It further includes detecting speed during a concentric phase. It further includes progressively adjusting weight during the concentric phase based on the detected speed and the nominal weight. The weight is progressively adjusted by controlling a resistance mechanism. ## Claims ### Claim 1 A system, comprising: a motor, wherein a cable is coupled between an actuator and the motor; a processor configured to: receive a set of parameters comprising a nominal weight, an upper weight, and a target speed; determine, based at least in part on the nominal weight and the upper weight, a first rate of weight change, wherein the first rate of weight change comprises an amount of weight to add or reduce per unit time; during a concentric phase of a repetition of a movement, control the motor to progressively adjust an amount of provided resistance according to the first rate of weight change; detect a speed of the cable during the concentric phase of the repetition of the movement; and determine a second rate of weight change, wherein the second rate of weight change is different from the first rate of weight change, and wherein the second rate of weight change is determined based on: a first value comprising a fixed rate of weight change that is based on whether the detected cable speed is above or below the target speed; and a second value that is proportional to a difference between the detected cable speed and the target speed; and a motor controller configured to control motor torque to progressively adjust the amount of provided resistance according to the second rate of weight change. ### Claim 2 (depends on 1) The system of claim 1, wherein the set of parameters is determined based on at least one of historical data associated with a user, and demographic data associated with the user. ### Claim 3 (depends on 1) The system of claim 1, wherein the detected speed is based at least in part on measuring a change in position of the cable over time. ### Claim 4 (depends on 1) The system of claim 1, wherein determining the first rate of weight change is based at least in part on a count of the repetition. ### Claim 5 (depends on 1) The system of claim 1, wherein the processor is further configured to determine an N-rep max comprising an estimated max weight for a set including N amount of repetitions, and wherein N is greater than one. ### Claim 6 (depends on 5) The system of claim 5, wherein the processor is further configured to convert the N-rep max to a one-rep max. ### Claim 7 (depends on 5) The system of claim 5, wherein the N-rep max is used to determine a suggested weight for a subsequent set of the movement. ### Claim 8 (depends on 1) The system of claim 1, wherein the repetition is included in a calibration set. ### Claim 9 (depends on 8) The system of claim 8, wherein the calibration set is included in a workout in response to an indication that a calibration should be performed. ### Claim 10 (depends on 9) The system of claim 9, wherein the calibration set is included in the workout based at least in part on a period of user inactivity. ### Claim 11 (depends on 9) The system of claim 9, wherein the calibration set is included in the workout based at least in part on an injury status of a user. ### Claim 12 A method, comprising: receiving a set of parameters comprising a nominal weight, an upper weight, and a target speed; determining, based at least in part on the nominal weight and the upper weight, a first rate of weight change, wherein the first rate of weight change comprises an amount of weight to add or reduce per unit time;

and a second value that is proportional to a difference between the detected cable speed and the target speed; and controlling, via a motor controller, motor torque to progressively adjust the amount of provided resistance according to the second rate of weight change. ### Claim 13 A computer program product embodied in a non-transitory computer readable medium and comprising computer instructions for: receiving a set of parameters comprising a nominal weight, an upper weight, and a target speed; determining, based at least in part on the nominal weight and the upper weight, a first rate of weight change, wherein the first rate of weight change comprises an amount of weight to add or reduce per unit time;
