Diabolical Work - Tee

Whoever programmed these belongs down here. The Diabolical Work tee from Conquering Barbell features a horned goat demon grinding out Bulgarian split squats with a dumbbell in each hand, rear hoof up on a burning bench, while a small red imp sits by with a towel and watches. DIABOLICAL WORK runs top and bottom in red lettering with a gold shadow, with CONQUERING BARBELL and CONQUER THE WEIGHTS below. Printed large across the front for lifters who do the accessory work everyone else skips.

Made on a 60/40 cotton/polyester blend for the right balance of softness and structure. Pre-shrunk and lightweight so it holds up through hard training and looks sharp long after the session is over.

  • 60% cotton / 40% polyester blend, soft feel with lasting shape
  • Moisture-wicking and lightweight for high-intensity training
  • Pre-shrunk fabric for a consistent fit after every wash
  • Large full-color front graphic with premium print quality
  • Classic unisex crew neck and short-sleeve cut
  • Printed to order in-house in Tennessee
  • Available in Black and Navy

Every order is printed after you place it. Tees, tanks and hoodies ship in 7–10 business days (after the payment clears). Flags ship in 10–14 business days (after the payment clears). 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.

  • Rich M. deadlifting in the Brutal Lifts tank

    “The perfect pump cover.”

    The relaxed fit one I got recently is the perfect pump cover/extra layer for me. In Alaska the gym can feel cool at times and I hate being cold when I train. Mississippi boy. I just order 3 more. CB versus erbody

    “Walks the walk.”

    THE BEST brand on the market hands down. Walks the walk and talks the talk. Amazing art work and design too. Fits perfectly and just like the guy above saying they abuse the shirts in the gym, same lol.

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.

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.

    Stephen G.Pen Argyl, PA

  • “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

    Azad K.

  • “Went above and beyond.”

    Great product. Customer service went above and beyond to accommodate my requests. Shipping was fast and packaged in a very secure manner so my shirts arrived undamaged. A++++++

One-man operation

Designed, printed and packed by a lifter.

I’m Audie. I compete in powerlifting, and I’ve run Conquering Barbell out of Tennessee since 2013. I design it, print it and ship it. Every shirt is printed in-house after you order. No print farm, no middlemen. If something’s wrong with your order, you’re emailing the guy who made it.

The bar bends. You don’t.
