Strength Training/ Calories?

I encountered this problem a few days ago and saw a forum addressing it the same day! Under cardio you have to input your strength training as circuit training!

From that forum:

You can use:

to calculate your calorie burn for weights (and about anything). I add a segment under cardio for weight lifting and put in the calorie burn according to what bodybuilding.com tells me so MFP will track it for me.

I almost always lift in supersets or even free weight circuits with no rest between exercises. At my gym for example I will do a set of squats, isolated curls and tricep kickbacks without a break. At the end of the squats my heartrate is 140 and stays fairly high through the curls and kickbacks before a bit of rest and then repeat. My weight workout lasts about 45 mins and burns a decent amount of calories according to bodybuilding.com.
