Weight Lifting & Calories Burned

I was wondering the same thing. I found a site that displays the calorie burn per hour for various weight lifting exercises. The problem is, I do heavy weights with low reps so each set is a minute or less. Barbell Squats, for instance, burn 408 calories per hour so for 3 X 1 minute sets, I would burn only about 20 calories. That seems low to me but here is where I got the info: http://www.fitclick.com/exercises?Shoulders&bpid=3 It seems like duration of effort, rather than intensity of effort, is the key to burning calories.

I wear a heart monitor when I lift. To me, it is the only way to get an accurate calorie burn since everyone is different. When I log it into MFP, I use the cardio section but title it "Lower body" or "Upper body", etc.
