JUSTIN BIEBER WORK OUT WITH US MAGAZINE

Justin Bieber is working it out.

The 17 year-old singer is putting a lot of effort into his health and his physical stamina so he can perform nightly on stage. Bieber works with a personal trainer and eats pretty healthy.

His vocal coach, Jan Smith said: Although Bieber occasionally indulges in junk food like Doritos and Fruit Roll-Ups, “He’s pretty good about his diet,” Smith said.

Even Rihanna has admired the Biebs work. She said on twitter after the two had dinner together:

“Justin Bieber just flashed me his abs. Wow! He actually had a li’l six pack!”
