A treadmill may comprise a drive motor positioned and configured to drive a treadbelt, and an electrical current sensor configured to measure the electrical current utilized by the drive motor. The treadmill may also include a computer programmed and configured to analyze the measured electrical current usage by the drive motor to determine the weight of a person positioned on the treadbelt. A person's weight may be determined by driving the treadbelt with the drive motor while a person is positioned on the treadbelt, measuring an electric current utilized by the drive motor, and analyzing the measured electric current to determine the weight of the person positioned on the treadbelt of the treadmill. Additionally, the measured weight may be utilized to calculate calorie expenditure.

1. A method of determining a person's weight, the method comprising: driving, by a drive motor, a treadbelt of a treadmill while a person is exercising on the treadbelt;measuring, by a sensor, an electric current utilized by the drive motor over a period of time that the person exercises on the trea
1. A method of determining a person's weight, the method comprising: driving, by a drive motor, a treadbelt of a treadmill while a person is exercising on the treadbelt;measuring, by a sensor, an electric current utilized by the drive motor over a period of time that the person exercises on the treadbelt as the treadbelt is driven by the drive motor;changing a slope of the treadbelt while measuring the electric current utilized by the drive motor;analyzing, by a computer, the measured electric current; anddetermining, by the computer and based on the analysis of the measured electric current, a weight value that is the weight of the person positioned on the treadbelt of the treadmill. 2. The method of claim 1, wherein analyzing the measured electric current further comprises: analyzing an average measured electric current over the period of time that the person exercises on the treadbelt. 3. The method of claim 2, further comprising determining a cadence of the person positioned on the treadbelt. 4. The method of claim 3, wherein analyzing an average measured electric current comprises: analyzing an average measured electric current corresponding to the determined cadence. 5. The method of claim 1, further comprising positioning the treadbelt to simulate a declining slope. 6. The method of claim 1, further comprising positioning the treadbelt to simulate an inclining slope. 7. The method of claim 1, wherein determining a weight value of the person comprises: comparing, by the computer, the measured electric current to a value on a lookup table. 8. The method of claim 1, wherein determining a weight value of the person comprises inputting the measured electric current into a mathematical function. 9. The method of claim 1, wherein driving the treadbelt of the treadmill with the drive motor while the person is positioned on the treadbelt comprises driving the treadbelt at a linear speed less than about 2.25 meters per second. 10. A method of calculating calories expended by a person while exercising on a treadmill, the method comprising: driving, by a drive motor, a treadbelt of the treadmill while the person is positioned on the treadbelt;positioning the treadbelt to simulate a declining slope;measuring, by a sensor, an electric current utilized by the drive motor over a period of time that the person exercises on a treadbelt of the treadmill while the treadbelt is driven by the motor;changing the slope of the treadbelt while measuring the electric current utilized by the drive motor;analyzing, by a computer, the measured electric current;determining, by the computer and based on the analysis of the measure electric current, a weight of the person positioned on the treadbelt of the treadmill; andcalculating, by the computer, calorie expenditure using the determined weight of the person. 11. The method of claim 10, wherein analyzing the measured electric current further comprises: analyzing an average measured electric current over the period of time that the person exercises on the treadbelt. 12. The method of claim 11, further comprising determining a cadence of the person positioned on the treadbelt. 13. The method of claim 10, wherein determining a weight of the person comprises comparing the measured electric current to a value on a lookup table. 14. The method of claim 10, wherein determining a weight of the person comprises inputting the measured electric current into a mathematical function. 15. The method of claim 10, wherein driving the treadbelt of the treadmill with the drive motor while the person is positioned on the treadbelt comprises driving the treadbelt at a linear speed less than about 2.25 meters per second.
