Molly Sims may have genes to thank for her long legs, but that tight tush and those toned thighs? She’s earned ’em. The Project Accessory host exercises every day, including four weekly workouts with Maria Kelling, a Tracy Anderson Method trainer. While the dance-inspired sessions sculpt her entire body, the focus is often on Molly’s lower half— and these three moves are always in the rotation. They target the legs and butt from multiple angles, so every part gets attention; and the higher-than-usual reps (up to 40 of each exercise) fully tire out the muscles, which is key for strengthening. Do these three times a week and show your DNA who’s boss!
