Calories burned during HIIT exercises

megstoo

I do a bootcamp 4 to 5 days a week (1 hour each time) and it's mainly all HIIT exercises. Some days are more cardio or strength focused (yesterday for example was all strength work - I know today will be all legs with some sprinting).

Most of the HR monitors I see are only good for the stable cardio (machines). How do I figure out calories burned during HIIT sessions? I asked my trainer and he said some days could very easily be up to 1,000.

I use a Polar H7 Bluetooth Heart Rate Monitor and it works great for HIIT. I pair it with my phone and the Polar Beat app. Use that for Cardio, Running, Strength ETC ETC

By works great presumably you mean it gives you a number?

Heart rate is not a meaningful proxy for calorie expenditure where training is anaerobic. I wouldn't bother at all, that said I'd be sceptical of a 1000 cal session, that's about 90 minutes worth of sustained effort.

Personally, I just log it as generic circuit training. If you lose weight faster than you want, eat back more calories. And vice versa. Anything beyond that is just overthinking the whole thing.

Thanks, for tracking purposes I do 500, I figure if it's more that's great but I doubted it would be any less.

I have wondered the same thing about my bootcamp classes. They're 45 minutes, but I log 40 minutes of circuit training since I'm not actually moving for 45 whole minutes.

I considered a HRM, bummer to know it wouldn't be that accurate. All I know is I'm sweating like a pig afterward.

500 net for a hard 60 minute session is in the "reasonable" range. It's doggone hard to net more than 10 calories per minute.

Your "trainer" is using the age-old marketing tool: hyperbole.

If you're doing something for "1 hour each time", you're not doing HIIT.

And HRMs are a disaster for interval-y type training - they will overestimate burn rates by as much as 500%.
