John Cena reveals how he stays in incredible fighting shape

WWE superstar and actor John Cena is one of the busiest entertainers in the world. With roles in four upcoming movies scheduled for release between now and 2018, Cena doesn’t even have time to work a full-time schedule in WWE. In addition to that, he’s also in high-demand as a host and celebrity spokesperson.

Cena’s latest endorsement deal is with the footwear company Crocs for its “Come As You Are” campaign.
