Product Description

About This Design

A medieval knight in full plate armor — rendered in meticulous vintage engraving detail, every rivet and pauldron accounted for — is deep in the hole, bar loaded, executing a back squat with the focus of someone who has sworn a sacred oath to the squat rack. Surrounding the scene, blackletter Old English text frames the moment as divine law: 'Thou Shalt Not Skip Leg Day.' The commandment has been handed down. Thou hast been warned.

Why You'll Love This Shirt

The double-take happens in stages — first they clock the medieval knight armor, then they read the commandment. That is the whole shirt. Comfort Colors 1717 heavyweight cotton means it's soft enough to wear to every single leg day, which, unlike some people, you never skip.

Perfect For

The perfect white elephant drop at the gym or CrossFit box, a naughty birthday for the squat-obsessed person in your life, or a thank-you for the personal trainer or coach who has been preaching leg day gospel all year. Also deeply correct as a gag gift for the friend who unironically skips leg day every week — consider it a medieval intervention.
