I went to the website below, and calculated my calories burned. I am male, 32 years old, 198 pounds. I estimated my VO2 max to be 45, based on an equation I found online (max heart rate divided by resting heart rate, times 15).
It said I burned 734 calories in 40 minutes.
My question is this: is there anyone on this forum with similar variables, who does snatches with a heart rate monitor? Do you get results consistent with this?
It seems too good to be true.
here is the calculator: Calculate Calories Burned * Triathlon Training Blog
