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 allows you to focus 100% on your mind-muscle connection until failure.

Build calf muscle faster
Research shows free-weight exercises require greater muscle fiber recruitment to stabilize the load. Rated to handle over 1000 lbs, using U-Cups® will challenge your calves in a whole new way.

Save space in your home gym
Dedicated standing calf machines and Smith machines can take up valuable floor space in your gym. U-Cups® let you save that space (and money) by utilizing your existing rack and barbell.

Compatible with most racks and barbells
U-Cups® are designed to fit common sized rack posts with 1" or 5/8" pin holes. The "U chamber” is 35mm deep, supporting most barbell diameters, and is 11" in height to allow safe, full range of motion calf raises.

Lifetime Guarantee
U-Cups® are solid, made with the highest grade of steel (A36 carbon plate) and HDPE (UHMW available on request) plastic inserts. There are no moving parts. Their overbuilt quality will withstand whatever 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.
