The so-called “XCO Trainer” is a 26-centimeter-long aluminum tube, two-thirds of which is filled with loose slate granules that move with a time delay when the tube is in motion. This creates a reactive effect—the XCO effect occurs. This means that there is a delayed impact of the loose material against the end caps. This directly leads to the first advantage: Training with XCOs is particularly gentle on the joints, as it creates a certain amount of baseline tension in the muscles.
