6. Justin Bieber Working Out

You know the Biebs had to show up on this list at some point, and what could it be other than the pop superstar showing some skin. These shots of the Canadian-born teen idol pumping iron have been floating around the Net since 2014, when then 21-year-old Bieber decided he needed the muscle mass of a grown man to go with his expanding rap sheet. More images of the densely tatted singer lifting weights or more accurately showing off his new, improved physique can be seen in a 2015 issue Men’s Fitnessalong with a detailed description of his workout routine, for any Beliebers who want to follow their role model’s lead.
