>>101350652>3 hours per day*5 hours of dancing, followed by 1 hour of physical training
to match up the numbers, you just need to watch her dance practice stream where it took her 30+ minutes to perfect a section of a single dance and this girl learns 18 dances in a busy month
Doing the math, it comes roughly around to roughly 4-5 hours and Bae has talked about the most intensive days being 8 straight hours of recording and dancing
Secondly, manual labor like lifting is a job that uses your upper body muscles primarily and is mostly repetitive static carrying hence it does not require specialized cardio. An adult male who isn't disabled is not only physically superior to woman, 15kg is nothing to him in such a field. The argument here you can make is that it's monotonous and soul crushing
Also there are lunch and dinner breaks in labor jobs as well
Dancing on the other hand is similar to a HIT activity (High intensity training)
It requires cardio and uses both upper and lower body muscles in the body but most importantly, it's very intensive on the heart rate and lungs and requires a great deal of cardio. I would reckon it's several times more exhausting as the manual labor job in terms of physical intensity for the same amount of hours, especially if it's the type of dances Bae does.
