A treadmill having one or more air springs attached to the underside of the treadmill and one or more wheels on the underside of the treadmill near the back end of the treadmill, to provide increased shock-absorption over conventional treadmills. Other embodiments disclosed herein include treadmills
A treadmill having one or more air springs attached to the underside of the treadmill and one or more wheels on the underside of the treadmill near the back end of the treadmill, to provide increased shock-absorption over conventional treadmills. Other embodiments disclosed herein include treadmills with the above-discussed components as well as one or more air compressors, pressure sensors, and/or weight sensors for adjusting the level of pressure in the one or more air springs, based on the weight of a person using such a treadmill.

1. A shock-absorbing treadmill comprising: a treadmill having length, a front end, a back end, a left side, a right side, and an underside;a first air spring attached to the underside of treadmill at the front end, at the left side;a second air spring attached to the underside of the treadmill at th
1. A shock-absorbing treadmill comprising: a treadmill having length, a front end, a back end, a left side, a right side, and an underside;a first air spring attached to the underside of treadmill at the front end, at the left side;a second air spring attached to the underside of the treadmill at the front end, at the right side;a third air spring attached to the underside of the treadmill approximately one-third of the length from the front end, at the left side;a fourth air spring attached to the underside of the treadmill approximately one-third of the length from the front end, at the right side;a first wheel rotatably connected to the underside of the treadmill at the back end, at the left side;a second wheel rotatably connected to the underside of the treadmill at the back end, at the right side,whereby the treadmill is allowed to travel back and forth slightly as the front end of the treadmill moves up and down with each stride taken by a person exercising on the treadmill;a weight sensor adapted to sense the weight of a person on the treadmill;at least one pressure sensor adapted to sense a pressure within at least one air spring; andmeans for inflating or deflating at least one air spring. 2. The shock-absorbing treadmill of claim 1, wherein the means for inflating or deflating at least one air spring comprises at least one air compressor coupled to the at least one air spring. 3. The shock-absorbing treadmill of claim 2, further comprising a processor connected to a computer memory, wherein said processor is further connected to the weight sensor and an output device adapted to visually or audibly provide information, wherein said computer memory contains processor-executable instructions for: electronically receiving information regarding a weight associated with a person located on the treadmill; anddetermining an optimal pressure for the at least one air spring based on the weight of the person. 4. The shock-absorbing treadmill of claim 3, wherein the computer memory further contains processor-executable instructions for: providing information through the output device regarding the optimal pressure for the at least one air spring. 5. The shock-absorbing treadmill of claim 4, wherein the processor is further connected to the at least one air compressor and the at least one pressure sensor, and the computer memory further includes processor-executable instructions for: detecting, via the at least one pressure sensor, the air pressure in the at least one air spring; andcausing the at least one air compressor to inflate or deflate the at least one air spring until the at least one air spring has the optimal pressure. 6. The shock-absorbing treadmill of claim 4, further comprising a control panel attached to the treadmill and the processor, said control panel providing an interface adapted to allow a person to input a desired pressure in the at least one air spring, and wherein the computer memory further contains processor-executable instructions for: detecting, via the at least one pressure sensor, the air pressure in the at least one air spring; andcausing the at least one air compressor to inflate or deflate the at least one air spring until the pressure in the at least one air spring is equal to the desired pressure. 7. A method for adapting an existing treadmill having a length, a front end, a back end, a left side, a right side, and an underside, to be a shock-absorbing treadmill, the method comprising: attaching a first air spring to the underside of treadmill at the front end, at the left side;attaching a second air spring to the underside of the treadmill at the front end, at the right side;attaching a third air spring to the underside of the treadmill approximately one-third of the length from the front end, at the left side;attaching a fourth air spring to the underside of the treadmill approximately one-third of the length from the front end, at the right side;rotatably connecting a first wheel to the underside of the treadmill at the back end, at the left side; androtatably connecting a second wheel to the underside of the treadmill at the back end, at the right side,whereby the treadmill is allowed to travel back and forth slightly as the front end of the treadmill moves up and down with each stride taken by a person exercising on the treadmill;providing a weight sensor adapted to sense the weight of a person on the treadmill; andproviding at least one pressure sensor adapted to sense a pressure within at least one air spring. 8. A method for using a shock-absorbing treadmill having length, a front end, a back end, a left side, a right side, and an underside; a first air spring attached to the underside of treadmill at the front end, at the left side;a second air spring attached to the underside of the treadmill at the front end, at the right side;a third air spring attached to the underside of the treadmill approximately one-third of the length from the front end, at the left side;a fourth air spring attached to the underside of the treadmill approximately one-third of the length from the front end, at the right side;a first wheel rotatably connected to the underside of the treadmill at the back end, at the left side;a second wheel rotatably connected to the underside of the treadmill at the back end, at the right side;a weight sensor adapted to sense the weight of a person on the treadmill; andat least one pressure sensor adapted to sense a pressure within at least one air spring,the method comprising:standing or exercising on the shock-absorbing treadmill, andinflating or deflating the at least one air spring until the pressure sensed in the at least one air spring is substantially equal to a desired pressure. 9. The method of claim 8 for using a shock-absorbing treadmill, further comprising: determining an optimal pressure for at least one air spring based on the sensed weight of a person who is or will be standing or exercising on the shock-absorbing treadmill;wherein said inflating or deflating the at least one air spring is performed until the pressure in the at least one air spring is substantially equal to the optimal pressure. 10. The method of claim 9 for using a shock-absorbing treadmill, wherein the treadmill further comprises an output device and the step of determining an optimal pressure for the at least one air spring based on the sensed weight of a person who is or will be standing or exercising on the shock-absorbing treadmill comprises: standing on the shock-absorbing treadmill; andreceiving from an output device on the shock absorbing treadmill information regarding the optimal pressure for the at least one air spring. 11. The method of claim 10 for using a shock-absorbing treadmill, wherein the shock-absorbing treadmill further comprises: at least one air compressor coupled to at least one air spring;a processor connected to the at least one air compressor, the at least one pressure sensor; the weight sensor, and a computer memory, wherein said processor is further connected to the weight sensor, wherein said computer memory contains processor-executable instructions for:electronically receiving information regarding a weight associated with a person located on the treadmill;determining an optimal pressure for the at least one air springs based on the weight of the person; anddetecting the air pressure in the at least one air spring; andinflating or deflating the at least one air spring until the at least one air spring has the optimal pressure;and the method further comprises:allowing or authorizing the shock-absorbing treadmill to inflate or deflate the at least one air spring until the pressure in the at least one air spring is substantially equal to the optimal pressure.
