Victoria's Secret models don't just waltz onto the runway looking ~flawless~. It takes a shit-ton of work to get them in such great shape — and lots of help from people like Justin Gelband, the certified fitness trainer behind ModelFit, an exclusive boutique fitness studio in New York City. He's currently training nine of the women walking in this year's Victoria's Secret Fashion Show, including six of the 15 Angels. The show tapes Nov.10 and airs Dec. 8 on CBS.
