To think, if that thing just focused on it's diet, and didn't waste it's time destroying valuable gym equipment, it might be better off. Lets do the math. (All numbers are approximate) Walking at 2.5 mph is about 3 Mets, she weights about 160kg. So her calorie burn per minute is 0.01753160=8.4, That times 24 minutes about 200 calories. She would have burned about 65 calories just sitting down for 24 minutes. So her exercise netted her 135 extra calories burned. Many studies have shown that overwieght people overeat after even the most moderate workouts. So, if due to working out, she is eating more than 134 extra calories, she is actually gaining weight by working out. Anyway, if there are any disgusting fats you are feeling charitable enough to try to help out, beat the idea that working out is the key to weightloss out of their fat riddled brains, and beat the fork out of their hands while you are at it.
