<p>An implement for training the recti abdominis muscles, concentrating thereon workload while preventing the workload from being distributed to the antagonists, such as the iliopsoas muscles; it is constituted, for example, by a frame (31) with three sides: a front one (33), for resting the hands, and two lateral ones, at the rear ends of which an elastic band (1) is anchored and acts as a fourth side; the elastic band is adapted to activate a contrast (RE) in the exercise that consists in flexing the trunk forwards and rotating the pelvis backwards, keeping substantially constant the position of the axis AC that joins the coxofemoral articulation to the scapulohumeral articulation; the implement is used to stimulate equilibrium between the pelvis and the spine, in gymnasiums or even at home, particularly for sports training. <IMAGE></p> |
