The 39-year-old fitness model and author showed her enviable figure in a nude-coloured crochet net swimsuit at The Standard resort in South Beach. The swimsuit model became a fitness icon when she shed an impressive 70lbs and was crowned Miss Bikini America 2006 after famously beating her battle with the bulge. Jennifer weighed 170lbs when she got married, and continued to pile on the pounds during both of her pregnancies, eventually reaching 200 pounds after the birth of her second child. Jennifer launched her own JNL Fusion Gym in New York earlier this year, added that she maintains her incredible rock hard figure by following the diet and workout plan she herself devised. Very impressive!
