Don't Miss:

Throughout this season of The Biggest Loser, coach Jillian Michaels has been wearing a personalized initial necklace with “JM” done up in gothic lettering, and it’s hard not to notice the piece as she’s bending over the contestants shouting (for their health!) week after week. So when we caught up with the fitness guru at the Heart Truth Red Dress Fashion Show, we asked for all the designer details. “Jennifer Fisher made it for me and gave it to me, and I love it,” said Michaels. “I thought that was so cool of her, so I wear her stuff as often as I can to give her a shout out.” The best part? It can be yours! Snag it in your initials for $1,300 at jenniferfisherjewelry.com.

The Biggest Loser’s Jillian Michaels isn’t just training people anymore, she’s dressing them, too! Michaels just announced that she teamed up with K-Swiss to launch a line of workout gear named The Jillian Michaels Collection by K-Swiss. The vintage-inspired line features sweats, leggings, bras and tees in shades of pink, green, aqua, white and black, all priced from $32 to $90. The best part is that a portion of the proceeds are going to the Alliance for a Healthier Generation, a non-profit organization devoted to reducing childhood obesity rates and empowering kids to make healthy lifestyle decisions (Michaels was overweight as a child). Nordstrom and Amazon.com are set to stock the collection by mid-April. Check out a sneak peek in the gallery!
