Stay focused on your calves
U-Cups™ were designed to prevent tipping backward while doing standing barbell calf raises. The U-shaped chamber contains the barbell which lets you focus 100% on the mind-muscle connection.
Build calf muscle faster
Research shows free-weight exercises require greater muscle fiber recruitment to stabilize the load. Rated at 1000 lbs, U-Cups™ will challenge your calves more than any machine can.
Save space in your gym
Standing calf machines and Smith machines can take up valuable floor space in your gym. U-Cups™ let you save space (and money) by utilizing your existing rack.
Works with most racks and barbells
U-Cups™ are designed to fit common sized rack posts with 1" or 5/8" pin holes. The inside “cup” is 38mm deep and will fit most barbell sizes, and is 11" in height to allow a full range of motion.
Lifetime Guarantee
U-Cups™ are solid, made with the highest grade of steel (A36 carbon plate) and HDPE plastic inserts. There are no moving parts. Their overbuilt quality will withstand whatever abuse you throw at them and still last a lifetime.
Made in the USA
U-Cups™ are utility patent protected (U.S. Patent No. 11,890,498) 100% American made. From source materials to manufacturing, assembly, packaging and shipping. We believe in supporting local economies.

I ordered the wrong size and they helped me out immediately!! Great company!
Our pleasure, Justin, thanks again!
I have used these 3 times since I got them a week and a half ago, and am already in love with them. The added stability when lifting heavy is a total game changer, as I can challenge my calves with way more weight than before. Before getting these, I could never perform heavy barbell calf lifts on a wedge without fear that I'd lose my balance when trying to go close to failure. Not any more!
I have loaded over 350 lbs on these and they are very sturdy, which gives me total confidence in doing full range of motion barbell calf raises, with 100% safety. I can now go to failure, which is critical for calves. The U-Cups are HEAVY duty but still compact, saving me precious space in my garage. I ordered the 3x3 size and am using the 2x2 adapter, which work perfectly. I'm glad I took the gamble and bought these, they are the exact solution I was looking for.
What a stellar review, wow. Made our day. Thank you, Tim!!
IF ANY GYM DOES NOT HAVE THIS IT IS NOT COMPLETE. IT IS PERFECT. 100% QUALITY PRODUCT. THERE IS NOTHING TO BE IMPROVED ABOUT IT.AND IT IS NOT JUST FOR CALVES TRAINING.BARBELL STORAGE, HOLD TO SET UP A LOAD. SAFER THAN ANY J-CUP.
Awesome! We couldn't agree more (although we're obviously biased 😄). Thank you for sharing, Marcus!
I'm 6'1 and this works great with my Titan x3 flat foot short and homemade calf block. So much better than using sandwich j cups or trying to balance, and I can finally get full range of motion! If you're 6'4 or taller than you will need a taller rack or have to bend your knees some because the x3 flat foot short doesn't have any higher up holes to use.
Tip - these are buttery smooth if you use them with a bar with no knurling towards the end, like the Rep Fitness PowerSpeed Bar.
Picture comparing the size to the titan x3 sandwich j cups
So appreciate you sharing your review, Mike! Glad they work with the X-3 and your height. Good to know about Rep's speed bar too.
Regarding the smooth factor, there's also a way to avoid rubbing (or gliding) against the plastic pads altogether, as well as recruit a bit more calf stabilizing muscles. You have to find the right foot placement under the bar as shown in this video: https://www.youtube.com/watch?v=a3pc5OwR8YI (at 2:52). Once you get it right, you should only experience tapping-feedback at most (versus scraping or rubbing through reps). Thanks again!
Since getting my U-cups I’m able to successfully perform calf raises with heavy weight and not sacrifice form. Has the same feel as using a smith machine. This is an excellent home gym rack attachment. It's well worth the money!!
Fantastic to read, Michael! Brings back memories of when we loaded up 495 on our first prototype. Repped out without issue. Thank you for sharing!
