A mix of cardio and strength?

    Are you asking how many calories you burned? There's no real way of knowing.

    Wow, so many variables... If you give a lot more info on the details (your weight, age, exercises done, weights, sets, reps, intensity level, type of cardio...) someone might give you a range of calories you may have burned but that's about it. Tough one to guess. Good luck to you!

    Get a good heart monitor that estimates calorie burn and allows you to put in variables such as your fitness level, age, weight, etc. Even then, it's only directionally correct. (By the way, never trust the calorie estimates on cardio equipment in the gym. For many people, the estimates are way off, often on the high end.)

    The best estimator I've found for those type of situations is to use a heart rate monitor. If you want MFP to give you a quick estimate go to the cardio section in the exercise part of your diary and add 30 minutes of circuit training. It won't be perfect but it will give you a ballpark.

    Use a heart-rate monitor like an inexpensive Polar FT7 or something similar. As others have said there are a LOT of variables, but a decent HRM should at least give you a relatively accurate estimate.

    Welcome to the site.

    When I log my workouts, I log the cardio by minutes performed BUT I only log 50% if using MFP numbers because it seriously overestimates the burn. e.g. If it's 20 minutes on the treadmill, I'd log it as 10.

    I personally don't log strength training towards my calorie burn. Unless you're spending hours in the gym or have so little rest between sets that it IS a cardio workout, then the caloric burn is minimal.

    I think I might log that under circuit training?

    Yep.

    People are suggesting using a HRM, but those are only accurate for steady-state cardio like running, walking, biking, or swimming. Certainly not for anything with intervals, and definitely not strength training.

    The only rough estimate that has any scientific basis is: two sets lasting approximately 45 seconds each will deplete around 5g of carb , if you assume 4 calories per gram that's 20 calories per 2 - 45 second sets . Anecdotally using an hrm , a work out usually nets me 100 to 150 calories, which is not far off the predicted value. If your sets are shorter or longer than 45 secs just pro rata the value.
