Abstract

An exercise machine adjustable resistance system and method for efficiently varying the workout resistance for an exercise machine. The exercise machine adjustable resistance system and method generally includes a control unit in communication with a resistance adjustment system of an exercise machine and a biometric monitoring device used by an exerciser on the exercise machine. The control unit receives biometric data from the biometric monitoring device and sends a control signal to the resistance adjustment system to adjust the resistance of the exercise machine based on the biometric data received.

First claim

The invention claimed is:

1. An exercise machine having an adjustable resistance system, comprising:
an exercise machine having a frame, a carriage movable upon said frame and a resistance device connected to said carriage, wherein said carriage is movable between a first end and a second end of said exercise machine along a longitudinal axis and wherein said resistance device provides a level of resistance to said carriage along at least a first direction of movement of said carriage;
a biometric monitoring device connected to an exerciser, wherein said biometric monitoring device monitors at least one biometric state of said exerciser; and
a control unit in communication with said resistance device of said exercise machine and said biometric monitoring device, wherein said control unit receives biometric data from said biometric monitoring device relating to said at least one biometric state of said exerciser and wherein said control unit sends a control signal to the resistance adjustment system to adjust said resistance level of said exercise machine based on said biometric data received; wherein said resistance device is comprised of a plurality of springs that are selectively connectable to said carriage, wherein said resistance device increases a number of said plurality of springs of said resistance device that are connected to said carriage when said control unit signals an increase in said resistance level and wherein said resistance device decreases a number of said plurality of springs of said resistance device that are connected to said carriage when said control unit signals a decrease in said resistance level.

2. The exercise machine of claim 1 , wherein said exercise machine is comprised of a Pilates machine.

3. The exercise machine of claim 1 , wherein said biometric monitoring device is comprised of a heart rate monitor that measures a heart rate of an exerciser.

4. The exercise machine of claim 1 , wherein said control unit automatically changes said resistance level of said resistance device in real-time throughout the exercise routine to achieve a desired biometric state of said exerciser.

5. The exercise machine of claim 4 , wherein said desired biometric state is comprised of a desired percentage of a maximum heartrate for said exerciser.

6. The exercise machine of claim 5 , wherein said control unit increases said resistance level of said resistance device if a current heartrate of said exerciser is below said desired percentage of said maximum heartrate for said exerciser.

7. The exercise machine of claim 6 , wherein said control unit decreases said resistance level of said resistance device if a current heartrate of said exerciser is above said desired percentage of said maximum heartrate for said exerciser.

8. The exercise machine of claim 1 , wherein said carriage includes a spring assembly latch that is alignable with respect to an idle spring carrier of said resistance device, wherein said idle spring carrier is connected to a distal portion of a first spring when said first spring is not connected to said carriage, wherein said idle spring carrier is moved by an actuator towards said springs assembly latch and transfers said first spring to said spring assembly latch when said control unit signals to said resistance device to increase said resistance level of said resistance device thereby connecting said first spring to said carriage for increased resistance.

9. The exercise machine of claim 8 , wherein said idle spring carrier removes said first spring from said spring assembly latch when said control unit signals to said resistance device to decrease said resistance level of said resistance device.

10. The exercise machine of claim 1 , wherein said resistance device is comprised of an electromechanical spring latching and unlatching mechanism.

11. The exercise machine of claim 1 , wherein said resistance device is comprised of an eddy current brake.

12. The exercise machine of claim 1 , wherein said resistance device is comprised of a dashpot.

13. The exercise machine of claim 1 , including a resistance input device in communication with said control unit, wherein said exerciser may manually input a desired resistance level for said resistance device via said resistance input device.

14. The exercise machine of claim 1 , including a resistance sensor connected to said resistance device to measure said resistance level, wherein said resistance sensor is in communication with said control unit.

15. The exercise machine of claim 1 , wherein said control unit is in wireless communication with said biometric monitoring device.

16. The exercise machine of claim 1 , wherein said control unit is in wireless communication with said resistance device.

17. An exercise machine having an adjustable resistance system, comprising:
an exercise machine having a frame, a carriage movable upon said frame and a resistance device connected to said carriage, wherein said carriage is movable between a first end and a second end of said exercise machine along a longitudinal axis and wherein said resistance device provides a level of resistance to said carriage along at least a first direction of movement of said carriage;
wherein said exercise machine is comprised of a Pilates machine;
a biometric monitoring device connected to an exerciser, wherein said biometric monitoring device monitors at least one biometric state of said exerciser and wherein said biometric monitoring device is comprised of a heart rate monitor that measures a heart rate of an exerciser;
a control unit in communication with said resistance device of said exercise machine and said biometric monitoring device;
wherein said control unit receives biometric data from said biometric monitoring device relating to said at least one biometric state of said exerciser,
wherein said control unit sends a control signal to the resistance adjustment system to adjust said resistance level of said exercise machine based on said biometric data received;
wherein said control unit automatically changes said resistance level of said resistance device in real-time throughout the exercise routine to achieve a desired biometric state of said exerciser;
wherein said desired biometric state is comprised of a desired percentage of a maximum heartrate for said exerciser;
wherein said control unit increases said resistance level of said resistance device if a current heartrate of said exerciser is below said desired percentage of said maximum heartrate for said exerciser and wherein said control unit decreases said resistance level of said resistance device if a current heartrate of said exerciser is above said desired percentage of said maximum heartrate for said exerciser;
wherein said resistance device is comprised of a plurality of springs that are selectively connectable to said carriage, wherein said resistance device increases a number of said plurality of springs of said resistance device that are connected to said carriage when said control unit signals an increase in said resistance level and wherein said resistance device decreases a number of said plurality of springs of said resistance device that are connected to said carriage when said control unit signals a decrease in said resistance level; and
a resistance sensor connected to said resistance device to measure said resistance level, wherein said resistance sensor is in communication with said control unit to provide data relating to said resistance level of said resistance device to said control unit.
