A device for physical therapy includes a base on which a sliding platform is mounted. One or more of a plurality of springs may be selected to act between the base and the platform to tailor the resistance of platform motion to a specific therapy or patient. The platform has a removable cushion with a friction inducing surface which a patient may use in conjunction with a friction inducing headband to perform various neck therapies and exercises.

A weight training platform designed to have the ability to use free weights and resistance bands simultaneously, which can increase muscle strength and endurance with repetitive movements and has the advantage of being inexpensive, space conscious, and portable.

The invention relates to a resistance machine, e.g., for exercising. In particular, the machine is lightweight, compact, and modular to allow for ease of transportation and storage. The multifunction machine is also capable of providing variable and high resistances for many types of weight training methods, such as powerlifting.

An exercise machine tension device securing system for safely and efficiently securing selectable biasing members to an exercise machine. The exercise machine tension device securing system generally includes an exercise machine including a frame and a carriage movably positioned on the frame. A plurality of tension devices may be connected to the frame at one end; with the other end being removably connected to the carriage by a selection device. The selection device may include a plurality of slots for removably receiving one or more of the tension devices to secure the tension devices selectively to the carriage. A securing member movably connected to the selection device includes projections adapted to selectively enclose the slots so as to secure the tension devices within the slots of the selection device.

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 monitoring and instruction system for the movement of an element of an exercise machine by an exerciser and providing automated feedback to the exerciser to help improve the exercise in real-time. The exercise machine monitoring and instruction system generally includes an exercise machine having a movable element that moves between a first position and a second position in a reciprocating manner, a sensor that detects a real-time position of the movable element, a processor in communication with the sensor to receive the real-time position data from the sensor related to a position of the movable element and a feedback device in communication with the processor that provides real-time instructions to the exerciser on how to adjust their workout to achieve a desired result.

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 exerciser has a frame, a driving assembly, a damping assembly, and a linkage assembly. The frame has a base and a rear supporting rod. The driving assembly is mounted on the frame and has two swinging rods, two sprockets, two chains, and two resilient members. The swinging rods are connected to the rear supporting rod. The two sprockets are mounted rotatably on the rear supporting rod. The two chains are respectively engaged with the two sprockets. The two resilient members are connected respectively to the chains. The damping assembly is mounted on the rear supporting rod and is connected to the driving assembly to provide a damping effect to the two sprockets. The linkage assembly is connected between the base of the frame and the two swinging rods to allow the two swinging rod to respectively swing in reverse directions.

Rowing machines are described that permit a rower to adjust the rowing resistance using a gear shift mechanism. The rowing machine includes a handle connected to a chain, which passes, sequentially, over a derailleur and then to the gears of the gear cassette. The gear cassette is coupled to a resistance unit, which may be similar to resistance units used in off wheel bicycle trainers. This configuration of derailleur and gear cassette permit the rower to smoothly select a gear.

In one aspect of the disclosure, a motorized Pilates reformer system may include a frame, a carriage configured to slide along the frame, springs attached to the carriage, attachment mechanisms attached to the frame, spring motors attached to the frame, a footbar rotatably attached to the frame, and a footbar motor attached to the frame. The spring motors may be configured to cause the attachment mechanisms to each alternate between attaching one of the springs to the frame and detaching the spring from the frame. The footbar motor may be configured to rotate the footbar with respect to the frame between multiple footbar positions.
