Kelly Brook, who stripped to frilly underwear in a raunchy shoot for Cosmopolitan's Health and Fitness magazine, revealed that her exercising also helped her sex drive.
The 34-year-old model, who donned a naughty blue and spotty white bra and matching knickers for the photoshoot, said that she's always been into dance, yoga and Pilates, but this is totally different.
She said that she's felt incredible for it: so strong and more sexy, the Mirror reported.
Brook asserted that her sex drive went up 100 per cent and that she thinks it's the hormones and testosterone from the weightlifting, adding that she's also been doing ju-jitsu classes and Krav Maga, which was developed for the military in Israel.
