1. A training device comprising:
a hub comprising an upper side, a lower side, and a plurality of ports;
at least one elastic cord extending from the hub and accessible via at least one of the plurality of ports; and
at least two arms extending from the hub, wherein each of the at least two arms (i) has a proximal end proximate the hub and a distal end distal the hub, (ii) extends along an axis from the hub, (iii) is coupled to the at least one elastic cord, and (iv) is configured to move relative to the hub,
wherein the training device is configured to assume (i) a closed state wherein the at least two arms both extend downwardly from the lower side of the hub and (ii) an open state wherein the at least two arms extend laterally outwardly from the hub between the upper side and the lower side of the hub and in different directions from the hub, and
wherein the at least one elastic cord biases the at least two arms in the open state.
