OK! Exclusive: Inside Gigi Hadid And Zayn Malik’s Sexy Martial Arts Workouts!

Gigi Hadid and Zayn Malik have started martial arts lessons together – and the supermodel has been boasting to friends that it’s totally spiced up their sex life!

“They love it," an insider close to the couple exclusively revealed to OK! "They have a mixed martial arts expert come to the house twice a week and they’ve been practicing sparring at home." 

"The hilarious thing is that they’ve since turned into a pair of wrestling siblings," the source said, "and Gigi says the best part is how things always end up getting sexy between them when they practice alone."

This new NSFW marital arts routine has not only improved the couple's love life, but also their physiques. "They’ve both noticed a new tone to their bodies and plan on keeping it up," the source said.

This isn't the first time the pair is showing off their athletic skills. Their steamy photoshoot for Vogue last year demonstrated their acrobatic abilities.
