Spor****ch vs Fitlinxx

Yesterday I bought a spor****ch that calculates the cal burned using your heart rate age and weight  Fitlinxx at the Y does the same thing but you have to guess at the intensity because they have no entry for heart rate.  I wore the watch to water aerobics this morning and burned 884 cal in the hour class.  I was only guessing for the Fitlinxx entry and going with strong and it was telling me 554.  Highly recommend a spor****ch to anyone doing those last pesky pounds like me.  I couldn't start the weight lose process going again because I can see now I was not eating enough cal.  Switched to beef  for 1 meal and added almonds.  Will add another protien drink if necessary. That should take care of the extra calories I need to eat to support my burn ratio. 125  pounds here I come!
