Abstract

An exercise machine includes a first housing, a central electromagnetic resistance unit, a resistance mechanical interface, and a mechanical expansion portion. The resistance mechanical interface includes a spool and a cable configured to provide a force from the central electromagnetic resistance unit in response to a control interface that receives commands from an exercise actuator. The cable extends out from a first side of the first housing. The mechanical expansion port is configured to link the first housing to a second housing via a mechanical attachment. The mechanical expansion port is located at a second side of the first housing. The second side of the first housing is adjacent to the first side of the first housing.

Claims (24)

1. An exercise machine, comprising:

a first housing;

a central electromagnetic resistance unit;

a resistance mechanical interface comprising a spool and a cable configured to provide a force from the central electromagnetic resistance unit in response to a control interface that receives commands from an exercise actuator, wherein the cable extends out from a first side of the first housing; and

a mechanical expansion port configured to link the first housing to a second housing via a mechanical attachment, wherein the mechanical expansion port is located at a second side of the first housing, wherein the second side of the first housing is adjacent to the first side of the first housing.

2. The exercise machine of claim 1 , wherein the mechanical expansion port comprises a shaft, wherein the first housing is further configured to couple in parallel to at least two other housings via the shaft.

3. The exercise machine of claim 1 , wherein the mechanical expansion portion comprises a shaft wherein the first housing is further configured to couple in series to the second housing via the shaft.

4. The exercise machine of claim 1 , wherein the control interface is further configured to couple in parallel to a second control interface in the second housing.

5. The exercise machine of claim 1 , wherein the control interface is further configured to couple in series to a second control interface in the second housing.

6. The exercise machine of claim 1 , further comprising a monitor interface, wherein the monitor interface is configured to accommodate a standard video connection to a monitor.

7. The exercise machine of claim 6 , wherein the standard video connection is an HDMI connection.

8. The exercise machine of claim 6 , further comprising a monitor mechanical interface to support the monitor.

9. The exercise machine of claim 8 , wherein the monitor mechanical interface is a rotating socket.

10. The exercise machine of claim 8 , wherein the monitor mechanical interface can provide landscape orientation for video viewing and portrait orientation for exercise.

11. The exercise machine of claim 8 , wherein the monitor mechanical interface exposes lateral arms in portrait mode.

12. The exercise machine of claim 8 , wherein the lateral arms support the exercise actuator.

13. The exercise machine of claim 1 , wherein the central electromagnetic resistance unit is a motor.

14. The exercise machine of claim 1 , wherein the central electromagnetic resistance unit is two motors.

15. The exercise machine of claim 1 , wherein the exercise actuator is a cardiovascular exercise actuator.

16. The exercise machine of claim 1 , wherein the exercise actuator is a bike.

17. The exercise machine of claim 1 , wherein the exercise actuator is a bike and associated with a front wheel of the bike.

18. The exercise machine of claim 1 , wherein the exercise actuator is a bike and associated with pedals of the bike.

19. The exercise machine of claim 1 , wherein the exercise actuator is a bar.

20. The exercise machine of claim 1 , wherein the exercise actuator is a cable.
