An exercise machine is provided which is configured to place a user in an exercise position, wherein movement during exercise against a load will target the gluteus maximus muscles. The exercise machine positions the body of a user in a lowered or exercise position which supports the user while raising their body to an elevated position, in a manner to stabilize the user and direct movement of the user along the sagittal plane during use, while concurrently isolating the gluteus maximus muscles as the muscles overcoming the load.

An exercise device configured to provide for a lifter performing a bent-over row exercise. The exercise device provides lower back support and stability to the lifter. Embodiments of the device may be attachable to an exercise rack or be configured as a standalone device. An embodiment of the exercise device may comprise an adjustable support pad configured to support the chest of a lifter. The adjustable support pad rotates about an axis to optimize comfort and alleviate lower back strain during bent-over row exercises.

An exercise device includes a base defining an inner volume and a top supported by the base, the top defining an aperture. The exercise device further includes a force sensor configured to measure force on the top and a motor disposed within the base and below the top, the motor including a cable extendable through the aperture. The exercise deice further includes a controller communicatively coupled to each of the force sensor and the motor. The controller is adapted to actuate the motor in response to forces applied to the top as measured by the force sensor. The controller may also actuate the motor in response to one or more additional parameters related to the speed or force with which the cable is manipulated (e.g., pulled by a user).

An exercise device of the type including a frame with a first crank assembly rotatably coupled to the frame about a first axis and a second crank assembly rotatably coupled to the frame about a second axis. A control system may be used in communication with the first crank assembly and the second crank assembly, which may provide a synchronous movement of the first crank assembly relative to the second crank assembly. A pedal arm may be provided with a first end pivotally coupled to the first crank assembly and a pedal positioned on a second end. A crank link may be used with one end coupled to the second crank assembly and a second end coupled to the pedal arm. The crank link may be movable on the pedal arm which may provide varying paths of motion of the pedals.

An improved exercise machine has a stationary longitudinal monorail structure that extends between front and back end stationary exercise platforms, and an exercise platform mounted on a levitated carriage that is reciprocally movable along the monorail between the stationary platforms. Magnetic elements arranged on various opposing surfaces of the carriage and monorail generate magnetic forces that levitate and stabilize the carriage as it moves relative to the monorail thus substantially eliminating contact friction. Springs selectively attachable to the movable platform provide a resistance force for exercising. Pseudo-levitation and eddy brake elements on the carriage and monorail structure further stabilize the carriage and platform.

An adjustable exercise machine for performing resistance exercises comprises a base and an upper frame including front and back end stationary exercise platforms, and a movable exercise platform that reciprocates between the stationary platforms. A plurality of biasing members is selectable by an exerciser via selector knobs to generate a bias force against the movable platform. A plurality of pivotable lift supports are connected between the base and the upper frame. Front and back actuators are connected between the base and the lift supports by lifting yokes to selectively raise and lower the front and back ends of the machine. The movable platform may be connected to move along the exercise machine by trolley wheel assemblies. A plurality of travel limit decelerators mounted on the rails engage and rapidly decelerates the movable platform as it reaches its limits of travel on the rails.

An exercise apparatus includes a frame with a pair of vertical guides. A carriage is slidably carried on each of the guides. Each of the carriages has a locking mechanism to lock the carriage at a selected vertical position and a release to disengage the locking mechanism. A horizontal exercise bar is slidably carried on guide rods. First and second cables are coupled to a selectable exercise resistance, each of the cables having an end selectively coupled to either the respective carriage or to a respective bracket at the end of the exercise bar. Secondary brackets on the exercise bar are configured to engage respective ones of the carriage releases and grab the carriage so as to selectively engage and disengage the locking mechanisms upon axial rotation of the exercise bar and raise and lower the carriages with the exercise bar.

An exercise device and system are provided. The exercise device and system are especially suitable for use with sub-maximal to maximal concentric, isometric and eccentric exercises. The exercise device has a back-plate unit, an extended bar and a foot-brace unit. A first and second strap, each having a hand loop, may be grasped by the hands and may be attached to the extended bar and may be connected to the foot-brace unit. An optional scale may be secured to the foot-brace.

A smart box system may include a smart box device. The smart box device may include a top portion, elongated side portions, and side portions. The top portion may include a top set of locking elements configured to mate with an external device to prevent the external device from moving relative the top portion of the smart box device. The elongated side portions may attach to the top portion. The side portions may selectively attach to distal ends of the elongated side portions.

A fitness tool for a user to use in performing stretching or other fitness activities may include a first member including (i) a first elongated shaft, the first elongated shaft including a first interface feature on a first end of the first elongated shaft, and (ii) a handle disposed at the second end. A second member may include a second elongated shaft, where the second elongated shaft may include a second interface feature at a first end of the second elongated shaft. The first and second interface features, when longitudinally engaged with one another, may enable the first and second shafts to rotate relative to one another. The second elongated shaft may include a hand or foot engagement mechanism.
