I use the 15% incline 3.2 mph for 30 mins and burn around 450,I usually stop at 400 which is about 25mins or so

I use the elliptical the machine says i burn 1200 an hour. i do it for 40 minutes. However i'd assume the machine could be wrong i weigh around 250 at 25%bf. The machine can't tell a man with an LBM of near 200lbs from a woman who is 250 at 60% bf.

However i don't know if i use my extra muscle on the machine.
