An exercise device with a redundant monitoring and control circuit integrated within or otherwise in communication with various components of the exercised device to detect and act on real or possible improper operation of the exercise device. A redundant controller may, based on a determination of a potentially out of specification operating condition of the exercise device, transmit one or more control signals to alter (e.g., reduce or remove) power to the motor of the exercise device. The redundant controller may provide a control signal to a motor power gating device to remove power transmitted to the motor from a power source and/or enable an inhibitor line of a motor controller to disconnect main power from the motor. Controlling the motor power gating device and the inhibitor line may ensure that power is removed from the motor even when a conflicting signal is being transmitted to the motor.

This disclosure addresses an exercise device adapted to enable the user to perform a salmon ladder exercise. The ladder includes a frame with at least one pair of support protrusions that receive an exercise bar. A bearing surface that receives the shaft of a catch array rotatably mounted in the frame. The device further includes a braking mechanism that applies a variable suppression force to the catch array shaft, the variable suppression adjusting the force required to rotate the catch array shaft in the bearing surface.

An apparatus is provided for use in resistance training. The apparatus may include a bar with pulley hubs on its ends. The apparatus may further include two slings, each including connectors and a rigid, straight or arc-shaped bar. The slings may be suspended from the pulley hubs and support an elastic band, which may provide resistance during exercise. A footplate may also be provided to hold part of the band to the floor during use.

The embodiments herein relate to an exercise machine for training the muscles of the whole body while specifically targeting the muscles of the legs and back. Specifically, the embodiments herein relate to a Reverse Deadlift Apparatus which allows a trainee to mimic a barbell type deadlift exercise in a safer and more productive fashion. An additional benefit is that the Reverse Deadlift Apparatus encourages a lifter to use proper technique by requiring them to use more of their legs and less of their lower back during the lift. The result of using the Reverse Deadlift Apparatus on a regular basis is that a lifter will increase the strength and power of the muscles of the whole body and specifically will make improvements in the lower body. The added strength and power, along with optimized Deadlifting form, will help a lifter improve their performance in the actual barbell deadlift itself and in any sports requiring a strength or power component (e.g. Football, Baseball, Martial Arts, Wrestling, Powerlifting, Olympic Lifting, Tennis, etc.).

A low friction rehabilitation board having an integral band retaining feature is described. The rehabilitation board may have a coefficient of static friction of no more than about 0.5 and in some embodiments no more than about 0.06. The rehabilitation board has a plurality of band retaining feature configured along one or both ends and may be an integral band retaining features being formed in the board. Additionally, the rehabilitation may include one or more band retaining features on one or both sides of the board. The unique configuration of the band retaining features enables rehabilitation method heretofore not possible with a single board. Resistance bands may be retained in the band retaining features and coupled to a user's limb, such as a foot or ankle, to resist motion, such as sliding or extending the foot along the low friction surface of the rehabilitation board.

Provided is an artificial intelligence (AI) workout guide apparatus including a personal maximum weight (PMW) estimator configured to estimate PMW.sub.estimation of fitness equipment to be used by a user, based on an estimated muscular strength value calculated based on user data, and a PMW guider configured to provide PMW.sub.individual for the fitness equipment by complementing the PMW.sub.estimation with an individual objectification index of the user.

A workout device that allows for at home Nordic hamstring curls using a. doorframe or other immovable object is disclosed.

An aqua resistance dumbbell comprises a tubular wall that provides a bore for receiving a user's hand from each end of the bell. A rod is located within the bore and extending laterally across the bore to be gripped by a user with one or both hands from one or both ends of the bore. The dumbbell has a plurality of longitudinal fins extend along the tubular wall on an outer side of the tubular wall, and at least one lateral fin that extends laterally at least part way around the tubular wall. An aqua resistance fin assembly comprises two fin components and at least one fastening member for fitting the fin components to a user's limb in a side-by-side configuration around the limb. Each fin component comprises a base adapted to fit against a user's limb and adapted to be secured to the user's limb by the fastening member, and at least two longitudinal fins and at least one lateral fin on an outer side of the base.

A system may include an exercise device and an external device. The exercise device may include a rigid rod, a plurality of light sources, at least one load sensor for detecting an applied longitudinal force, and a first processor coupled to the at least one load sensor and to the plurality of light sources and configured to obtain a signal indicating a magnitude of the applied longitudinal force, and cause a subset of the plurality of light sources to emit light. The external device may comprise a communication interface, a display, and a second processor coupled to the communication interface and to the display and configured to establish a communication link with the exercise device using the communication interface, obtain data over the communication link, and cause the display to present information associated with the exercise device.

A versatile weight device for physical fitness routines is disclosed which comprises a plate having a generally H-shaped body having a first leg having an end having a hand grip portion, a second leg having an end having a hand grip portion, a third leg having an end having a hand grip portion, a fourth leg having an end having a hand grip portion, a first handle spanning between the first leg and the fourth leg, a second handle spanning between the second leg and the third leg, a central bore, a first cutout section formed between the first leg, the first handle, and the fourth leg, a second cutout section formed between the first leg and the second leg, a third cutout section formed between the second leg, the second handle, and the third leg, and a fourth cutout section formed between the third leg and the fourth leg.
