As always Dwayne ‘The Rock’ Johnson uses Instagram to spread the word on his latest projects and happenings. This time, the mega-star is using the social channel to shed more light on his partnership with Under Armour. Together they created ‘Under Armour: Project Rock,’ which is a “motivational lifestyle brand.”

In his latest Instagram post, Johnson shows off some gear from the new line — a bag called the #GBOAT: The Greatest Bag of all Time.  “Project Rock recognizes that we are all a work in progress, consistently trying to get better and working hard toward our goals. Understanding the grit, grind, and sacrifice, I wanted to find a way where I can embark on a journey with others, to inspire them to constantly chase their greatness no matter the intensity,” says the Ballers star.

To kick off Project Rock the line is releasing two new gym bags — the Range Backpack and Regiment Duffle. The Regiment Duffle can hold gear for when you’re headed straight to the gym from work (sized 19″ x 11″ x 7.5″). As for the Range Backpack, it can hold all your gear, along with a separate compartment for gym shoes. As an added bonus, it has straps so it can be used as a backpack.

The Range Backpack is $99 and the Regiment Duffle is $124. Both are available at Under Armour.
