Kelly Osbourne – Best Bikini Bodies
Weight-loss success story Kelly Osbourne is proof that with the right determination and mind-set, anyone can lose weight.
Stints on 'Dancing with the Stars' and personal trainers help too. But you've still gotta sweat it out.
Kelly says dropping the pounds completely changed her life.
Her routine was created by trainer Sarah Hagaman, and Osbourne does the hour-long "burning" and "firming" regime two to three times a week.
See the exact routine here and find out how you can recreate it at home using things like a Bosu (balance ball), a body bar (aka an expensive weighted metal stick), or dumbbells.
