Seriously? I burned less than 200 calories?

I feel the same way sometimes... It's like really?! I just did all that for how many calories?!

Try to do your reps faster maybe to get your HR up, and take less time between breaks. Should burn more calories and in less time. Either that or run for a bit afterward to get some extra calories in.

Do cardio intervals between your sets, like a minute of jumping rope or burpees. It really raises the heart rate and burns those calories away. Combo lifting moves also elevate the heart rate like crazy and allows you to use your gym time more effectively.

In P90X we normally accompany weights with pushups, pullups, or dynamic leg-work ... average burn is about 400-500 calories (unless you're super fit).

Hmm maybe I did burn more then cause this is a class I take at the gym and we do multiple moves all at once and I really break a sweat!

Use a HRM, and you'll know for sure :-)
It's a worthwhile investment...trust me on this.

You have to remember... your burning a lot more fat than calories than you would with cardio. You're also building muscle.. I've been doing body pump for about 1 1/2 to 2 months now 1-2 times a week. I still haven't lost any weight (stupid plateau) but I have built some sexy calves and some big ol' biceps!

Just keep with it! Drink your water and have a good protein/carb filled snack after to help build up them muscles!

First of all, you cannot count calories burned during strength training. There is no way to do it accurately. So if you are just lifting, the actual calorie number from the exercises themselves is minimal (I consider it insignificant, but others take issue with that word, so I changed it). It's a waste of time to try and quantify it IMO (and, no, HRMs cannot be used either--http://www.myfitnesspal.com/blog/Azdak/view/hrms-cannot-count-calories-during-strength-training-17698).

Mixed-activity classes are a little different--examples: circuit training, cross fit--any activity that has a cardio component. Even with that, however, the HRM calories will be significantly off--20%-30% or more.

Some people feel it is helpful/motivating to have SOME number to claim as "workout calories" --if so, then putting down 150-250 (depending on body size and workout duration) is probably OK.

The problem is not that strength training is not effective in burning calories and promoting weight loss. It's that there is no good way to quantify that effect in terms of calories. The main reason is that there is so much variability in types of programs and in individual response.

So, lift heavy and lift often. But don't go nuts trying to count the calories.

Use a Heart Rate Monitor. I got mine from a sporting goods store. They run around $100 for the basic kind. If you get a Polar HRM, the machines at the gym will pick up the signal and display it on the machine.

Trust me. $100 is SO worth it. Then you don't have to guess at how many calories you're burning. It's probably more than you think!

Remember that while the caloric burn during straight weight lifting might not be as high as cardio activities, it is crucial if you want to preserve your lean muscle mass as you lose fat. I think it is very eye-opening and motivating to also track your body fat percentage in some way as you lose weight. You need to keep challenging the muscles or you will lose that along with the fat, which is no good!

I do this! Luckily my scale tells me my body fat % as well as my water %. I also do measurements 1-2 times a month on everything!
