Abstract
A striking device for training in martial arts comprises a base and at least two arc supports of differing heights, resiliently attached in a vertical plane to the base; striking area supported on the concave side of the arc supports; adjustable spacers between the arc supports to provide variable tension levels to the arc supports; and a back brace supporting the convex side of at least one of the arc supports and at a point on the convex side so as to provide maximum stable resistance.
