Triphasic ISO Cups

Triphasic ISO Cups were made in collaboration with Cal Dietz of Triphasic Training. They securely hold the barbell in a groove, allowing athletes to perform isometric barbells lifts safely and easily. Triphasic ISO Cups allow the athlete to focus on the isometric contraction and not worry about the barbell moving. Click here to learn more about Overcoming Isometrics from Cal Dietz.
