I have a new favorite machine. The arc trainer is flippin amazing. It was super difficult at first, i could only stand it for like 5 mins. But now, i stay on it for 30-45mins, and burn between 350 ...

I burn off 400 calories in 20mins on the elliptical.

no you don't. the readings on those machines are so inaccurate.

That's what the machine says. Whether it's true or not is another story.

it's not true.

if it is true why are you still so fat?
