Bruna Lima, the utterly beautiful 20-year-old Brazilian/Italian babe you see above, calls herself a fitness enthusiast. We call ourselves Bruna enthusiasts -- seriously, just look at that booty. We could run a whole year of Hump Day pics only using Bruna's glutes. She also really knows how to wear a set of yoga pants. And the cleavage ain't hard to look at either. She's a well-rounded girl, isn't she?
