ABSTRACT:
A martial arts practicing device with reactive limbs comprises a trunk having a padded front trunk section, and a box-like rear trunk section, together with a plurality of reactive limbs which limbs strike at the location of the practitioner of martial arts in reaction to the practitioner striking the front trunk section. The rear trunk section contains a plurality of springs biased against a rigid board member separating the front trunk section from the spring members. Reactive limbs comprise rigid members biased against the board member by spring hinges with flexible limb members attached to the rigid members. The spring hinges together with rigid biasing members cause the rigid limb members to rotate in response to movement of the board member thereby projecting the ends of the connected flexible limb members into a target area immediately in front of the trunk, which target area is the location of the practitioner. The rear trunk section springs return the padded trunk section to its normally biased position after the strike thereby causing the reactive limb to retract from the target area. Adjusting members are provided to adjust the reaction of the reactive limbs.
