Lauren Whitmore Powers knows what it's like to be out of shape—she was more than 80 pounds heavier before she discovered boot camp. Her transformation from heavy to fit inspired her to become certified in TRX group suspension training, Schwinn cycling, and Level 1 CrossFit so that she could help others achieve the same kind of results. Today, she acts as program director of Boot Camp Revolution and Total Fitness Revolution, working alongside a team of 12 other instructors that includes lifelong athlete Da'Mon Mayers, second-generation yogi Heather Ambrosi, and Basheerah Ahmad. Basheerah has worked with other elite trainers like Jillian Michaels and has worked out celebs like Carrie Underwood and Vivica A. Fox. This team of trainers helms one-month boot camps and one-on-one training sessions, as well as small-group classes that cover the ins and outs of TRX suspension training, Pilates, yoga, and Zumba.
