To provide a training tool using connectors that can be compactly stored and provide training combining conventional ladder training and mini hurdle training.

A gate portion 4 in the shape of a gate in a front view and a support portion 6 supporting the gate portion 4 in a standing state are formed by combining the connectors 1 in the shape of a block having a plurality of insertion holes 3 facing in different directions and bars 2 that can be inserted into the insertion holes 3 of the connectors 1 and connectors 1B are arranged at least in the intersections between the support portions 6 and the gate portion 4, and the connector 1 is so structured as to continuously arrange the gate portions 4 to ensure that a square partitioned off by the gate portion 4 continue, bending in the shape of stairs in a plane view.
