The legendary Rams defensive lineman Aaron Donald is an NFL superstar as well as an businessman.

Donald owns Ready Nutrition, which just added protein-rich Ready Bars to its line of popular sports hydration drinks.

So Donald and Dwayne The Rock Johnson have a lot to talk about during workout breaks — Johnson has more side businesses than two hands can count.

Donald recently worked out with The Rock, who shouted out Donald as his “brotha in grind,” pairing the syncopated workout video with Nipsey Hussle‘s “Grinding All My Life.”

The Rock said he appreciates Donald’s “work ethic and perspective.”
