The world was buzzing about Beyoncé’s super svelte, post-baby bod earlier this year, proving that the sexy songstress is back and better than ever. The 31-year-old dynamic diva gained 50 pounds during her pregnancy, yet just months after giving birth, she was already showing off a newly trim and toned figure. But getting that bodacious bod back in fighting form wasn’t such an easy task. Bey worked out three to four times a week for an hour at a time with celeb trainer Marco Borges, doing a ton of cardio (walking, running, and sprinting) combined with plyometric exercises, resistance work, and calisthenics. All hail Queen B, because she sure does “Run the World!"
