (not always successful, but that is my goal).

You cant wear a HRM in the pool (they work on electrical signals)!

I swim for 1hr (constant swimming) 4 days per week, covering around 3km if you put that into MFP it gives me a burn of around 860... but, i use something called a pool mate, which is a swim performance tracker which gives me a burn of about 760, so there is a slight difference between the two! I'd start cutting back on a few calories, maybe eat 75% to even the odds... also i trust that your swmming NON STOP in this. Also after 1hr your body burns alot less calories, about 50% less per hour, so you need to factor this in!

Personally i use a fit bit, pool mate pro and HRM (all set to my specifics), i eat around 90% of my excorsize calories back, and im loosing a steady 2lbs a week.

I think you just need to find what works for you, but i'd suggest a pool mate if your a swimmer at heart and worried about the burns your given, mine was about £60!
