How can you increase mmy cheeks without gaining weight?

Answer 1

One of the easiest ways (although it may sound odd) would be learning to play the Trumpet or Trombone. Trumpet or trombone players have to learn to store a lot of air in their cheeks, which results in their size increasing over time. The didgeridoo might also work, however saxophones or flutes will not because they are not supposed to be played using air stored in your cheeks (however they are really good at toning up a double-chin).
