Statistical Results (See Bar Graph)

•    According to The US Center for Disease Control (US CDC), 17% (or 12.5 million) of all US kids between the ages of 2 and 19 are obese.

•    Compare the US CDC data to the following 492 kid study containing BMI data from 290 boys and 202 girls who’s ONLY qualification was, THEY COULD ALL DO AT LEAST ONE UNASSISTED PULL UP.

•    Once identified, BMI scores were calculated for all 492 kids.

•    As the result, according to this 492 kid study/bar graph, 0% (i.e. NONE) of the 202 GIRLS were obese, which is another way of saying, the odds were 100% AGAINST GIRLS BEING OBESE if they can do at least one pull up!

•    As the result, according to this same 492 kid study/bar graph, 2% of the 290 BOYS were obese. Thus, the odds were 98% AGAINST BOYS BEING OBESE if they can do a pull up!

•    Therefore, this empirical data overwhelmingly confirms the hypothesis contending that the odds of kids who can perform at least one conventional pull up being obese are somewhere between microscopically small and non-existent.
