An exercise device for alternating movement of arms and legs by which users perform alternating active exercises and passive exercises repetitively is revealed. The exercise device includes a base, a hand driving member, and a leg driving member. Both the hand and leg driving member are pivotally connected to the base while the leg driving member is arranged under the hand driving member. One end of the hand driving member and one end of the leg driving member are configured to be pivotally rotated on the base. The hand and leg driving members are pivotally connected by a linkage. By the pivotal connections of the above parts, the hand and leg driving members are linked and moved with each other so as to lift up or press down arms and legs for stretching. The stretching of arms and legs also generates pressure on the abdomen of the user to exercise his or her abdomen.

A device including a first member for supporting a user; and a second member 14, attached to the first member, including a counterbalance portion. The first member and the second member are each moveable, and operable to slide with respect to each other in opposite directions, between a first position and a second position. The device can be operable such that between the first and second positions, the combined center of mass of the device 10 and its user remains substantially fixed. This serves to reduce the extent of forces and vibrations generated by use of the device on the object to which the device is located.

A non-limiting example training instrument comprises a hollow main body formed of an aluminum alloy. The main body is constituted by two gripping portions opposite to each other with a space therebetween and a coupling portion coupling the two gripping portions. A load sensor is arranged in the coupling portion inside the main body. The load sensor is a load cell, a strain gauge affixed to an interior of the main body, and a part of the main body to which the strain gauge is affixed functions as a strain body. Therefore, if a user applies a force so as to bring the two gripping portions close to each other or a force so as to move the two gripping portions away from each other, a load thereof is detected by the load sensor.

An exercise apparatus that includes a handle frame and a base frame.

A folding exercise chair for resistance training has a collapsible chair frame, a pair of resistance mechanisms, and a padded cross-brace. The collapsible chair frame has a seat and a height-adjustable backing. The height adjustable backing is an assembly that enables a user to modify the height of the collapsible chair frame's backrest. The padded cross-brace is connected offset from the seat and across the collapsible chair frame to support the user's back and add comfort while the user is exercising. Each of the pair of resistance mechanisms is a device used to facilitate resistance training exercises. To that end, each of the pair of resistance mechanisms is positioned on either side of the collapsible chair frame.

An exercise machine may include a frame, a resistance mechanism supported by the frame, and a console configured to control the resistance mechanism and guide a user through a workout using the exercise machine using a projected visual indicator to assist a user in performing the workout properly.

An exercise device that exercises both flexor and extensor muscles is provided. The exercise device includes a base having a front end, a rear end, a first side and a second side. Protruding from the rear end of the base is an anchor bar. The anchor bar may be substantially perpendicular to the base. An overhead handle bar may be pivotally connected to the top of the anchor bar by a pivot point. A stationary fulcrum may be secured to opposing sides of the base. A rotating rod is secured to the stationary fulcrum and rotates about a horizontal axis running through the rotating rod and the fulcrum. A slant board is supported by and pivots about the rotating rod.

A training or exercise apparatus may have a base and an adjacent movable armature or frame that carries a riding member, or shuttle, or carrier. The carrier has an engagement interface with an element of sporting or exercise equipment. The sporting or exercise equipment is engaged by the user, typically by being grasped. The apparatus defines a physical or virtual schedule describing an arc for a swing in the particular activity. The apparatus may include a manual or electronic means of imposing resistance to the motion. This resistance may be adjustable, and may be programmable as a function of one or both of position and speed. The apparatus may include an array of sensors such as may be used to determine the pre-existing stroke, and such as may be monitored during training to assess progress. The apparatus may be operated passively, or it may be operated interactively in a manner in which real-time feedback causes the apparatus to adjust resistance to the motion.

A core muscle therapy apparatus is presented. The apparatus is designed to work the muscles comprising the core of a user by allowing the user's own body weight to resist the force of gravity in up to a 360 degree environment. The core muscle therapy apparatus has a base, a cage assembly, and a seat assembly.

A resistance band system including a frame-assembly, a plurality of linear-straps, and a plurality of removable-D-rings. The frame-assembly, the plurality of linear-straps and plurality of removable-D-rings of the resistance band system are structured and arranged in combination to allow a user to affix a linear-resistance-band to the resistance band system to provide an overall exercise system which provides the user with a plurality of locations to affix the linear-resistance-band to the resistance band system to allow a highly flexible and diverse exercise system to the user. The frame-assembly includes an upper-frame, a lower-frame, and a u-member. The upper-frame includes two primary-members, two inbars, two forward-bars, and a crown-bar. The lower-frame includes two first-members, two downbars, and down-cross-member. The u-member comp includes rises a body, two legs, and two t-couplers, with u-member rotatably coupled to the lower-frame via the two t-couplers.
