Accessories that are attachable to fitness equipment may be used to allow users to move the attachment quickly and easily from one position to another by removing the accessory or sliding it along a vertical or horizontal upright that forms part of the fitness equipment or rack. The accessories may come in many forms so that various exercises may be carried out using the accessories on the same fitness equipment or rack.

Apparatus for bi-directional ankle exercise movements has a main-frame with a seat and upwardly extending columns at either side to support a “U” shaped sub-frame, mounted so that it pivots about a horizontal axis passing very nearly through the ankles of a seated user and interconnecting linkages simultaneously enforcing ankle inversion, with plantarflexion and then ankle eversion, with dorsiflexion, about perpendicularly intersecting axes, while resisting such movements, so as to provide bidirectional ankle exercises according to a progressive resistance program, thus strengthening the ankle muscle groups for enhanced balance and dynamic stability.

An upper posterior development device is shown and described. The upper posterior development device includes a frame. The frame is created by a plurality of legs. The legs may be secured to one another at a bottom end for additional support. A bench is secured to the upper end of at least one of the plurality of legs. The bench may be rotatably secured to the frame such that the angle of the bench is adjustable. In this instance the bench is secured at least one different leg of the plurality of legs via an adjustment device. A pendulum movably secured to an underside of the bench. The pendulum is configured to have weight added or removed therefrom.

A weighted-squat exercise machine comprises a pivotable, length-adjustable lever, a weight supported by said lever, a support base, and a hip-belt that connects a user to the machine. Weights are supported by the machine at a safe distance from a user. The weighted-lever has an angle with respect to the horizon with a range of from about 35 degrees to about 45 degrees. When a user wearing the hip-belt connects it to the weighted-lever, the weight's gravitational force is transferred to the user providing for the user to perform weighted squats in a safe manner as the weights are spaced from the user. Thus, athletes can safety exercise without a spotter even if using 1000 pound weights. The belt supports the weight about the athlete's hip structure so that there is no stress on the user's neck and spine and no restriction in breathing.

A multifunctional fitness system may allow for high-resistance exercises through the distribution of weight upon a frame pivoting on the ground. In particular implementations, while a user lifts one end of the frame, the opposite end pivots. The weight of another person (and/or that of conventional weighted plates) can be placed on the frame in locations yielding the desired leverage and, thus, resistance felt by the lifter. The frame may have various axes upon which it can pivot and grip points, thus offering a broad range of exercises that can be conducted. Reorienting the frame to be resting on differing sides results in additional feasible exercises. Optional integrated electronics (typically in conjunction with existing smart devices) may use kinematics and/or structural flexing to calculate felt resistance and provide automated instruction to the various users. The may also collapse into a compact, rollable configuration for easy transport.

An exercise device for strengthening muscles is disclosed, having a continuous belt system that allows a user to move the continuous belt using their feet to exercise muscles of the person while the person lies in front of the continuous belt with their back braced on a resting surface. Such an exercise device allows a user to exercise their gluteus and hamstring muscles while strengthening their pelvic stabilizers. The exercise device could also have a weight device that allows a user to rest a weight on their torso during the exercise to increase the difficulty and effectiveness of the exercise.

A method for identifying and correcting muscular and skeletal disbalances through exercise includes recording, by a processor, using at least one sensor coupled to the processor, an exercise motion performed by a user, identifying, by the processor, a motion deficiency of the user based on the detected exercise motion, formulating, by the processor, a corrective motion based on the detected motion deficiency, and providing, by the processor, the corrective motion to the user, which also includes identifying motion deficiencies as far as range of motion, balance, symmetry, smoothness, strength, stamina and other motion characteristics, formulating corrective exercise program that involves multiple training machines, formulating exercises in terms of number of repetitions, cadence (frequency) or motion, range of motion, added resistance levels, communicating the corrective exercise program via the screen embedded on each machine, and guiding the user through each exercise, directing user to change exercise machines.

An arm curl fitness apparatus includes a first frame to be provided standing upright on both sides of the user in a straight bar shape; a second frame formed in a U-shape with each end coupled to the upper end of the first frame; a first rotation bar, shorter than the first frame, with one end rotatably coupled to the upper outer side of the first frame; a handle formed in a L-shape with one end rotatably coupled to the first rotation bar and the other end facing the user; a second rotation bar with one end rotatably coupled to the lower outer side of the first frame; a wire with one end connected to a point adjacent to one end of the first rotation bar; and an armrest provided on the inside of the upper part of the first frame.

An exercise machine with electromagnetic resistance selection for changing exercise resistance settings by engaging more or fewer resistance biasing members using a electromagnets. An example implementation includes a movable carriage configured to move substantially along the length of one or more rails. A plurality of resistance biasing members are removably attachable between a stationary biasing member bracket affixed to the machine structure and the movable carriage. A controller changes the resistance settings against the movable carriage by electrically attaching or detaching any preferred number of resistance biasing members between the machine structure and movable carriage.

A machine for concurrently or independently performing pressing motions with the hands and feet, the machine having a base having front and back ends, two or more linear slide rails, a lower body user support with an engagement means for the user's feet and an upper body user support with an engagement means for the user's hands. The upper body user support and lower body user support slide on the linear rails that are located proximally on opposing ends of the base frame and the upper body user supports and the lower body user supports cooperate with one another to move in opposing converging and diverging sloping linear movement patterns during operation of the machine.
