Exercise machine with pancake motor

1. An exercise machine comprising:

a frame that includes a front side and a back side;

a first motor and a second motor, wherein a longitudinal axis of the first motor passes through the front side and the back side of the frame, wherein the first motor drives a first cable, wherein the second motor drives a second cable, wherein the first motor is a pancake motor; and

a first slider and a second slider, wherein the first slider is configured to position the first cable at a first plurality of positions, and the second slider is configured to position the second cable at a second plurality of positions.

2. The exercise machine of claim 1 , wherein resistance generated by at least one of the first motor and the second motor is dynamically adjustable.

3. The exercise machine of claim 1 , wherein resistance generated by the at least one of the first motor and the second motor is based at least in part on a target weight.

4. The exercise machine of claim 1 , wherein the first motor is coupled to a first spool, wherein the first cable is wound about the first spool.

5. The exercise machine of claim 4 , wherein the first spool is placed in a lower portion of the exercise machine.

6. The exercise machine of claim 1 , wherein the first motor is placed in a lower portion of the exercise machine.

7. The exercise machine of claim 1 , wherein the first slider positions the first cable on a left side of the frame.

8. The exercise machine of claim 7 , wherein the second slider positions the second cable on a right side of the frame.

9. The exercise machine of claim 1 , further comprising a processor configured to determine a first length associated with the first cable.

10. The exercise machine of claim 9 , wherein the processor is configured to determine the first length associated with the first cable based on a change in cable length from a first position of the first plurality of positions to a second position of the first plurality of positions.

11. The exercise machine of claim 10 , wherein the change in cable length from the first position to the second position is based on a first output of a first sensor at the first position and a second output of a second sensor at the second position.

12. The exercise machine of claim 1 , wherein the first cable is coupled between the first motor and a first actuator.

13. The exercise machine of claim 12 , wherein the first actuator comprises a handle.

14. The exercise machine of claim 1 , wherein a retractable pin is configured to lock the first slider at a first position of the first plurality of positions.

15. The exercise machine of claim 1 , further comprising wherein the first motor is located within the frame, wherein the first slider is located at a first side of the frame and the second slider is located at a second side of the frame, wherein the first side and the second side are opposite sides of the frame.

16. The exercise machine of claim 1 , wherein the first cable and the second cable are coupled to corresponding opposite ends of a bar.

17. The exercise machine of claim 1 , wherein the first cable is capable of being coupled to a strap.

18. The exercise machine of claim 1 , wherein the first motor is configured to provide dynamic resistance.

19. The exercise machine of claim 1 , wherein the first motor is configured to provide a nominal tension of resistance at a first cable zero point.

20. The exercise machine of claim 1 , wherein the first motor provides a first constant tension when the first cable is moving at a first speed and the second motor provides the first constant tension when the second cable is moving at a second speed that is different that the first speed.
