1 hour of stairs is gonna be at least 1000 calories
If ur going level 15 for 1hr straight
No, I do 60 steps per min and burn 500 in 30 min. 60 would be over 1000.
I would be skinny asf if that were true I barely burn 400 on a good day
Should definitely burn 400 in half an hour as long as you weigh 170+
the 170+ is a bold assumption
