The disclosure relates to a method and device for improving the reliability, maintainability, performance and safety of exercise machines. Generally, the improvement includes installing wear resistant devices and frictionless bearings to promote consistent and predictable resistance accompanied by fluidic and sustained machine operation. The improvement further includes installing a shielding mechanism to guard the mechanical components of the exercise machine from environmental contamination and to further enable draining fluids away from vital mechanical parts. The shield also serves as a safe barrier between the users of the machine and its operating electrical and mechanical parts.

DETAILED DESCRIPTION The present invention provides, inter alia, a device and method for extending the useful life of an exercise machine.
The device and method include a dynamic interface means for improving wear resistance, reliability and maintainability of moving parts at initial stress points within the machines.
Further, the improvement includes means for shielding internal mechanisms of the machine and to collect and drain liquids away from said internal mechanisms of the machine.
The dynamic interface means may include an improved pedal arm shaft assembly.
The improved pedal arm shaft assembly may further include an improved pedal arm shaft sleeve and an improved pedal arm shaft.
The improved pedal arm shaft is disposed within a generally coaxial bore, the bore being disposed within the improved pedal arm shaft sleeve.
The dynamic interface means may also include an improved tubular member on each of a left and right pedal arm.
The improved tubular member will include a generally coaxial bore and a plurality of bearings disposed within the bore.
The inner race of each bearing ideally defines an improved bore.
The improved tubular member may further include a sleeve disposed within the bore, the sleeve having a first and second ends.
The first and second ends of each sleeve may be disposed proximate to at least one laterally disposed bearing.
The dynamic interface means may further include an improved chain attachment mechanism.
The improved chain attachment mechanism may further include an improved bushing and an improved sleeve disposed with the bushing.
The improved bushing and the improved sleeve may be impregnated/flooded with a lubricating substance.
The dynamic interface means may also include left and right leveling arms, each leveling arm with a tubular member, each tubular member with at least one bearing.
The inner race of each bearing defines an improved bore.
The dynamic interface means may further include improved left and right pedals, each improved pedal having a horizontal member and a vertical member
