It is going to require about 400 Calories per hour to do this type of activity, you do it over 10 hours, it's going to require 4,000 Calories just to do it over 10 hours, and then we are assuming that the rest of the day you are going to walk around, maybe you cook dinner, eath breakfast, sleep some of it, we are assuming the other 14 hours of the day are going to be about 100 Calories per hour, and so this is the total if someone were to using this techique work for a total of 10 hours, this is how many Calories they would consume in the day.
