17-year-old singer, Justin Bieber, has been hitting the gym with personal trainer, Dolvett Quince (oh, you know he's black with that name), trying to bulk up his physique and increase his stamina for his current world tour. 

Though, one would think he got plenty of exercise running into buildings, in trying not to get accidentally run over by excited, screaming admirers that may miscalculate where he is standing. 

The government should have used Bieber for a physical fitness campaign aimed at preteens and teens. It would garner a lot of public attention and hopefully do some good for millions of kids.
