Gravity mat

An exercise device, comprising;

• at least one pedestal wherein said at least one pedestal comprises:
• a user support platform capable of sustaining weight from a user, movable by said user, and linearly connected to and supported by a first set of rails such that said user support platform is slidable along said first set of rails;
• wherein said first set of rails is supported by and attached at a connection point at each of a first and second end of each of said first set of rails to a second set of rails such that said user support platform is slidable along said second set of rails;
• wherein said second set of rails is perpendicular to said first set of rails and wherein each of said second set of rails has a first and second end attached to;
• and supported by a base;
• a plurality of individually removable resistance members wherein each of said plurality of individually removable resistance members comprises a first and a second end that attach to respective mounting points on said pedestal in a first and second mounting position wherein:
• in the first mounting position, at least one of said plurality of individually removable resistance members is attached between a mounting point at a centralized point on said platform and a mounting point on either the first or second end of one of said first set of rails and
• in the second mounting position at least one of said plurality of individually removable resistance members is attached between a mounting point near either the first or second end of one of said second set of rails and a centralized mounting point between either end of said one of said first set of rails at the connection point of said first and second set of rails such that resistance is generated when said user slides said user support platform along said first and said second set of rails, and said resistance is directed towards a centralized equilibrium position.
