Resistance training device

Abstract

The resistance training device includes a pair of adjustment rails attached to a door frame by at least two mounting blocks. An adjustable exercise platform includes a slidable carriage riding on the adjustment rails to adjustably set the height of the exercise platform. The exercise platform includes a pair of oppositely disposed cavities for receiving resistance blocks. The resistance block provides a predetermined amount of exercise resistance and is interchangeable with other resistance blocks to vary the resistance. A pair of pectoral, butterfly handles are insertably mounted bores in the support block and the resistance block to allow the user to perform butterfly exercises. The resistance training device is easy to assemble/disassemble for storage or transport.

         9 . The resistance training device according to  claim 4 , wherein said movable brace comprises:
 a compressible head to safely brace said anchoring block against the door frame; and   a moving mechanism for moving said compressible head toward the door frame.   
     
     
         10 . The resistance training device according to  claim 9 , wherein said compressible head has notches defined therein, the notches being adapted for conforming to the door frame. 
     
     
         11 . The resistance training device according to  claim 9 , wherein said moving mechanism comprises a wing screw extending through a threaded bore in said base, said compressible head being mounted on a distal end of the wing screw. 
     
     
         12 . The resistance training device according to  claim 2 , wherein said exercise carriage comprises:
 a rectangular body having a pair of spaced bores defined therein for slidably mounting said carriage in a desired position on said adjustment mounting rods, the oppositely disposed cavities being defined in the rectangular body;   a pair of clamps mounted on the adjustment mounting rods below the rectangular body to fix the rectangular body in the desired position;   a spacer brace formed at a rear side of the rectangular body to brace the rectangular body against the door frame; and   a pair of spaced mounting bores for detachably mounting said exercise handles to the rectangular body, each of the cavities being in communication with a respective one of the mounting bores to facilitate operative connection between a respective one of the exercise handles and a respective one of the resistance blocks.   
     
     
         13 . The resistance training device according to  claim 12 , wherein each said resistance block comprises:
 a substantially solid cube having a cylindrical core, the cylindrical core having a partition wall extending diametrically across the core to form semicylindrical hollow through holes, the core being rotatable, the cube being mounted in one of the cavities in said carriage so that the cube does not rotate; and   integral coil springs extending from the cylindrical core into the cube, the springs being biased in one direction, the springs providing the predetermined amount of resistance when the core is rotated against said bias.
