The Rock Rattles the Chains for 'Ballers' Season 2

Dwayne Johnson is hard at work, prepping his physique for his HBO show.

Everyone knows the old saying: you only get out what you put in. Dwayne Johnson's acting chops, promotion skills, and gym work got him a second season of Ballers, his popular HBO show. Judging by his workout post last weekend, he hasn't forgotten his formula for success. His Instagram callout was simple: "Move the chains."

Filming for Ballers kicks off in four weeks, although HBO has yet to release the official premiere date for the next season. We're sure Johnson will be the first to let us know the details-- probably along with more intense training videos.
