From training the Biebs to The Biggest Loser!

Justin Bieber's personal trainer, Dolvett Quince, will join the NBC series as a trainer on its twelfth season, set to begin production this week.

"I couldn't be more excited about joining The Biggest Loser as their newest trainer," the Atlanta-based trainer tells Us Weekly in a statement. "This amazing opportunity allows me to use my expertise to change lives one rep at a time, and encourage contestants -- and viewers -- to find strength beyond muscle."

Quince (seen at left working out with Bieber during a Dec. 16 tour stop in Greenville, S.C.) also designed a fitness and diet plan for the 17-year-old singer for his "My World" concert tour.

The Biggest Loser's new season, set to air in September, will also feature newbie trainer Anna Kournikova and veteran Bob Harper.
