Racking and unracking exercise machine
An indication is received from a user to rack or unrack a digital weight. A motor is signaled to apply or remove tension to a cable couple to the motor based at least in part on the indication. The actuator is connected to the cable and is physically arranged to deliver a force to the user. The motor selectively tensions a cable in accordance with an exercise program.
1. An exercise device comprising:
a resistance unit comprising a motor;
a cable coupled to the motor, wherein the motor selectively tensions the cable in accordance with an exercise program; and
an actuator connected to the cable, wherein the actuator is physically arranged to deliver a force to a user, and wherein tension to the cable is applied or removed in response to an indication to rack or unrack a digital weight;
wherein in response to an indication to unrack the digital weight, tension is applied at a first ramp rate for a first interval of time and at a second ramp rate for a second interval of time.
2. The exercise device of claim 1 , wherein the actuator comprises a smart accessory wirelessly connected to the resistance unit.
3. The exercise device of claim 1 , wherein the actuator comprises a Bluetooth smart accessory wirelessly connected to the resistance unit.
4. The exercise device of claim 1 , wherein the actuator includes a control comprising a button.
5. The exercise device of claim 1 , further comprising a voice control to rack or unrack the digital weight.
6. The exercise device of claim 1 , wherein a nominal tension is applied when the digital weight is unracked.
7. The exercise device of claim 1 , wherein in response to the indication to unrack the digital weight, tension is changed first gradually, then more quicky, and then less quickly to reach a desired tension.
8. The exercise device of claim 1 , wherein an amount of jerk when the digital weight is unracked is limited.
9. The exercise device of claim 1 , wherein the indication to unrack the digital weight comprises a user generated command.
10. The exercise device of claim 9 , wherein a remote coaching unit also sends rack and unrack commands in addition to user generated commands.
11. The exercise device of claim 1 , further comprising an audible signal indicating that the digital weight has been unracked.
12. The exercise device of claim 1 , further comprising an audible signal indicating that the digital weight has been racked.
13. The exercise device of claim 1 , further comprising a haptic cue that the digital weight has been racked.
14. The exercise device of claim 1 , further comprising a haptic cue that the digital weight has been unracked.
15. The exercise device of claim 1 , wherein when a nonstandard orientation of the actuator is detected, the digital weight is racked in response.
16. The exercise device of claim 1 , wherein the actuator comprises a heart rate sensor to detect heart rate.
17. The exercise device of claim 1 , wherein the actuator comprises a grip sensor to detect grip.
18. The exercise device of claim 1 , wherein the tension is applied according to a profile determined based at least in part on a type of movement to be performed.
19. A method, comprising:
receiving an indication to rack or unrack a digital weight; and
signaling a resistance unit comprising a motor to apply or remove tension to a cable coupled to the motor based at least in part on the indication to rack or unrack the digital weight, wherein in response to an indication to unrack the digital weight, tension is applied at a first ramp rate for a first interval of time and at a second ramp rate for a second interval of time;
wherein an actuator is connected to the cable and is physically arranged to deliver a force to a user; and
wherein the motor selectively tensions the cable in accordance with an exercise program.
20. The method of claim 19 , wherein the actuator comprises a smart accessory wirelessly connected to the resistance unit.
