In the support zone, a front end of a movable step is supported by a front track guide and a rear end of the movable step is supported by a rear track guide. A transition element supports the rear end of the step between the rear guide track and a base guide track, thereby lowering the step-up height of the exercise device.

Abstract: A base exercise device includes at least one modular connection. The base exercise device is operable without any modular units connected to one of the modular connections. A modular unit may be physically connected to the base exercise device. The modular unit includes at least one exercise feature that is not included in the base exercise device.

Abstract: A magnetic clutch transitions a drivetrain or flywheel between a freewheel or unlocked mode or configuration and a locked or fixed gear mode or configuration. The magnetic clutch includes a rotor rotationally fixed to the pedals of the drivetrain. An armature is connected to the flywheel. A field coil generates a magnetic field which causes the armature to move to the flywheel. Friction between the armature and the rotor rotationally fixes the flywheel to the rotor.

Abstract: A pedaled drivetrain includes a drive mechanism, a wheel, a freewheel hub, and a locking mechanism. The wheel has a rotational axis. The freewheel hub connects the drive mechanism to the wheel, and the freewheel hub transmits torque from the drive mechanism to the wheel in a first rotational direction around the rotational axis. The locking mechanism has a locked state and an unlocked state. The locked state rotationally fixes a component of the drive mechanism to the wheel relative to the rotational axis.

Abstract: A treadmill includes a tread belt that is rotatable in a forward direction and a backward direction. Before changing rotation directions on the tread belt, the treadmill implements a safety action. The safety action includes an alert and input in response to the alert to improve the safety of the user.

Abstract: An adjustable kettlebell includes a cradle safety mechanism and a kettlebell safety mechanism. The cradle safety mechanism includes a position sensor that detects whether the kettlebell is in the cradled position and prevents a motor from rotating to change the weight of the kettlebell if the kettlebell is in the uncradled position. The kettlebell safety mechanism includes a dial retractable into the handle of the kettlebell. When the dial is retracted into the kettlebell, a selection mechanism cannot be rotated to change a weight of the kettlebell.

The workout device may aggregate the configuration change command and the configuration change criterion into a queue of one or more configuration change commands that is stored in a memory of the workout device; and change operation according to the configuration change command in response to determining the configuration change criterion is satisfied.

Abstract: Flagging irregularities in user performance in an exercise machine system. In one aspect of the disclosure, a method may include receiving first performance parameters of a first user associated with a first exercise machine that is executing a video workout program to enable the first user to perform a workout on the first exercise machine. The method may also include detecting an irregularity in the first performance parameters that indicates a performance of the workout by the first user is different than expected. The method may further include, in response to the detecting of the irregularity, displaying a visually discernable indication with a first performance indicator of the first user to visually indicate the irregularity.
