I'm trying to figure out what MET values for various exercises mean. Cardio exercises seem pretty clear to me: 6 MET for bicycling means that one hour of bicycling for a person weighing 70 kg burns 6 * 70 = 420 kcal.
However, what about exercises such as weight lifting, where you need to rest between sets? Are MET values calculated to include rest or not? For example, I see in many charts that MET for weight lifting is 6. If the person weighing 70 kg trains for one hour, lifting for one minute and then resting for one minute (so the total lifting time is 30 minutes), does he burn 420 kcal or 210 kcal?
