Is there an equation to figure out the amount of cals burnt by how much weight you lift in a workout? I’ve been using fitday etc to see how much Im burning but its all dependant on time.
thanks
Talk about focusing on the minutia. I understand where you are coming from, but lifting 185 on the bench v. 195 aint gonna mean squat in the course of an hour.
Basic balls-to-the-wall lifting will burn about 300 - 500 cals a hour depending on the rest periods and exercise selection.
If you are really busting ass, assume about 400 to 500 or so (not including the rise in metabolism you get afterwards, which is signifigant).
Ya I understand that but my workout partner and I are at the gym for probably 2 hours a day, but we are fartin around of course, talkin with other people, but we still get awsome workouts, but putting in 2 hours into fitday and other programs like that come out to 900cals burnt which is just rediculous.
where do these number come from??? i’d like to learn about this. how many calories burning as the day goes on as well or even the day after.
There probably is an approximate value based on foot-lbs lifted (e.g., 100 lb lifted through 1 foot 10 times is 1000 ft lb) but I don’t know what it is.
You can estimate it reasonably well by imitating on a treadmill or exercise bike what you think your average heartrate and respiration is during a workout. The estimation won’t be perfect but shouldn’t be drastically far off either.
I agree with Lonnie123’s estimate on average rate, with the exception that it may be in addition to resting metabolic rate rather than simply that as the total. In other words, 300-500 extra calories rather than 300-500 total during that period. Purely as personal estimation, I can’t prove it.
cool, thank you. i guess the approximate extra calories burnt would obviously be based on the reps generated at what velocity. i.e, strength training versus strength endurance.
the longevity of the calories being burnt would be moreso for strength training due to the added length of recovery versus a faster rate of calorie burning at a shorter period of time for strength endurance??? i would be interested in learning this exact science. it would seem very benificial to know.
Weight training results in a higher resting metabolic rate through the rest of the day, so you’re right, a given amount of calories burned in weight training is more effective for fat loss than the same amount burned with aerobics, due to immediate effect being the same amount of calories and then there being this increase as well.

I believe its called Post Exercise Oxygen Consumption. While I’m sure most of the numbers are off slightly, I have read (maybe even on this site??) that an intense weight training session, along with the 400 you burn during the session, can increase your metabolism upwards of 700 calories over the next 48 hours.
This makes sense as you can see that “we” need a significant amount more calories than the average non-lifter. While most people would probably do fine on 2,000 cals a day, that would be a fairly drastic calorie range for most of us (I hope).

I think you could probably use Feynman’s path integral formulation.
