Are these exercises calories correct?
I am 64, female, currently 189 lbs. At the gym I love using a machine called Precor, it is a stepper/stair climber type of equipment. I enter my details, do the interval programme with moderate exertion,it tells me that I am using 11.2 calories. It seems rather a lot. I stayed on it for one hour and go over 600 calories.…
