For our design we chose not to go for something straight forward. For the design on the back we made it so it's offsets to the left. We've came up with multiple designs but this one stuck with us.
For the text we wanted it to aline with the brand but also give it some nostalgia. This is why we landed on the original cheat code from the game Grand Theft Auto San Andreas. In the game you needed to go to the gym to make 'CJ', (the character in the game) gain muscle. So as reference to the game and to gaining muscle we dedicated the back design to the game.
