Bulking Squirrel Shirt – I’m Not Fat I’m Bulking Gym Tee

A funny gym animal shirt featuring a determined bulking squirrel and classic fitness humor. Cute, relatable, and workout-approved.

I’m not fat.
I’m bulking.

And the squirrel agrees.

This gym humor shirt pairs classic bodybuilding logic with the most industrious little mass-gainer in nature. Squirrels spend their entire existence gathering, storing, and aggressively preparing for winter — which is basically just off-season training with acorns.

The joke lands instantly for anyone familiar with fitness culture: the eternal justification phase where extra fluff is clearly strategic. The animal angle softens the humor into something playful and self-aware rather than harsh, making it relatable for lifters at any stage.

Bulking season.
But make it woodland.
