Jessica Simpson Flaunts Toned Physique in Instagram Photo

Singer's fitness routine and diet contribute to 100-pound weight loss since 2019

Jessica Simpson, 43, recently posted a photo on Instagram showing off her toned physique in a zebra-print swimsuit from her own fashion line.
Simpson's fitness routine includes walking 14,000 steps a day and three 45-minute gym sessions a week with her trainers Harley Pasternak and Sydney Liebes.
She follows Pasternak's Body Reset Diet, which suggests eating three meals and two snacks per day, and prioritizes getting at least seven hours of sleep per night.
Simpson has lost 100 pounds since the birth of her third child, Birdie, in 2019, a transformation she credits to a visit to a nutritionist and a change in her eating habits.
Simpson's fashion line continues to dominate, and her memoir Open Book is being turned into a scripted Amazon show.
