Mobile fitness system

Abstract

The present application is directed to a mobile fitness system capable of being mounted to a vehicle rack. Components of the fitness system may be adjustably attached to the rack, providing for various free-hanging exercises, as well as allowing for attachment of various other fitness equipment. The fitness system may comprise extensions allowing groups of users to train simultaneously around the vehicle. The fitness system may also comprise a simulated door frame for attachment to a vehicle rack for supporting various home gym equipment that typically mounts to household doors. The fitness system may also comprise a spiral or semi-circular apparatus for performing body weight exercises at a plurality of angles. A plurality of hand grips may be attached to the apparatus, allowing a user to perform a variety of exercises at predetermined angles. The apparatus may be fixed to a vehicle rack to provide a portable training system.

 an upright including the first joint, and 
 a mounting plate attached to said upright, the mounting plate comprising at least one hole for attachment of the mobile fitness system to the vehicle accessory rack via a fastener. 
   
     
     
         9 . The mobile fitness system of  claim 8 , comprising at least two legs extending laterally at symmetrical angles from the extension rail to form an A-frame. 
     
     
         10 . The mobile fitness system of  claim 8 , further comprising at least one extension leg removably attached to each leg. 
     
     
         11 . The mobile fitness system of  claim 8 , further comprising at least one foot attached to a corresponding leg, each foot comprising a plate fixed to each leg or a corresponding extension leg at an angle equal to an angle between said leg or extension leg and a line perpendicular to the ground. 
     
     
         12 . The mobile fitness system of  claim 8 , wherein the first joint allows for one rotational degree of freedom at most. 
     
     
         13 . The mobile fitness system of  claim 8 , wherein the first joint allows for one translational degree of freedom at most. 
     
     
         14 . The mobile fitness system of  claim 8 , further comprising a semi-circular fitness apparatus attached to the extension rail, the semi-circular fitness apparatus comprising at least two semi-circular rims, joined by a plurality of cross bars. 
     
     
         15 . The mobile fitness system of  claim 14 , wherein the semi-circular fitness apparatus further comprises at least one pair of grips attached at corresponding positions to each rim and extending laterally from said rim, each grip having a circular cross section and diameter for grasping by a user's hand. 
     
     
         16 . The mobile fitness system of  claim 14 , wherein each rim of the semi-circular fitness apparatus has a spiral profile. 
     
     
         17 . The mobile fitness system of  claim 14 , wherein the semi-circular fitness apparatus comprises a mounting plate attached to an upper terminal end of each rim for hooking over the extension rail. 
     
     
         18 . A mobile fitness system for attachment to a vehicle accessory rack and for supporting a fitness apparatus configured for attachment to a door, comprising:
