1. An exercise machine, comprising:
a frame having at least one rail;
a movable platform moveably connected to the at least one rail and adapted to be moveable along at least a portion of the at least one rail;
at least one biasing member adapted to be removably connected to the movable platform;
a stationary end platform connected to the frame and positioned near a first end of the frame; and
a travel limit decelerator, the travel limit decelerator is adapted to engage the movable platform as the movable platform approaches the stationary end platform, wherein the travel limit decelerator is adapted to smoothly and gently decelerate the movable platform when the movable platform approaches the stationary end platform so that the movable platform is brought to a smooth, gentle, non-damaging stop;
wherein the travel limit decelerator comprises a shaft and a bias device connected to the shaft, wherein the bias device is adapted to provide a bias force to the shaft to smoothly and gently decelerate the movable platform to the smooth, gentle, non-damaging stop, and wherein the bias device is comprised of a spring or a fluid displacement device.
