How you do define success? For the “Mission Makeover” ladies, it’s about muscling through...and not surrendering. With the help of Femme Factor, they learn about a new pre-workout secret weapon designed just for women. And just how are their bodies doing? Thanks to Avery Dennison, they get to the heart of the matter...with data on their breathing and heart function. And speaking of hearts-to-hearts...South Beach Diet’s Elise Donahue sits down with the gals for a final debrief, reviewing their journey and looking forward to what’s next. We wrap up the week with a group field trip — Mission Makeover Mentors — Jessica, Adriana and Meryl — take the girls on a rock climbing expedition.
