Tracy Anderson has changed the lives (and bodies) of millions of women with her intense, chiseling workout, The Method, which targets small, accessory muscle groups to help create a lean, lithe, strong physique. “Tracy has kicked my formerly sagging ass into shape and I will be forever grateful,” says GP. To supplement sweat sessions, Anderson has created a line of delicious, organic protein bars in really amazing flavors. Even if you’re not a bar person, they’re addictive.
