Kettlercise, calories burnt
I never heard of Kettlercise before so looked at some videos.
Kettlercise doesn't look very demanding. Less heavy breathing than my 12 minute/mile pace jogs.
There are very impressive claims about how much calories Kettlercise can burn, like 657 calories in 45 minutes (24yo F, 5'6", of unknown weight)
I tried using the calories burnt as function of HR formula* on this page:
Is it possible to measure calorie burn from heart rate alone?
That formula comes up with numbers I think are credible for my calorie burn when I am jogging (*I have a pretty good estimate of my real VO2MAX).
But the HR that would be required for a 24yo female to get to 657 cal/53 minutes, requires all kinds of extreme values in the formula above. VO2max = 50, 70 kg, avg HR = 195. Do those numbers make sense(??) Is the formula that inaccurate?
Or would I be right to think that Kettlercise energy expenditure is probably being over-hyped?

Exercises with kettlebells can be as hard as barbell work, sprinting or high end sport activities if done correctly.
'Kettlecise' sounds like a group class which is typically aimed at anybody. So it might not be suitable for someone already quite fit.
Try it out and then increase the weights as necessary. A 8kg kettlebell in a class feels a lot different to a 24kg one.
Much like a jog and a sprint are essentially the same but completely different.
