In an amazing transformation of hardwork and will, 35-year-old opera singer Olivia Ward won Season 11 of the Biggest Loser by dropping 129 pounds. Check her rocking Vrksasana (Tree Pose) … though we wish she wasn’t resting her foot on her knee joint.

Yoga is part and parcel of the of the five-month journey that contestants undertake on their path from obesity to health. Biggest Loser trainer Bob Harper, who studied with Bryan Kest, is a huge yoga advocate, and has made a couple of yoga DVDs. Outgoing trainer Jillian Michaels released her own high-octane yoga DVD this spring.

Ward told Us Weekly that she plans to keep the weight off with five to six spinning workouts a week. We hope someone gives her a yoga mat!
