700 calories for a 150 lady, that would be a very hard effort and done often in a hard class. 700 calories for a 220 lean man, moderately tough. 1000 calories per hour for a 220 lean man, hard effort. 1200 may be possible but not many fit enough to hold that duration. You HR would need to be at your anaerobic threshold for most of the time and lactic would build.

I just got a hrm watch and in one class I burned like 720 calories!! I told my instructor and she said she has had people burn as many as 1200 calories in a 60 minute session!! I'm working my way up to that point!!

I got a heart rate monitor and took it to class with me on Saturday. In the 45 min class plus the cool down I was at 605 calories burned. My instructor is very intense, she use to teach on an Army base in CA to drill instructors.

I just got a heart rate monitor that tracks calories too and I am excited to try it out at spin tomorrow night. I will be doing RPM. We have the tracers on the bikes at the gym and I am interested in seeing how accurate they are. But if you can get to class 5-10 min early and get a good warm-up in it will add to your total calories and miles while you are just waiting for class to begin
I teach RPM by Les Mills spin method and they taught us a 45 minute class can burn between 530-700 calories depending on gender, weight, the amount of your intensity. So yes, I believe it is true. As a woman, I probably only burn about 550 compared to a larger man who may burn 700.

The highest work quotient is obviously pushing a hard pace with high tensions. I have observed 20-25 calories per minute during such intervals, so theoretically 1000 calories per class can be done. The obstacle is that keeping this up for the full class is something most people cannot do. Scaling it down, 700 is possible in a very demanding class
It depends on how hard you're working, how much you weigh (and how much lean mass you have). I work near an 80% heart rate for most of my Spinning classes, and I only burn around 400-600 calories in an hour, sometimes less. There are a lot of factors at play. But a good HRM is one of the best ways to estimate how much you really burn in Spinning or in any activity for that matter.
The amount of calories is related to the watts you put out or work. You can look up all the formulas. From experience using the Computrainer and other such calibrated equipment you can dial that in pretty close if you use a HR monitor and spend some time.
If I'm working very hard doing an effort averaging about 350 watts per hour it will burn more calories and my HR will end up over 90%+ by the end of that hour. If I do an effort of 220 watts my HR will be below 80% on most days.
Intensity and duration as well as power output will determine this.
I'm 201 lbs and my lean body mass is about 173 lbs, a lady I know is 150 with a lean body mass of 91 lbs. I can double the wattage she puts out in an hour so probably double the calories. In a hard spinning session of 45 to 50 min, I do about 1000. On climbs or intervals I will hit a HR of 90%+ and the resistance cranked.
We are all different and it took me about 1 year to tune the HR monitor in. Check Sporty Pal app if you have a phone and walk, run, or ride outside.
I've never seen numbers like that spinning-- and I spin 4 days a week. There is a consensus in our group that we are burning about 100 calories every ten minutes. Our class is 45 minutes long. I also know unless I have the tension cranked- I don't burn calories. There is no such thing as a flat row for me unless its cranked- my hard rate doesn't go up!
Every person is different and every day is different even for one person. I have burnt anywhere for 660 to 1000+ in a 45 minute class my norm is usually 660 but if I am having a very good or bad day it has been 1000.
The road to success is not straight. There is a curve called Failure, a loop called Confusion, speed bumps called Friends, red lights called Enemies, caution lights called Family. You will have flats called Jobs. But, if you have a spare called Determination, an engine called Perseverance, insurance called Faith, a driver called Jesus, you will make it to a place called Success.
I have a HR monitor dialed in for a pretty accurate calorie count. It took me a while checking it with other methods. Charts are not all that accurate unless you a lot of variables, but they can get you close.
Class today was 49 minutes and I burned a little over 1000, I pushed pretty hard. If I back of a little it's still 750 to 800 calories. Outdoors going super hard on a bicycle calories can hit 1300 to 1500+.
Hard walking up hills for 60 mins are 3.5 mph about 400-500.
Easy cycling about 400 per hour.
I never check water running but that would be really high if the intensity was high.
I'm at 202.8 lbs with around 170 lbs of lean body mass. My HR max is around low to mid 180's. In a really hard spinning class I'll hit 166-172 on the hard efforts. On a super hard cycling effort I'll be 177 to 183 for almost the entire hour. Walking up and down some hills as long as .75 miles at a 3.5 mph pace my HR might get to 135, most times its below 100. I'm 56 and I have friends that at the same age their HR will max out at 155.
These numbers are specific to you, everybody is different.

90 minute class I burn between 750 and 850 calories depending on the intensity but I am a very fit person aerobically so it takes me more to get the calorie burn. A 60 minute class I would be between 500 and 600 calories
