So I noticed another user makes claims to burn 3500 cal per workout. Im assuming they have like a nike+ or something that tells them how many they burned during a run..but like that's a pound! How is this possible and is this safe? I'm usually happy when I burn like 600, nonetheless i'm never really sure if I truly burned that many because my heartrate jumps like crazy...
anyway some enlightenment would be lovely
