8. An underwater treadmill system, comprising:

a submergible treadmill portion having a fluid-driven treadmill belt, the treadmill belt including a continuous belt extending around a drive roller at a first end and an idler roller at a second end;

a power source to drive the fluid-driven treadmill belt, the power source being a first hydraulic pump providing a fluid at a constant speed; and

a housing connected to the treadmill portion, the housing including a console;

wherein the housing includes a jet having a nozzle, a direction of a stream of water emanating from the jet nozzle being adjustable in a direction toward a surface of water, in a direction toward a surface of the treadmill belt and included angles there between; and

a proportional valve, wherein velocity of the treadmill belt is changed by adjusting the flow of fluid from the first hydraulic pump powering the treadmill belt using the proportional valve.

9. The system of claim 8 wherein the fluid-driven treadmill belt is powered by a first hydraulic motor powered by fluid from the first hydraulic pump that is driven by a single speed alternating current motor in the power range of 1-3 horsepower.

10. The system of claim 9 wherein the first hydraulic motor is driven by the first hydraulic pump, the system further including a proportional valve to adjust an amount of fluid flowing to the first hydraulic motor from the first hydraulic pump, the proportional valve being controlled from the housing.

11. The system of claim 9 wherein the jet is powered by a second hydraulic motor driven by a second hydraulic pump, the system further including a flow control valve to adjust the fluid flowing to the second hydraulic motor from the second hydraulic pump, the flow control valve being controlled from the housing.

12. The system of claim 8 wherein the jet nozzle produces the stream of water, the nozzle powered by an impeller that that is driven by a hydraulic motor.

13. The system of claim 12 further including a conduit, the conduit in fluid communication with the jet nozzle, the conduit extending toward the motor from the housing.

14. The system of claim 13 wherein the conduit includes a single bend of from about 45° to about 135° so that the conduit, hydraulic motor and impeller can provide a flow of water to the jet nozzle, and the conduit, nozzle and hydraulic motor can be positioned within the housing.

15. The system of claim 8 further including means for adding air to the stream of water.

16. The system of claim 15 wherein the means for adding air to the stream of water further includes a blower, the blower being controlled from the housing.

17. An underwater treadmill system, comprising:

a submergible treadmill portion, the treadmill portion including a continuous belt extending around a drive roller at a first end and an idler roller at a second end;

a housing connected to the submergible treadmill portion;

a jet within the housing emanating a stream of water;

a power source to drive the continuous belt of the treadmill portion and the jet;

wherein a direction of the stream emanating from the jet is adjustable in a direction toward a surface of water, in a direction toward a surface of the treadmill belt and included angles there between; and

wherein a first power source drives the treadmill belt and a second power source drives the jet.

18. The underwater treadmill of claim 17 wherein the first power source driving the belt is selected from the group consisting of a hydraulic drive motor, low voltage DC current and self-propulsion by a user.
