Gainzilla

The largest, strongest, dinogainzorus in the world. It will move weights and buildings easily. It also happens to love to eat those 45 lb steel plates.

We print on unisex fitted-cut tees. If you fall in between two sizes, we recommend buying the larger one. See the sizing chart for more info.

Printed on highest quality, 90% cotton, 10% polyester this shirt is breathable and feels comfortable while training. Printed in the U.S.A.

Every order is printed after you place it. Tees, tanks and hoodies ship in 7–10 business days. Flags ship in 10–14 business days. Weekends and holidays don’t count.

Priority Mail shows at checkout when your order’s weight qualifies. It speeds up delivery, not printing.

To prolong the lifespan of your Conquering Barbell apparel we recommend the following care process.

  • Launder/wash cold with like colors
  • Wash inside out
  • Tumble dry low, or hang dry
  • If desired, steaming can be utilized to remove wrinkles; do not iron.

In their words

  • “Fits the big boys.”

    Really comfortable shirt for the big boys. I got the 3XL (I currently weight 305lbs standing at 6'1") and it fits perfectly. A little breathing room so on and so forth and it hangs lower than your normal tee. If you're about my size and want a tighter fit I would recommend the 2XL. Definitely recommend Conquering Barbell and will be back to purchase more.

  • “Print quality is excellent.”

    Friggin awesome tee. The cotton-poly blend makes for the perfect fit and comfort. And the print quality is excellent. I will buy more tees soon.

    Roman V.Lubbock, TX

  • “Best fitting shirts.”

    I ain’t gonna lie I have so many shirts in my closet I need to give stuff away to make room for more. But this brand makes the best fitting shirts I have bought ever! Great quality too. If you like the tight fit around the arms it’s the best and makes my shoulders look wider. Wear it to the gym or wherever. I’m a size large but I got my shirts in XL and it’s just right. And they have a huge selection Worth the wait

    I ordered a shirt from Conquering Barbell, and the quality is fantastic! The fit makes you look jacked, and the fabric is super comfortable. I had a shipping problem (not their fault), and Audie took care of me right away. I will for sure be ordering again!!!

The shirt

Built to train in.

A soft, light blend that moves with you and holds its print.

  • 60/40 cotton-poly.

    Soft from the first wear. Navy and Maroon are 100% ring-spun cotton.

  • Athletic unisex fit.

    Runs true to size, XS to 4XL.

  • Printed to order in Tennessee.

    Every shirt is printed in-house. No middlemen, no mass production.

A little help with the fit

Find your fit. Then chase the PR.

Like it snug on the arms? Room to breathe under the bar? Start with a shirt you already love.

  1. 1

    Lay your favorite shirt flat.

    Measure straight across, armpit to armpit. That's the chest width.

  2. 2

    Check the length.

    Measure from the back collar seam straight down to the bottom hem.

  3. 3

    Match it to ours.

    Compare with our garment measurements, or let Find my size do the math.
