Method and apparatus for physical fitness training

A physical resistance training device, comprising:

• a pressurizer having an input and an output, said pressurizer increasing the pressure on a fluid after said fluid flows into said input, said high pressure fluid flowing out of the pressurizer's output;
• an interface unit having a fluid flow input and a jet nozzle discharge output such that the interface transfers a rapid reaction force on a user pad associated with said interface unit, said user pad being moveable on three dimensional axes (x-y-z) of direction and having one or more grasping points,
• said interface unit receiving a high pressure fluid at its input from the output of the pressurizer and said high pressure fluid being discharged at the jet nozzle discharge output to produce said rapid reaction force to be controlled by the counterforce exerted on the interface unit user pad;
• said rapid reaction force being generated by the discharge of the high pressure fluid at the jet nozzle discharge output of the interface unit wherein said discharge is variably controllable.

A method of usiug a physical resistance training device comprising the steps of:

• providing an interface unit having a user pad that has one or more grasping points and is moveable along three dimensional (x-y-z) axes of direction, said interface unit having an input and a jet nozzle discharge output,
• pressurizing a fluid with a pressurizer having an input and an output, said input receivng an unpressurized fluid and said output being coupled to the input of the interface unit;
• providing the pressurized fluid to the input of the user pad from the output of the pressurizer;
• discharging the high pressure fluid at the jet nozzle discharge output of the interface unit in a controlled direction and velocity of fluid flow to create a variable rapid reactionary force;
• and
• manipulating the interface unit user pad along multiple axes of direction to control the rapid reactionary force with a related counterforce.
