An apparatus includes a first plastic pipe comprising a first end and a second end. A padding surrounds a portion of the first plastic pipe extending from the first end towards the second end. The padding comprises a material for mitigating injuries during striking. A cover encases the padding. A pipe receiver is joined proximate to the second end for grounding motion of the plastic pipe to a structure. The pipe receiver comprises a bracket operable for joining to the structure, and a collar disposed between the bracket and the pipe for mitigating movement of the pipe within the bracket. A concentrically oriented second plastic pipe and third plastic pipe is disposed within the first plastic pipe proximate the second end for mitigating stress on the first plastic pipe proximate the pipe receiver, wherein a strike to the padding flexes the plastic pipe and the plastic pipe springs back. |
