A computerized treadmill is provided. The treadmill deck may be fully suspended by a plurality of air suspension elements, such as bellows. The bellows may be pressurized by a computer-controlled compressor feeding a central air reservoir to which each bellows is connected via air hose. The bellows may be dampened to control expansion. A double hinge connecting the deck with frame may control lateral movement and reduce lateral load on the bellows. Incline and decline mechanisms facilitate a variety of deck angles. Control of the treadmill may be by computer, whether integrated or modular, whether traditional, laptop, tablet or smart phone. Control of the treadmill and conveyance of information associated with treadmill operation may be integrated with computer or smart phone applications, whether dedicated or third party.

1. A treadmill comprising: a rigid treadmill frame, the frame supporting a front roller and rear roller;a flexible belt wrapped around the front roller and the rear roller;a rigid planar treadmill deck interposed between the front and rear rollers, beneath a top portion of the belt; anda plurality of air suspension elements, each air suspension element providing a point of support for the deck, and the plurality of air suspension elements together fully suspending the deck relative to the frame. 2. The treadmill of claim 1, in which one or more of said air suspension elements comprises: an upper fitting secured to the deck;a lower fitting secured to the frame; anda membrane enclosing a volume of air between the upper fitting and the lower fitting. 3. The treadmill of claim 1, in which each of said plurality of air suspension elements is an air bellows having a first end mounted to the treadmill deck, and a second end mounted to the treadmill frame. 4. The treadmill of claim 2, in which one or more of said air suspension elements further comprises a dampening strap interconnecting the upper fitting and the lower fitting, the strap operating to limit movement of the upper and lower fittings away from one another during unloading of the air suspension element. 5. The treadmill of claim 3, in which the plurality of air suspension elements comprises four air bellows and the treadmill deck is rectangular, with one of said air bellows positioned near each corner of the deck. 6. The treadmill of claim 3, in which the plurality of air suspension elements comprises two air bellows positioned near a front portion of the deck, two air bellows positioned near a middle portion of the deck, and two air bellows positioned near a rear portion of the deck. 7. The treadmill of claim 2, in which one or more of said air suspension elements further comprises a damping piston attached to one of said upper or lower fittings, and a receptacle attached to the other of said upper or lower fittings, the piston configured for movement within the receptacle during loading and unloading of the air suspension element. 8. The treadmill of claim 7, in which said receptacle is enclosed and fluid-filled, the piston including a first orifice enabling bi-directional fluid flow between a first side of the piston and a second side of the piston, and check valve enabling unidirectional fluid flow from the first side of the piston to the second side of the piston. 9. The treadmill of claim 1, further comprising a belt drive motor positioned within an area defined by said flexible belt. 10. The treadmill of claim 1, further comprising an incline motor positioned within an area defined by said flexible belt. 11. The treadmill of claim 1, further comprising: an air reservoir;air lines interconnecting one or more of said air suspension elements with said air reservoir; andan electronically-controlled compressor operable to control air pressure within said air reservoir. 12. The treadmill of claim 11, further comprising: an air pressure sensor providing an output indicative of measured air pressure within one or more of the air reservoir and air suspension elements; andin which said electronically-controlled compressor receives one or more control inputs, with at least one of said control inputs being determined based at least in part upon the air pressure sensor output, the compressor utilizing said control inputs to control air pressure within said air reservoir. 13. The treadmill of claim 12, in which at least one of said compressor control inputs is determined based at least in part upon belt speed. 14. The treadmill of claim 12, in which at least one of said compressor control inputs is determined based at least in part upon user impact level. 15. The treadmill of claim 12, in which at least one of said compressor control inputs is determined based at least in part upon a user-controlled configuration setting. 16. The treadmill of claim 1, further comprising a double hinge interconnecting the deck with the treadmill frame. 17. A treadmill comprising: a rigid treadmill frame comprising a right rail and a left rail;incline mechanism slots extending longitudinally within each of the left and right rails;an incline crossbar extending between the left and right rails, the incline crossbar having a right end extending through the right rail incline mechanism slot and a left end extending through the left rail incline mechanism slot;a right incline support bar having a proximal end rotatably connected with the incline crossbar right end and a distal end;a right linkage bar having a proximal end rotatably connected with the right rail at a position forward of the right rail incline mechanism slot, and a distal end rotatably connected with the right incline support bar;a left incline support bar having a proximal end rotatably connected with the incline crossbar left end and a distal end;a left linkage bar having a proximal end rotatably connected with the left rail at a position forward of the left rail incline mechanism slot, and a distal end rotatably connected with the left incline support bar; andan incline motor operating to rotate a lead screw, the lead screw threaded through an incline mechanism control nut secured to the incline crossbar;whereby operation of the incline motor can deploy and retract the left and right incline support bars to increase and decrease the angle of treadmill incline. 18. The treadmill of claim 17, in which each of the left and right incline support bars comprise a wheel rotatably mounted to the distal end thereof. 19. The treadmill of claim 17, further comprising: decline mechanism slots extending longitudinally within each of the left and right rails;a decline crossbar extending between the left and right rails, the decline crossbar having a right end extending through the right rail decline mechanism slot and a left end extending through the left rail decline mechanism slot;a right decline support bar having a proximal end rotatably connected with the right rail and a distal end;a left decline support bar having a proximal end rotatably connected with the left rail and a distal end;a right linkage bar having a proximal end rotatably connected with the decline crossbar right end and a distal end rotatably connected with the right decline support bar between its proximal and distal ends;a left linkage bar having a proximal end rotatably connected with the decline crossbar left end and a distal end rotatably connected with the left decline support bar between its proximal and distal ends; anda decline mechanism control nut secured to the decline crossbar, through which the incline motor lead screw is threaded;whereby the decline support bars are deployed through rotation of the lead screw beyond a position at which the incline support bars are fully retracted. 20.
