About Us

“Anime feeds the soul. Gym builds the body. Anime x Gym”

Onii Gainz is born from the idea of expressing our passions. At the core, we are Anime fans avidly involved in the Anime lifestyle who enjoy staying active and frequenting the gym. To us, the anime community and fitness community are gateways for inspiration, motivation, and belonging. We hope to bring that to you.

 

Our brand is committed to our artists. We believe in giving credit where credit is due and aim to uplift those around us. Artists are our beginning, and we are committed to giving them the stage that they deserve. See our Artists!

 

“The best quality, in a timely manner”

We are based in California, USA and ship our gym-themed anime designs throughout the USA and internationally. We offer various designs and merch types, while actively expanding our selection. Please see our FAQs for more information.

 

We love showing off our passion for Anime and Gym and hope you will too!
