XCO® Trainer

Product Description

The XCO® Trainer is a new concept to the world of sport, fitness and rehabilitation. Power and dynamics combine with an excellent extreme workout for stomach, back, shoulder muscles and collagenic connective tissue. The dynamic forward and backward movement of the person holding, will shake the loose mass contained inside the XCO trainer quite violently from one side to the other. This movement works both the agonistic and antagonistic muscle groups e.g. biceps (bend arms) and triceps (stretch arms). This co-contraction of muscles protects the joints. The secret of XCO trainers lies in the fact that inside the bar there is no dead weight, like with dumbbells for instance, but a loose moving mass. This loose mass reaches the holder at the end in a delayed manner, which signals to the muscles to produce a certain initial tension. The reactive impact is the decisive criterion for training with the XCo trainer.
