Low profile portable exercise machine with dual resistance

An exercise device, comprising:

• a) a foot carriage comprising a carriage frame with rotatably mounted wheels and a foot support assembly, encompassing a footrest board with specified width and length for which a lower part engages with the carriage frame, while an upper surface of the footrest board is straddle mounted by a footrest frame, which accommodates a pair of footrest assemblies pivotably mounted with hinges, allowing the footrest assemblies to pivot between a low-profile horizontal position and an upward orientation;
• b) a dual resistance assembly incorporates magnetic and elastic resistance components that can be engaged either concurrently or independently to impede the movement of the foot carriage along a track assembly with a first end and second end;
• and
• c) a cross bar slidably mounted beneath a track assembly to allow for variable inclined positions of the exercise device.
