If you're ready to burn it up, we have a killer workout from celebrity trainer Jeanette Jenkins. Known as The Hollywood Trainer, Jeanette works with Pink and Alicia Keys, among others, and now she's going to put you through the paces to burn 600 calories. But you're not in it alone! You'll be sweating along with our own Anna Renderer as well as Jeanette's cadre of trainers — Ashley Joi, Liz Holt, and Beth Alexander. And if you need modifications for any moves, we've got you covered. Grab a towel, a bottle of water, and a yoga mat, then get ready to sweat.
