The ultimate solution for barbell standing calf raises in your home gym.

ucups for barbell standing calf raises 5/8"

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 your calf raises.

Build calf muscle faster

Research shows free-weight exercises require greater muscle fiber recruitment to stabilize the load. U-Cups™ are rated at 1000 lbs and will challenge your calves more than a machine ever could.

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 most common sized rack posts with pin holes. The inside “cup” is 38MM wide which supports most barbell sizes.

Best rack attachment!!!

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!!

Calf raises

Finally I can do standing calf raises in my power rack. Don’t have room for a full calf machine.

U-Cups™

I just had my first try at integrating the U-Cups into my workout routine. They’re a game changer for my setup. I’ve tried many alternatives these were by far the simplest and most effective solution!
