An exercise machine having a rolling platform and adjustable bar members. The platform is supported on frame rails, and is biased by springs towards an end of the machine. The rails have a rectangular cross-section angled 45° to horizontal, and roller assemblies on the platform include wheels angled to engage the surfaces of the rails substantially normal thereto. The adjustable bar assemblies include upwardly extending bars having upper members that are rotatable about a generally vertical axis so that handle portions at the upper ends thereof extend in different direction. At least one of the bar assemblies is also selectively pivotable about a horizontal axis to positions in which it is engaged by a locking assembly on the frame of the machine. The machine enables the user to perform a wide variety of exercises in reclined, prone, seated and standing positions, both on and off the platform.

The exercise machine of claim 10, wherein said rail members each comprise: a downwardly sloped upper surface and an upwardly sloped lower surface converging towards a medial side of said rail member. 12. The exercise machine of claim 11, wherein said downwardly sloped upper surface and upwardly sloped lower surface extend at angles of about 45° to horizontal. 13. The exercise machine of claim 12, wherein said first and second rail members comprise: first and second substantially rectangular tube members mounted so that all sides thereof extend at angles of approximately 45° to horizontal. 14. The exercise machine of claim 11, wherein said roller assemblies on said platform each comprise: at least one upper roller wheel that engages one of said upper sloped surfaces substantially normal thereto; andat least one lower roller wheel that engages one of said lower sloped surfaces substantially normal thereto. 15. The exercise machine of claim 14, wherein said roller assemblies are mounted in outwardly facing pairs on opposite sides of said platform, said pairs of roller assemblies being spaced apart by a distance sufficient that said sloped upper and lower surfaces of said medial sides of said rail members are captured between said upper and lower roller wheels so as to restrict vertical movement of said platform relative to said frame. 16. The exercise machine of claim 10, furthering comprising: a spring yieldingly biasing said platform towards one of said ends of said frame. 17. The exercise machine of claim 16, wherein said spring yieldingly biasing said platform towards one of said ends of said frame comprises: at least one tension spring interconnecting said platform and said frame. 18. An exercise machine comprising: a frame assembly having a head end and a foot end, said frame assembly comprising: first and second parallel, spaced apart rail members having a rectangular cross-section, said rail members being mounted level with one another and with sides extending at angles of approximately 45° to horizontal, so that medially facing sides of said first and second rail members form downwardly sloped upper surfaces and upwardly sloped lower surfaces;a platform assembly located on said rail members, said platform assembly comprising: a generally horizontal platform member;a plurality of roller assemblies that support said platform member on said rail members for movement thereover towards said head end and said foot end of said frame assembly, said roller assemblies each comprising upper and lower roller members that engage said sloped upper and lower surfaces of one of said rail members substantially normal thereto, said roller assemblies being mounted in opposing pairs on said platform member and spaced apart laterally by a distance sufficient that said medially facing sides of said first and second rail members are captured intermediate said opposing pairs of roller assemblies so as to restrict vertical movement of said platform assembly on said frame assembly; andat least one tension spring yieldingly biasing said platform towards said foot end of said frame assembly; andat least one adjustable bar assembly comprising a pair of upright bars mounted on opposite sides of said frame assembly, said upright bars each comprising: a lower bar member extending generally upwardly from said frame assembly;an upper bar member having a grip portion extending generally horizontally so as to be accessible to a user on said platform; anda coupling rotatably connecting said upper bar member to said lower bar member so that said generally horizontal grip portion is selectively rotatable to a plurality of positions for differing exercises performed on said machine, said coupling comprising: a first coupling member mounted to an upper end of said lower bar member;a second coupling member mounted to a lower end of said upper bar member; anda spring yieldingly biasing said first and second coupling members into a locking engagement;so that in response to a user applying force to said upper bar segment against said spring said first and second coupling members are separated from said locking engagement to allow said grip portion to be rotated to a selected position, and in response to a user releasing said upper bar member said first and second coupling members are biased into said locking engagement so as to retain said grip portion in said selected position. 19.
