9. The exercise device recited in claim 1 , wherein the target longitudinal force varies with time, and wherein, when executed by the processor, the one or more machine-executable instructions cause the processor to cause the plurality of light sources to emit light in the timed sequence by:

(a) causing a first light source of the plurality of light sources to emit light at a first time to instruct the user to apply a first target longitudinal force at the first time, and

(b) causing a second light source of the plurality of light sources to emit light at a second time to instruct the user to apply a second target longitudinal force at the second time.

10. The exercise device recited in claim 1 , further comprising a display, and wherein, when executed by the processor, the one or more machine-executable instructions further cause the processor to provide workout information through the display, wherein the workout information comprises: an indication of the magnitude of the applied longitudinal force, an indication of an amount of time during which the applied longitudinal force was applied to the exercise device, or an indication of a time under tension.

11. The exercise device recited in claim 1 , further comprising a haptic device coupled to the processor, and wherein, when executed by the processor, the machine-executable instructions further cause the processor to:

(a) cause the haptic device to emit a first vibration to instruct the user to apply the target longitudinal force to the exercise device, or

(b) cause the haptic device to emit a second vibration to provide an indication of the magnitude of the applied longitudinal force relative to the magnitude of the target longitudinal force, or

(c) both (a) and (b).

12. The exercise device recited in claim 1 , further comprising an auditory indicator coupled to the processor, and wherein, when executed by the processor, the machine-executable instructions further cause the processor to:
