ABSTRACT:
Apparatus useful in practicing a karate kick is provided. The apparatus includes a frame, a vertically adjustable platform affixed externally to the frame, a rotatable slide assembly having a forward end and a rear pivot end, the rear pivot end being affixed to the frame adjacent the platform, the slide assembly extending internally within the frame. A foot slide block assembly is slideably engaged in the slide assembly so as to slide from an initial rest position adjacent the rear pivot end to a final fully-extended position adjacent the forward end of the slide assembly. The foot slide block assembly has a resistance mechanism affixed to the slide block which resists movement of the slide block assembly from the initial rest position to the final fully-extended position, whereby, when a user stands on one foot on the platform, suitably adjusted for the user's height and places his other foot on the slide block in the initial position and gives a kick, the slide block slides in the slide assembly to the final position restrained by the resistance means, thereby giving the user exercise for those muscles specifically associated with the kick.
