Pumping hard is supposed to burn calories... So my gym started a cirquit training program that tracks the participants' heart rate and gives an estimated burned calories. You get a bunch of different exersizes and at every one you have to get your heart rate up to 90% aerobic (180 for me) as quickly as possible, hold for a total of one minute, then rest for 30 seconds.  Every time I'm competing against the others, there's a fatass trying to do keep up. I'm training mostly for endurance, and have difficulty getting my heart rate high enough, BUT THE FATASSES REACH 90+% EASILY. I mean, walking at a brisk pace (6kph, ~4mph) gets them to 93% of a sustainable heart rate!!!  It's just pathetic. Waddling for a minute and they're huffing and puffing like there's no tomorrow, while humans have to actually work out to break a sweat.  The kicker: after an hour the humans burned 800-1000 calories, whereas the lardbarges reached maybe 400. The trainer now focuses solely on the actual humans. They've all given up trying to improve a fatty.  Fats truly are incompetent, and nobody wants them at their gym.
