A weight stack isolator comprises an impact damper having a rail void therein configured to receive a guide rail of a selectorized machine. The impact damper is shaped to at least partially surround a section of the guide rail when received in the rail void, to secure the weight stack isolator to the selectorized machine. The weight stack isolator may include a slit extending from its outer perimeter to the rail void or the rail void may extend to the outer perimeter, to removably receive the guide rail in the rail void. The weight stack isolator can be positioned under a weight stack of the selectorized machine to absorb or dampen noise and vibration.

The present invention relates to an improved fitness device; specifically, the present invention relates to a stationary fitness machine designed to strengthen multiple muscle groups including the abdominal, chest, intercoastal, latissimus dorsi, rhomboid, deltoid, bicep, forearm, oblique and gluteus maximus muscles using a unique, advanced, combined pull-up, fly movement.

An exercise including a horizontal rail having a proximal end and a distal end. The rail is supported at a height by two or more vertical supports at the proximal end and distal end. A fixed member is positioned at the proximal end of the rail and have a pair of handles and a pair of arm support, wherein the positions of the pair of handles correspond to the positions of the two arm supports. The exercise apparatus includes a slide member slidably mounted to the rail and slide between the distal end and the fixed member. A user can kneel on the slide member while gripping the two handles and having the arms supported by the two arm supports. Once in position, the user can pull the slider member towards the fixed member against the resistance of a resistance mechanism.

A bi-directional exercise machine has a work arm, first and second cams coupled to the work arm, a resistance mechanism, and a pulley assembly that couples the resistance mechanism to the work arm via the first and second cams so that movement of the work arm is resisted by the resistance mechanism according to first and second resistance profiles provided by the first and second cams, respectfully. A primary pulley cable has a first end coupled to the first cam and a second end coupled to the second cam. When the work arm is in a rest position, the ends of the primary pulley cable extend from cable tracks of the cams, respectively, at a tangent so that the resistance mechanism applies a resistance force on the work arm via the pulley assembly immediately upon movement of the work arm out of the rest position.

An exercise apparatus with an adjustable rotating element around which a force transferring material wraps either clockwise or counterclockwise to provide bidirectional rotational resistance for exercising. The force transferring material is preferably guided to remain in close proximity to the rotating element while wrapping around the rotating element.

A reversible resistance exercise machine for reversing the direction of applied resistance against a movable platform of an exercising machine. The exercise machine has a frame, a carriage movably positioned upon the frame, and a plurality of biasing members. A plurality of first tension connectors are accessible near the first end of the carriage and are adapted for removably attaching selected biasing members near the first end of the carriage to resist motion of the carriage in the first direction. A plurality of second tension connectors are accessible near the second end of the carriage and are adapted for removably attaching selected biasing members near the second end of the carriage to resist motion of the carriage in the second direction. A user selectable amount of force may be applied to the carriage to resist movement in either of the first direction and the second direction.

Implementations of squat machines may include a seat coupled to a platform, a first foot brace directly coupled to the platform, a second foot brace directly coupled to the platform, a knee brace post coupled to and extending perpendicularly away from a first surface of the platform, a knee brace arm directly coupled to the knee brace post and extending perpendicularly away from a longest length of the knee brace post, and a knee brace directly coupled to the knee brace arm. The knee brace may be configured to contact the front of either a user's knees or shins while performing a squat exercise. The seat may be configured to temporarily contact a buttocks of a user while performing the squat exercise.

An exemplary exercise device includes, among other things, an attachment structure configured to be mounted to a support assembly, a first arm directly pivotably connected to the attachment structure, a second arm directly pivotably connected to the attachment structure, a bracket directly pivotably connected to the first arm and directly pivotably connected to the second arm, and a catch member configured for accepting a weight bar. The catch member is pivotably connected to at least one of the first arm, the second arm, or the at least one bracket such that the at least one catch member is pivotable relative to the at least one bracket.

The fitness display apparatus comprises an outer housing provided on guide rails (1) and capable of moving under the limit of the guide rails (1); a display screen (14) is provided on the outer housing, the outer housing is internally provided with a generator (11), a PCB (12), a tension sensor (9) and a rechargeable battery (10), the PCB (12) is provided with a charging circuit and a control chip; the generator (11) is connected to the rechargeable battery (10) by means of the charging circuit; a rotor of the generator (11) is in contact with the guide rails (1), and when the outer housing moves, the rotor of the generator (11) rotates; the rechargeable battery (10) is electrically connected to the PCB (12); the tension sensor (9) and the display screen (14) are respectively electrically connected to the PCB (12); and the tension sensor (9) is provided between an external device and a load bearing rod (3). By providing a display unit, exercise data can be intuitively displayed; obtained data can be sent to a mobile device or a cloud by means of a wireless module, and an exercise process is accurately described in combination with a suitable APP and other software, laying a foundation for datamation of training processes and training effects.

The present invention relates to an exercise method and an exercise device for performing an exercise suitable for thigh and hip muscles like fitness equipment or an exercise bicycle, and more particularly, to an exercise method and an exercise device for strengthening thigh and hip muscles by performing a movement of lowering legs and then moving the legs backward or putting the legs together or apart from a position of pulling the legs toward a chest of the user with an arm disposed between the legs in a sitting or lying position of the user. In addition, the present invention relates to a leg exercise device including a trajectory measuring device of generating motion range information of the exercise device and making the motion range information as data through a motion range measurement sensor attached to a knee and a hip joint of the user seated on the exercise device, smart device and an application of the smart device.
