Will Smith poses at the 'Bad Boys For Life' launching photocall in Paris on Jan. 6, 2020.

Will Smith showed "the body that carried me through an entire pandemic" on Instagram, encouraging A-listers like Dr. Dre to do the same as motivation to get back in shape.

The award-winning actor-rapper shared a photo flaunting his dad bod on Instagram earlier this month, declaring in the caption: "I'm in the worst shape of my life." Smith plans to take his fans along on his personal fitness journey in a new six-part unscripted series with YouTube Originals and Westbrook Media tentatively titled Best Shape of My Life, which is set to premiere in 2o22.

But when people followed Smith's lead by showing off their quarantine bods on Instagram, he instructed them, "After pics due in 12 weeks!" as part of the new #BigWillieChallenge. Dr. Dre captioned a mirror selfie of himself lifting up his white T-shirt, "This is my COVID body. I’m about to start getting my sh-- together." The 56-year-old producer suffered a brain aneurysm in January and praised "the excellent care from my medical team" at Cedars-Sinai Medical Center in Los Angeles before returning home a couple of weeks after his hospitalization.

Anthony Anderson mirorred Smith's power pose while wearing only his underwear when he accepted the challenge, while Marlon Wayans wrote, "F--- it! Wait a month... gonna post my transformation by my bday. I’ll have the best body of my life 7/23/2021 stay tuned."
