Abstract: An exercise apparatus includes an elongate cable being elastic and having opposing first and second ends configured to be grasped by a user. The elongate cable is configured to provide resistance to being stretched along its length in response to an application of a tension force to the first and second ends of the cable and return to its unstretched length upon the user releasing the tension force. The elongate cable includes a first portion having a first elasticity, and a second portion having a second elasticity that is different than the first elasticity of the first portion.

Abstract: According to one example, an exercise system includes a base, a vertical housing extending vertically outward from the base, a first weighted touchpoint moveably coupled to the vertical housing, a second weighted touchpoint moveably coupled to the vertical housing, and one or more weight systems configured to provide weight to the weighted touchpoints. The exercise system further includes a control system that determines randomized workouts that include a random selection of a muscle group, a weight amount, a weight differential, a number of sets of an exercise, and/or a number of repetitions in the set. The control system may also cause the weight system to adjust the weight of the weighted touchpoints based on the randomized workout.

The actuator is configured to rotate the spool. The actuation system is configured to extend and retract the distal end of the rollable neck out of the arm. The distal end of the rollable neck is configured to hold a ball.

Abstract: A batting tee system includes a housing, a ball holder for holding a ball, a neck coupled between the housing and the ball holder, an actuator, and a control system. The actuator may be positioned in the housing and operable to actuate the neck along the axis to extend and retract the neck from the housing thereby increasing and decreasing a distance between the ball holder and the housing. The control system may be operable to cause the actuator to actuate the neck to a first random position along the axis. The control system may be further operable to cause the actuator to actuate the neck to a second random position along the axis, different than the first, after a ball is hit from the ball holder when the neck is in the first position.
