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 machine is provided with a loading device. The loading device includes a lever, a coupler, a cylinder unit and a driving unit. The lever includes two ends. The first end of the lever is connected to the exercise machine. The coupler is movable along the lever between the first and second ends. The cylinder unit includes an end connected to the exercise machine and another end connected to the coupler. The driving unit includes a threaded sleeve, a threaded rod and a motor. The threaded sleeve is connected to the coupler. The threaded rod is engaged with the threaded sleeve. The motor rotates the threaded rod relative to the threaded sleeve so that the threaded rod moves the coupler via the threaded sleeve.

A vertically oriented fitness apparatus utilizes a combination of upper and lower assemblies resistant to vertical motion when the user pushes and pulls against crossbar members of the assemblies vertically. In alternate embodiments of the apparatus, resistance is provided by a dual action dashpot such as an adjustable bidirectional hydraulic damping cylinder which may be used in combination with spring resistance elements. The user is thus able to perform strength training and fitness conditioning exercises for both upper and lower extremities, and their core simultaneously while using the apparatus.

An exercise machine support system for providing increased versatility including inclination or declination of an exercise surface, a reduction in the overall length and width of the exercise machine, and an enhanced user interface which reduces the risk of injury. The exercise machine support system generally includes a cantilevered exercise machine which is adapted to have a variable angle of incline or decline with respect to a horizontal ground surface. The exercise machine will generally include a base and a support which extends between the base and the exercise machine. The upper end of the support is connected to the exercise machine by a first pivot such that the exercise machine pivots about the support. An adjustment device may be utilized to pivot the exercise machine and thus adjust its angle of incline. Various types of adjustment devices are disclosed, including an actuator, ratchet-and-pawl, gears, and cam.

An exercise machine inclination device for providing variable exercise intensity on an exercise machine by inclining the exercise machine. The exercise machine inclination device generally includes a base adapted for being positioned upon a floor, a support structure adapted for supporting the exercise machine, a hinge pivotally connecting the base and the support structure and an actuator connected between the base and the support structure, wherein the actuator adjusts an angle of the support structure.

An exercise machine using motion sensor to track exercise, comprising: an exercise equipment, including a mainframe, the mainframe is fixed and won't be moved by user's movement, an operating mechanism, the operating mechanism is arranged on the mainframe and it will follow the movement of the user; wherein the operating mechanism having a motion sensor, inside the motion sensor having a multiple-axis tracking sensor module and a first microprocessor for detecting the height displacement of the operating mechanism and transmitting the height displacement signal to an electronic control device, then processing by a second microprocessor arranged inside the electronic control device to know whether the motion track of the user reach the preset position during exercise to ensure the effect of exercising.

An exercise machine resistance adjustment system for providing an exerciser the ability to immediately adjust the resistance force by changing their body position on the movable carriage or end platforms. The exercise machine resistance adjustment system generally includes a frame, a carriage movably positioned on the frame, a spring connected to the carriage to apply a biasing force to the carriage, one or more left projections within the carriage adapted for a left hand of an exerciser to grasp, and one or more right projections within the carriage adapted for a right hand of an exerciser to grasp. The exerciser is able to efficiently adjust the amount of resistance force applied to the carriage by repositioning their hands (or feet) from a first set of projections at a first distance to a second set of projections at a second distance from the first end of the exercise machine.

A treadmill which utilizes provides for a connection between the floor stand and the treadbase which is toward the front end of the treadbase and provides for generally improved support of the front end of the treadbase at higher angles by providing that the lift mechanism is attached to the treadbase at two fixed points a fixed distance from each other. The lift mechanism then utilizes two different motions, the extension of an extension arm and the rotation of a rigid arm, to produce lift. The rotation of the rigid arm generally utilizes a wheel in an enclosed raceway attached to the floor stand.

The invention is directed to systems, devices, and methods for measuring force and repetitions during exercise or rehabilitation activities. Devices in accordance with embodiments may include: a casing; a processor within the casing; a display visibly on the casing; a first attachment portion on one end of the casing; a second attachment portion on an opposite end of the casing; and a force sensor connected to the first and the second attachment portion, the force sensor in communication with the processor. Methods may include: attaching a pneumatic exercise device to the wireless force measurement device; conducting exercises causing a piston in the pneumatic exercise device to move compared to from the wireless force measurement device; counting, by the device, the number of times the piston moves towards or away from the device; determining, by the device the amount of force applied through the pneumatic exercise device during the exercise.

An exercise machine for assisting in the performance of a core exercise that is adjustable between a plurality of configurations. The exercise machine includes a front track, a rear track, a first bar operably engaged with the front track and the rear track, a second bar operably engaged with the front track and the rear track, a first handle member operably engaged with the first bar proximate, a second handle member operably engaged with the second bar, a first foot block operably engaged with the first bar, and a second foot block operably engaged with the second bar. The first bar, the second bar, the first handle member, the second handle member, the first foot block, and the second foot block are all selectively adjustable to accommodate users of different shapes and heights as well as variations of core exercises.
