The present disclosure discloses a calibration method for output force of strength-type intelligent fitness equipment, which belongs to the field of intelligent fitness, including: connecting a tension detection device to the strength-type intelligent fitness equipment; obtaining an actual tension of the strength-type intelligent fitness equipment by turning on the tension detection device to perform detection; obtaining a tension deviation based on a target tension of the strength-type intelligent fitness equipment and the actual tension; and calibrating the strength-type intelligent fitness equipment based on the tension deviation.

A fitness exercise apparatus includes a base member, a support unit disposed on the base member, and a pivot assembly disposed on the support unit. A seat frame includes a guide rail having a front end provided with a pivot connecting member pivotally connected to the pivot assembly. The seat frame is pivotally movable to different angular positions relative to the base member. An elastic cord unit includes a plurality of first and second elastic cords connected to the support unit. A pulling unit includes two first cables connectable with the first elastic cords. An operating unit is connectable with the first cables.

A resistance adjustable exercise device, including a resistance assembly to provide resistance to movement, a handle assembly connected to at least a portion of the resistance assembly to move the resistance assembly in at least one of a first rotational direction and a second rotational direction, and a control unit disposed on at least a portion of the handle assembly to adjust at least one of a first resistance level and a second resistance level of the resistance assembly.

An adjustable resistance band for exercise or physical therapy apparatus including a webbing hook component, strap and slots with openings for adjustability in which the band is easily secured around the user's legs or torso by placing the webbing hook in one of the loop openings.

Exemplary arrangements provide leg training devices suitable for high intensity training of hip flexors while simultaneously training the extensors of hip and knee joints. The exemplary leg training devices include foot fixings which are permanent vertically movable components of the device, each of which are configured to releasably engage a foot of a user in operative engagement therewith while limiting the movement of the foot relative to the foot fixings. Each of the foot fixings is operatively connected to a suitable mechanism that provides a resistance force to vertical movement of the foot fixing by the user's leg. In exemplary arrangements the resistance force may be selectively variable with regard to the magnitude and/or point of application so as to provide the desired training regimen.

An exercise system includes a base module having a seat with a seat depth, and a vertically adjustable back configured to fixedly engage with the base module at a first seat depth and a second seat depth different from the first seat depth.

A resistance device capable linearly adjusting training load comprising: a rack unit with two vertical rods, and two sliding units, which are connected to a handle and a pedal; a linkage unit with a chain and a belt, and are locked on the connecting plate; and two damping units make multiple magnet pieces arranged on both sides of a fixing base, and a diamagnetic metal piece is arranged on the connecting plate, and set trough the fixing base to cut the magnetic circuit generated by the magnet pieces to form damping: When the user steps on the pedal, the connecting plate will drive the metal sheet to cut the magnetic circuit, and the damping can be changed to further achieve the effect of linearly adjusting the training load.

A piece of exercise equipment particularly for improved strength training exercises. More particularly, the invention relates to equipment that allows the user to vary tension when performing different exercises. The present invention is specifically designed for improved exercise through the variability of a tension component for use in such exercises as the plank exercise, sit-ups, push-ups and supine pull-ups that includes a core support, a guide arm, a head support, and a foot support that work in conjunction to most optimally support the user. The core support, the head support and the foot support are all connected, supported, and elevated from the floor by a central support system.

An isokinetic control module and method for incorporation on both new and existing exercise equipment. The control module replaces standard friction and hydraulic resistance components offering constant speed of the moveable elements of the machine rather than a selected resistance or weight. The constant user-generated resistance prevents injury and enhances strength training of the targeted muscle groups by maintaining constant strain on those muscles throughout the exercise. This method and device incorporates both a PCFC valve and a check valve device, removing all resistance the moment the user stops applying force to the machine. This enhances safety and facilitates the rapid return of the lifting element to its home position between repetitions. An optional graphical display is also disclosed.

Disclosed herein is an exercise machine that includes an elongated frame having a head end and a foot end, and a moveable carriage slidably coupled to the elongated frame and moveable between the head end and the foot end, the moveable carriage having a spring bracket coupled to an underside of the moveable carriage. The exercise machine also includes a spring support rod slideably coupled with the elongated frame and disposed adjacent the foot end, and selectively positionable with reference to the foot end by a handle that extends from an interior area of the elongated frame to an exterior area of the elongated frame. The exercise machine also includes at least one resistive member coupled at a first end with the spring support rod and at a second end with the spring bracket, and configured to bias the moveable carriage towards the foot end of the elongated frame.
