what he said, but they are never accurate.....usually calculates more then you actually burn

i used to go by the what the machines said, then i gave up on the gym, now i just play soccer for about 2 hours everyday, nothing but running, lost 3.5 inches off my waist in 2 weeks. dont be super concerned the exact number, just eat in healthy moderation and excersize and you will lose the fat.
