The just-released filter depicts a super-sized version of the classic "flexed bicep" emoji inspired by Cena's own famously swole physique. In a series of accompanying new videos, Cena calls on fans to share their biggest flex by using the filter in creative ways—from an amped-up twist on traditional bicep curls to show-stopping power poses—as they tout their greatest achievements. The MET-Rx Flex filter will be available for TikTok users to experiment with throughout the summer, and Cena will personally select and respond to some of the most impressive fan flexes.
