Calories burned lifting?

John Black said:

Is there any easy way to figure out how many calories are burned in
certain lifts -- say 10 reps of shoulder presses with 50lb dumbbells
straight up and down or 10 reps of flat bench with 80lb dumbbells? Its
part curiosity and part wanting to compare a lifting workout to a cardio
workout from the point of view of calories burned. Thanks.

According to www.fitday.com:
1 minute of Weight lifting with "vigorous effort" burns 7
calories/minute
and
1 minute of Weight lifting with "light or moderate effort, light
workout, general" burns 3 calories/minute
Butthere is also the added calories burned by the added muscle from your
workouts so over time you do end up boasting your overall resting
metabolic rate.
For a more definitive answer and the best overall picture you'd be best
playing around with the tools at www.fitday.com or

Using those you can get a good idea of your intake and how much you are
burning.
